    + + +

    Constructeur

    + + +

    [name]( [param:AnimationMixer mixer], [param:AnimationClip clip], [param:Object3D localRoot] )

    +

    + [page:AnimationMixer mixer] - l'`AnimationMixer` contrôlé par cette action.

    + + +

    Propriétés

    + + +

    [property:Boolean clampWhenFinished]

    +

    + Si `clampWhenFinished` est mis à true l'animation sera automatiquement [page:.paused mise en pause] + à son dernier frame.

    + + Si `clampWhenFinished` est mis à false, [page:.enabled enabled] sera automatiquement reglé sur + false quand la dernière boucle de l'action sera terminée, afin que cette action n'ai pas plus + d'impact.

    + + Note: `clampWhenFinished` n'a pas d'impact si l'action est interrompue (il n'a d'impact que si + la dernière boucle de l'action s'est réellement terminée). +

    + +

    [property:Boolean enabled]

    +

    + Régler `enabled` sur `false` désactive cette action, afin qu'elle n'ai aucun impact. La valeur par défaut est `true`.

    + + Quand l'action est réactivée, l'animation continue depuis son [page:.time time] actuel + (Régler `enabled` sur `false` ne relance pas l'action).

    + + Note: Régler `enabled` sur `true` ne redémarre pas automatiquement l'action. Régler `enabled` + sur `true` ne redémarrera l'action immédiatement que si les conditions suivantes sont remplies: + [page:.paused paused] est à `false`, l'action n'a pas été désactivée (en + exécutant un [page:.stop stop] ou un [page:.reset reset]), et ni [page:.weight weight] + ni [page:.timeScale timeScale] ne sont à `0`. +

    + +

    [property:Boolean paused]

    +

    + Régler `paused` sur `true` met l'exécution de l'action en pause en mettant l'échelle temporelle effective + à `0`. La valeur par défaut est `false`.

    +

    + +

    [property:Number repetitions]

    + + La valeur peut-être restreinte à `0...clip.duration` (selon l'état de la boucle). Il peut être + mis à l'échelle relativement à celui du mixer global en changeant [page:.timeScale timeScale] (en utilisant + [page:.setEffectiveTimeScale setEffectiveTimeScale] ou [page:.setDuration setDuration]).
    +

    + +

    [property:Number timeScale]

    +

    + Facteur de mise à l'échelle pour le [page:.time time]. Une valeur de `0` cause la mise en pause de l'animation. Une valeur + négative fera jouer l'animation à l'envers . La valeur par défaut est `1`.

    [name]

    + +

    + Un KeyframeTrack est une séquence chronométrée de [link:https://en.wikipedia.org/wiki/Key_frame keyframes], + qui est composée de listes de durées et de valeurs connexes, qui sont utilisées pour animer + une propriété spécifique d'un objet. +

    + +

    + Pour avoir un aperçu des différents éléments du système d'animation de three.js, consultez + l'article "Système d'Animation" dans la section "Étapes Suivantes" du manuel. +

    + +

    + Contrairement à la hiérarchie d'animation du + [link:https://github.com/mrdoob/three.js/wiki/JSON-Model-format-3 JSON model format] un + `KeyframeTrack` ne stocke pas ses keyframes comme étant des objets dans un tableau à "clés" (stockant + les durées et les valeurs pour chaque frame ensemble à un même endroit). +

    + +

    + A la place, il y a toujours deux tableaux dans un `KeyframeTrack`: le tableau [page:.times times] + stocke les durées pour chaque keyframes de ce track dans un ordre séquentiel, et le tableau + [page:.values values] array contient les valeurs modifiées correspondantes de la propriété animée. +

    + +

    + Une simple valeur, appartenant à un certain point temporel, ne peut pas simplement être un nombre, mais (par + exemple) un vecteur (si c'est une position qui est animée) ou un quaternion (si c'est une rotation qui est animée). Pour + cette raison, le tableau de valeurs (qui est également un tableau à une dimension) peut être de trois ou quatre fois la taille du + tableau de durées. +

    + +

    + Il existe plusieurs sous-classes de `KeyframeTrack` correspondant aux différents + types possibles de valeurs animées, héritant de la plupart des propriétés et méthodes: +

    + +
      +
    • [page:BooleanKeyframeTrack]
      • +
    • [page:ColorKeyframeTrack]
      • +
    • [page:NumberKeyframeTrack]
      • +
    • [page:QuaternionKeyframeTrack]
      • +
    • [page:StringKeyframeTrack]
      • +
    • [page:VectorKeyframeTrack]
      • +
    + +

    + Quelques exemples qui montrent comment créer manuellement un [page:AnimationClip AnimationClips] avec différentes sortes + de KeyframeTracks peuvent être trouvés dans le fichier [link:https://threejs.org/examples/jsm/animation/AnimationClipCreator.js AnimationClipCreator]. +

    + +

    + Étant donné que les valeurs explicites ne sont spécifiées que pour les points temporels discrets stocké dans le tableau de durées, + toutes les valeurs du milieu doivent être interpolées. +

    + +

    + Le nom du track est important pour la connexion de ce track avec une propriété spécifique du + node animé (fait par [page:PropertyBinding]). +

    + + +

    Constructeur

    + + +

    [name]( [param:String name], [param:Array times], [param:Array values], [param:Constant interpolation] )

    +

    + [page:String name] - l'identifiant du `KeyframeTrack`.
    + [page:Array times] - un tableau des durées des keyframes, convertis en interne en un + [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Float32Array Float32Array].
    + [page:Array values] - un tableau avec les valeurs concernant le tableau de durées, convertis en interne en un + [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Float32Array Float32Array].
    + [page:Constant interpolation] - le type d'interpolation à utiliser. Voir + [page:Animation Animation Constants] pour les valeurs possibles. La valeur par défaut est [page:Animation InterpolateLinear]. +

    + + +

    Propriétés

    + + +

    [property:String name]

    +

    + Le nom du track peut faire référence à des morph targets ou à des [page:SkinnedMesh bones] ou possiblement d'autres valeurs de l'objet animé. Voir + [page:PropertyBinding.parseTrackName] pour les types de strings qui peuvent être assemblés: +

    + +

    + Le nom peut spécifier le noeud en utilisant son nom ou son uuid (bien qu'il doive être dans le + sous-arbre du noeud du graphe de scène passé dans le mixer). Ou, si le nom du track commence par un point, + le track s'applique au noeud racine qui a été passé en paramètre du mixer. +

    + +

    + Généralement après le noeud une propriété est spécifiée directement. Mais vous pouvez également spécifier une + sous-propriété, comme .rotation[x], si vous voulez seulement contrôler X composants de la rotation + via une float track. +

    + +

    + Vous pouvez également spécifier des bones ou des multimatériaux en utilisant un nom d'objet, par exemple: + .bones[R_hand].scale; le canal rouge de la couleur diffuse du quatrième matériau dans un + tableau de matériaux - comme autre exemple - peut être accédé avec .materials[3].diffuse[r]. +

    + +

    + PropertyBinding résoudra également les noms de morph target, par exemple: .morphTargetInfluences[run]. +

    + +

    + Note: Le nom de track ne doit pas nécessairement être unique. Plusieurs tracks peuvent gérer la même + propriété. Le résultat doit être basé sur un mélange pondéré entre les mutiples tracks selon + le poids de leurs actions respectives. +

    Constructeur

    +

    [name]( [param:TypedArray array], [param:Integer itemSize], [param:Boolean normalized] )

    +

    + [page:TypedArray array] -- Doit être un [link:https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/TypedArray TypedArray]. + Utilisé pour instancier un tampon (buffer).
    + Ce tableau devrait avoir + itemSize * numVertices + éléments, où numVertices est le nombre de sommets dans le [page:BufferGeometry BufferGeometry].

    + [page:Integer itemSize] -- Le nombre de valeurs du tableau qui doivent être associées à + un sommet particulier. Par exemple, si l'attribut stocke un vecteur à 3 composants (tel qu'une position, une normale ou une couleur), alors itemSize doit être 3. +

    + + [page:Boolean normalized] -- (optionnel) S'applique uniquement aux données entières. Indique comment les données sous-jacentes + dans le tampon correspond aux valeurs du code GLSL. Par exemple, si [page:TypedArray array] est une instance de + UInt16Array, et [page:Boolean normalized] est `true`, les valeurs `0 - +65535` dans le tableau + de données seront mappées à 0.0f - +1.0f dans l'attribut GLSL. Un Int16Array (signé) mapperait + de -32768 - +32767 à -1.0f - +1.0f. Si [page:Boolean normalized] est faux, les valeurs + sera converti en flottants non modifiés, c'est-à-dire que 32767 devient 32767.0f. +

    Constructeur

    + + +

    [name]()

    +
    + Cela crée un nouveau [name]. Il définit également plusieurs propriétés sur une valeur par défaut. +
    + + +

    Propriétés

    + +

    [property:Object attributes]

    +

    + Ce hashmap a comme identifiant le nom de l'attribut à définir et comme valeur le [page:BufferAttribute buffer] à lui attribuer. + Plutôt que d'accéder directement à cette propriété, utilisez [page:.setAttribute] et [page:.getAttribute] pour accéder aux attributs de cette géométrie. +

    + +

    [property:Box3 boundingBox]

    +

    + Boîte englobante pour le bufferGeometry, qui peut être calculée avec + [page:.computeBoundingBox](). La valeur par défaut est `null`. +

    + +

    [property:Object drawRange]

    +

    + Détermine la partie de la géométrie à rendre. Cela ne devrait pas + être défini directement, utilisez à la place[page:.setDrawRange]. La valeur par défaut est + + { start: 0, count: Infinity } + + Pour BufferGeometry non indexé, count est le nombre de sommets à rendre. + Pour BufferGeometry indexé, count est le nombre d'indices à rendre. +

    + +

    [property:Array groups]

    +

Count spécifie combien de sommets (ou indices) sont inclus, et + materialIndex spécifie l'index de tableau de matériaux à utiliser.

    + + Utilisez [page:.addGroup] pour ajouter des groupes au lieu de modifier le tableau directement.

    + + Chaque sommet et index doit appartenir à exactement un groupe — les groupes ne doivent pas partager de sommets ou d'indices, et ne doivent pas laisser de sommets ou d'indices inutilisés. +

    + +

    [property:Boolean morphTargetsRelative]

    +

    + Utilisé pour contrôler le comportement de la cible de morphing ; lorsqu'il est défini sur true, les données cibles de morphing sont traitées comme des décalages relatifs, plutôt que comme des positions/normales absolues. + + La valeur par défaut est "faux". +

    + +

    [property:String name]

    +

    + Nom facultatif pour cette instance de bufferGeometry. La valeur par défaut est une chaîne vide. +

    + +

    [property:Object userData]

    +

    + Un objet qui peut être utilisé pour stocker des données personnalisées sur le BufferGeometry. Il ne doit pas contenir + de références aux fonctions car celles-ci ne seront pas clonées. +

Impostare `enabled` a `true` + farà riavviare l'animazione immediatamente solo se è soddisfatta la seguente condizione: + [page:.paused paused] è `false`, l'azione non è stata disattivata nel frattempo + (eseguendo un comando di [page:.stop stop] o [page:.reset reset]) e né [page:.weight weight] né + [page:.timeScale timeScale] sono pari a `0`. +

    + +

    [property:Number loop]

    +

    + La modalità di looping può essere modificata con [page:.setLoop setLoop]. L'impostazione predefinita è + [page:Animation THREE.LoopRepeat] (con un numero infinito di [page:.repetitions ripetizioni])

    + + Il valore deve essere una di queste costanti:

    + [page:Animation THREE.LoopOnce] - riproduce il clip una volta,
    + [page:Animation THREE.LoopRepeat] - riproduce il clip con il numero di `ripetizioni` prescelto, + ogni volta saltando dalla fine della clip direttamente al suo inizio,
    + [page:Animation THREE.LoopPingPong] - riproduce il clip con il numero di `ripetizioni` prescelto, + alternativamente in avanti e in indietro. +

    + +

    [property:Boolean paused]

    +

    + Impostando `paused` a `true` l'azione verrà sospesa impostando il time scale effettivo a `0`. Il valore di default è `false`. +

    + +

    [property:Number repetitions]

    +

    + Il numero di ripetizioni dell'[page:AnimationClip] eseguite nel corso di questa azione. + Può essere settato tramite [page:.setLoop setLoop]. Il valore di default è `Infinity`.

    + Se la modalità di [page:loop looping] è impostata a [page:Animation THREE.LoopOnce], impostare questo valore non ha effetti. +

    + +

    [property:Number time]

    +

    + L'ora locale di questa azione (in secondi, partendo da `0`).

    + + Il valore viene bloccato a `0...clip.duration` (in base allo stato del ciclo). Può essere scalato + rispetto al tempo globale del mixer modificando [page:.timeScale timeScale] (utilizzando + [page:.setEffectiveTimeScale setEffectiveTimeScale] o [page:.setDuration setDuration]).
    +

    + +

    [property:Number timeScale]

    +

    + Fattore di scala per il [page:.time tempo]. Un valore uguale a `0` mette in pausa l'azione. Valori + negativi fanno sì che l'animazione venga riprodotta all'indietro. Il valore di default è `1`.

    + Le proprietà/metodi relativi a `timeScale` (rispettivamente `time`) sono: + [page:.getEffectiveTimeScale getEffectiveTimeScale], + [page:.halt halt], + [page:.paused paused], + [page:.setDuration setDuration], + [page:.setEffectiveTimeScale setEffectiveTimeScale], + [page:.stopWarping stopWarping], + [page:.syncWith syncWith], + [page:.warp warp]. +

    + +

    [property:Number weight]

    +

    + Il grado di influenza di questa azione (nell'intervallo `[0, 1]`). I valori tra `0` (nessun impatto) + e 1 (impatto totale) possono essere usati per combinare più azioni. Il valore di default è `1`.

    + Le proprietà/metodi relativi a `weight` sono: + [page:.crossFadeFrom crossFadeFrom], + [page:.crossFadeTo crossFadeTo], + [page:.enabled enabled], + [page:.fadeIn fadeIn], + [page:.fadeOut fadeOut], + [page:.getEffectiveWeight getEffectiveWeight], + [page:.setEffectiveWeight setEffectiveWeight], + [page:.stopFading stopFading]. +

    + +

    [property:Boolean zeroSlopeAtEnd]

    +

    + Abilita l'interpolazione uniforme senza clip separati per inizio, loop e fine. Il valore di default è `true`. +

    + +

    [property:Boolean zeroSlopeAtStart]

    +

    + Abilita l'interpolazione uniforme senza clip separati per inizio, loop e fine. Il valore di default è `true`. +

    + + +

    Metodi

    + + +

    [method:this crossFadeFrom]( [param:AnimationAction fadeOutAction], [param:Number durationInSeconds], [param:Boolean warpBoolean] )

    +

    + Provoca il [page:.fadeIn fade in] (la dissolvenza in entrata) di questa azione, e la dissolvenza in uscita di un'altra azione + simultaneamente, entro l'intervallo passato. Questo metodo può essere concatenato.

    + + Se warpBoolean è true, verranno applicati ulteriori [page:.warp warping] (modifiche graduali delle scale temporali).

    + + Nota: Come con `fadeIn`/`fadeOut`, la dissolvenza inizia/termina con un weight di 1. +

    + +

    [method:this crossFadeTo]( [param:AnimationAction fadeInAction], [param:Number durationInSeconds], [param:Boolean warpBoolean] )

    +

    + Provoca il [page:.fadeOut fade out] (la dissolvenza in uscita) di questa azione, e la dissolvenza in entrata di un'altra azione + simultaneamente, entro l'intervallo passato. Questo metodo può essere concatenato.

    + + Se warpBoolean è true, verranno applicati ulteriori [page:.warp warping] (modifiche graduali delle scale temporali).

    + + Nota: Come con `fadeIn`/`fadeOut`, la dissolvenza inizia/termina con un weight di 1. +

    + +

    [method:this fadeIn]( [param:Number durationInSeconds] )

    +

    + Aumenta il [page:.weight weight] di questa azione gradualmente da `0` a `1`, entro l'intervallo passato. + Questo metodo può essere concatenato. +

    + +

    [method:this fadeOut]( [param:Number durationInSeconds] )

    +

    + Diminuisce il [page:.weight weight] di questa azione gradualmente da `1` a `0`, entro l'intervallo passato. + Questo metodo può essere concatenato. +

    + +

    [method:Number getEffectiveTimeScale]()

    +

    + Restituisce l'effettivo time scale (considerando lo stato attuale di [page:.warp warping] e di [page:.paused paused]). +

    + +

    [method:Number getEffectiveWeight]()

    +

    + Restituisce l'effettivo weight (considerando lo stato attuale di fading e di [page:.enabled enabled]). +

    + +

    [method:AnimationClip getClip]()

    +

    + Restituisce la clip che contiene i dati di animazione di questa azione. +

    + +

    [method:AnimationMixer getMixer]()

    +

    + Restituisce il mixer responsabile dell'esecuzione di questa azione. +

    + +

    [method:Object3D getRoot]()

    +

    + Restituisce l'oggetto root sul quale questa animazione è eseguita. +

    + +

    [method:this halt]( [param:Number durationInSeconds] )

    +

    + Decelera la velocità di questa animazione a `0` diminuendo gradualmente il [page:.timeScale timeScale] + (a partire dal valore corrente), entro l'intervallo passato. Questo metodo può essere concatenato. +

    + +

    [method:Boolean isRunning]()

    +

    + Restituisce true se il [page:.time time] dell'azione è attualmente in esecuzione.

    + + Oltre ad essere attivato nel mixer (vedi [page:.isScheduled isScheduled]) le seguenti condizioni devono essere soddisfatte: + [page:.paused paused] deve essere uguale a false, [page:.enabled enabled] deve essere uguale a true, + [page:.timeScale timeScale] deve essere diversa da `0`, e non deve essere prevista nessuna programmazione + per un avvio ritardato ([page:.startAt startAt]).

    + + Nota: il fatto che `isRunning` sia true non significa necessariamente che l'animazione sia effettivamente visibile. + Ciò avviene solo se [page:.weight weight] è impostato su un valore diverso da zero. +

    + +

    [method:Boolean isScheduled]()

    +

    + Restituisce true se questa azione è attivata nel mixer.

    + Nota: Questo non significa necessariamente che l'animazione sia effettivamente in esecuzione (confronta + le condizioni aggiuntive per [page:.isRunning isRunning]). +

    + +

    [method:this play]()

    +

    + Dice al mixer di attivare l'azione. Questo metodo può essere concatenato.

    + + Nota: Attivare questa azione non significa necessatiamente che l'animazione verrà avviata immediatamente: + Se l'azione era già terminata prima (raggiungendo la fine del suo ultimo loop), o se è stato impostato un tempo + per un inizio ritardato (tramite [page:.startAt startAt]), prima deve essere eseguito un [page:.reset reset]. + Anche altre impostazioni, (come [page:.paused paused]=true, [page:.enabled enabled]=false, + [page:.weight weight]=0, [page:.timeScale timeScale]=0) possono impedire la riproduzione dell'animazione. +

    + +

    [method:this reset]()

    +

    + Reimposta l'azione. Questo metodo può essere concatenato.

    + + Questo metodo imposta [page:.paused paused] a false, [page:.enabled enabled] a true, + [page:.time time] a `0`, interrompe ogni fading e wraping programmati, e rimuove il conteggio del loop + interno per l'avvio ritardato.

    + + Nota: .`reset` è sempre chiamato da [page:.stop stop], ma .`reset` non chiama .`stop`. + Questo significa che se vuoi chiamare entrambi i metodi, non chiamare .`reset`, chiama invece .`stop`. +

    + +

    [method:this setDuration]( [param:Number durationInSeconds] )

    +

    + Imposta la durata per un singolo loop dell'azione (regolando il [page:.timeScale timeScale] e + interrompendo qualsiasi warping programmato). Questo metodo può essere concatenato. +

    + +

    [method:this setEffectiveTimeScale]( [param:Number timeScale] )

    +

    + Imposta il [page:.timeScale timeScale] e interrompe qualsiasi warping programmato. Questo metodo può essere concatenato.

    + + Se [page:.paused paused] è false, l'effettivo time scale (una proprietà interna) sarà impostato a questo valore, + altrimenti il time scale effettivo (che influenza direttamente l'animazione in questo momento) verrà impostato a `0`.

    + + Nota: Se .`timeScale` è impostato `0` da questo metodo, .`paused` non verrà impostato automaticamente a `true`. +

    + +

    [method:this setEffectiveWeight]( [param:Number weight] )

    +

    + Imposta il [page:.weight weight] e interrompe qualsiasi fading programmato. Questo metodo può essere concatenato.

    + + Se [page:.enabled enabled] è true, l'effettivo weight (una proprietà interna) sarà impostato a questo valore, + altrimenti il weight effettivo (che influenza direttamente l'animazione in questo momento) verrà impostata a `0`.

    + + Nota: Se .`weight` è impostato `0` da questo metodo, .`enabled` non passerà automaticamente a `false`. +

    + +

    [method:this setLoop]( [param:Number loopMode], [param:Number repetitions] )

    +

    + Imposta la modalità di [page:.loop looping] e il numero di [page:.repetitions ripetizioni]. Questo metodo può essere concatenato. +

    + +

    [method:this startAt]( [param:Number startTimeInSeconds] )

    +

    + Definisce il tempo per un avvio ritardato (solitamente passato come [page:AnimationMixer.time] + + deltaTimeInSeconds). Questo metodo può essere concatenato.

    + + Nota: L'animazione inizierà solo all'ora indicata se .`startAt` è concatenato con + [page:.play play], o se l'azione è già stata attivata nel mixer (da una precedente chiamata di .`play`, + senza che nel frattempo sia stata fermata o resettata). +

    + +

    [method:this stop]()

    +

    + Dice al mixer di disattivare questa azione. Questo metodo può essere concatenato.

    + + L'azione verrà immediatamente interrotta e completamente [page:.reset resettata].

    + + Nota: puoi interrompere tutte le azioni attive sullo stesso mixer in una volta sola tramite + [page:AnimationMixer.stopAllAction mixer.stopAllAction]. +

    + +

    [method:this stopFading]()

    +

    + Interrompe qualsiasi [page:.fadeIn fading] programmato applicato a questa azione. Questo metodo può essere concatenato. +

    + +

    [method:this stopWarping]()

    +

    + Interrompe qualsiasi [page:.warp warping] programmato applicato a questa azione. Questo metodo può essere concatenato. +

    + +

    [method:this syncWith]( [param:AnimationAction otherAction] )

    +

    + Sincronizza questa azione con l'altra azione passata. Questo metodo può essere concatenato.

    + + La sincronizzazione viene fatta impostando i valori [page:.time time] e [page:.timeScale timeScale] + di questa azione ai corrispondenti valori dell'altra azione (interrompendo qualsiasi warping programmato).

    + + Nota: Le modifiche future di `time` e `timeScale` dell'altra azione non verranno rilevate. +

    + +

    [method:this warp]( [param:Number startTimeScale], [param:Number endTimeScale], [param:Number durationInSeconds] )

    +

    + Modifica la velocità di riproduzione, entro l'intervallo di tempo passato, modificando + gradualmente il [page:.timeScale timeScale] da `startTimeScale` a `endTimeScale`. Questo metodo può essere concatenato. +

    + + +

    Eventi

    + + +

    + Ci sono due eventi che indicano quando un singolo ciclo dell'azione o l'intera azione è terminata. Si può rispondere ad essi con: +

    + + mixer.addEventListener( 'loop', function( e ) { …} ); // properties of e: type, action and loopDelta + mixer.addEventListener( 'finished', function( e ) { …} ); // properties of e: type, action and direction + + +

    [name]

    + +

    + Un KeyframeTrack è una sequenza temporizzata di [link:https://en.wikipedia.org/wiki/Key_frame keyframe], + composti da una lista di tempi e valori correlati, utilizzati per animare una proprietà specifica di un oggetto. +

    + +

    + Per una paronamica dei diversi elementi del sistema di animazione di three.js consultare l'articolo + "Sistema di animazione" nella sezione "Prossimi Passi" del manuale. +

    + +

    + A differenza della gerarchia di animazione del [link:https://github.com/mrdoob/three.js/wiki/JSON-Model-format-3 modello JSON], + `KeyframeTrack` non memorizza i suoi singoli keyframe come oggetti in un array "keys" (che contiene i tempi + e i valori di ciascun frame in un unico posto). +

    + +

    + Invece ci sono sempre due array in un `KeyframeTrack`: l'array [page:.times times] + memorizza i valori temporali per tutti i keyframe di questa traccia in ordine sequenziale e l'array + [page:.values values] contiene i corrispondenti valori di modifica della proprietà animata. +

    + +

    + Un singolo valore, appartenente ad un determinato momento, non può essere solo un semplice numero, ma + (per esempio) un vettore (se una posizione è animata) o un quaternione (se una rotazione è animata). + Per questo motivo l'array values (che è anche un array flat) potrebbe essere tre o quattro volte + più lungo dell'array times. +

    + +

    + In corrispondenza dei diversi tipi possibili di valori animati esistono diverse sottoclassi di `KeyframeTrack`, + che ereditano la maggior parte delle proprietà e dei metodi: +

    + +
      +
    • [page:BooleanKeyframeTrack]
      • +
    • [page:ColorKeyframeTrack]
      • +
    • [page:NumberKeyframeTrack]
      • +
    • [page:QuaternionKeyframeTrack]
      • +
    • [page:StringKeyframeTrack]
      • +
    • [page:VectorKeyframeTrack]
      • +
    + +

    + Alcuni esempi di come creare manualmente [page:AnimationClip AnimationClip] con diversi tipi di + KeyframeTrack possono essere trovati nel file [link:https://threejs.org/examples/jsm/animation/AnimationClipCreator.js AnimationClipCreator]. +

    + +

    + Poiché i valori espliciti sono solo specifici per i punti temporali discreti memorizzati nell'array times + tutti i valori itermedi devono essere interpolati. +

    + +

    + Il nome della track è importante per il collegamento di questa track con una proprietà specifica + del nodo animato (creato da [page:PropertyBinding]). +

    + + +

    Costruttore

    + + +

    [name]( [param:String name], [param:Array times], [param:Array values], [param:Constant interpolation] )

    +

    + [page:String name] - l'identificativo per `KeyframeTrack`.
    + [page:Array times] - un array di times di keyframe, convertito internamente a + [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Float32Array Float32Array].
    + [page:Array values] - un array con i valori relativi all'array times, convertito internamente a + [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Float32Array Float32Array].
    + [page:Constant interpolation] - il tipo di interpolazione da usare. Vedi + [page:Animation Animation Constants] per i possibili valori. L'impostazione predefinita è [page:Animation InterpolateLinear]. +

    + + +

    Proprietà

    + + +

    [property:String name]

    +

    + Il nome della track può riferirsi a morph targets o [page:SkinnedMesh bones] o possibilmente ad altri valori all'interno dell'oggetto animato. + Vedi [page:PropertyBinding.parseTrackName] per le forme di stringhe che possono essere parsate per il property + binding: +

    + +

    + Il nome può specificare il nodo utilizzando il suo nome o il suo uuid (anche se deve trovarsi + nel sottoalbero del nodo del grafo della scena passato al mixer). Oppure, se il nome della track inizia con un punto, + la track si applica al nodo root che è stato passato nel mixer. +

    + +

    + Solitamente dopo il nodo una proprietà viene specificata direttamente. Ma si può anche specificare + una sottoproprietà, come .rotation[x], se si vuole guidare il componente X della rotazione tramite + una traccia float. +

    + +

    + Si possono anche specificare ossa (bones) o multimateriali usando il nome di un oggetto, per esempio: + .bones[R_hand].scale; il canale rosso del colore diffuso del quarto materiale in un array di materiali + - come ulteriore esempio - è accessibile con .materials[3].diffuse[r]. +

    + +

    + Il PropertyBinding risolverà anche i nomi dei morph target, per esempio: .morphTargetInfluences[run]. +

    + +

    + Nota: Il nome della traccia non deve essere per forza univoco. Più tracce possono guidare la stessa proprietà. + Il risultato deve essere basato su una miscela ponderata tra le tracce multiple in base ai pesi delle rispettive + azioni. +

    [name]

    + +

    + Questa classe memorizza i dati per un attributo (come le posizioni dei vertici, gli indici delle facce, le normali, + i colori, le coordinate UV e alcuni attributi personalizzati) associato ad una [page:BufferGeometry], + che consente un passaggio più efficiente dei dati alla GPU. Consulta questa pagina per i dettagli ed un esempo di + utilizzo. Quando si lavora con dati di tipo vettoriale, i metodi helper .fromBufferAttribute( attribute, index ) + sulle classi [page:Vector2.fromBufferAttribute Vector2], + [page:Vector3.fromBufferAttribute Vector3], + [page:Vector4.fromBufferAttribute Vector4] e [page:Color.fromBufferAttribute Color] possono essere utili. +

    + +

    Costruttore

    +

    [name]( [param:TypedArray array], [param:Integer itemSize], [param:Boolean normalized] )

    +

    + [page:TypedArray array] -- Deve essere un [link:https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/TypedArray TypedArray]. + Utilizzato per istanziare il buffer.
    + Questo array dovrebbe avere gli elementi itemSize * numVertices + dove numVertices è il numero di vertici della [page:BufferGeometry BufferGeometry] associata.

    + + [page:Integer itemSize] -- il numero di valori dell'array che deve essere associato ad un particolare vertice. + Per esempio, se questo atttibuto memorizza un vettore a 3 componenti (come posizione, normale o colore), + itemSize dovrebbe essere 3.

    + + [page:Boolean normalized] -- (opzionale) Si applica solo ai dati interi. Indica il modo in cui i dati sottostanti + del buffer si adattano ai valori del codice GLSL. Ad esempio, se l'[page:TypedArray array] è un'istanza di UInt16Array, + e [page:Boolean normalized] è a true, i valori `0 - +65535` nei dati dell'array saranno mappati su 0.0f - +1.0f nell'attributo GLSL. + Un Int16Array (con segno) sarà mappato da -32768 - +32767 a -1.0f - +1.0f. Se [page:Boolean normalized] è a false, i valori + verranno convertiti in float non modificati, p.e. 32767 diventa 32767.0f. +

    + +

    + + Può essere utilizzato solo per aggiornare alcuni componenti dei vettori memorizzati (per esempio, solo + il componente relativo al colore). +

    + +

    [property:Usage usage]

    +

    + Definisce il modello di utilizzo previsto per l'archivio dati a fini di ottimizzazione. Corrisponde al paramentro `usage` + di [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/bufferData WebGLRenderingContext.bufferData](). + Il valore predefinito è [page:BufferAttributeUsage StaticDrawUsage]. Vedi le [page:BufferAttributeUsage costanti] di utilizzo + per tutti i valori possibili.

    + +

    + Una rappresentazione della geometria di mesh, di linee o di punti. Include posizioni di vertici, indici della faccia, + normali, colori, coordinate UV, e attributi personalizzati all'interno dei buffer, riducendo il costo del passaggio + di tutti questi dati alla GPU. +

    Costruttore

    + + +

    [name]()

    +
    + Crea un nuovo [name]. Inoltre imposta alcune proprietà al valore predefinito. +
    + + +

    Proprietà

    + +

    [property:Object attributes]

    +

    + Questo hashmap ha come id il nome dell'attributo da impostare e come valore il [page:BufferAttribute buffer] su cui impostarlo. + Piuttosto che accedere a questa proprietà direttamente, usa [page:.setAttribute] e [page:.getAttribute] per accedere agli attributi + della geometria. +

    + +

    [property:Box3 boundingBox]

    +

    + Bounding box per la bufferGeometry, che può essere calcolato con + [page:.computeBoundingBox](). Il valore predefinito è `null`. +

    + +

    [property:Sphere boundingSphere]

    +

    + Bounding sphere per la bufferGeometry, che può essere calcolato con + [page:.computeBoundingSphere](). Il valore predefinito è `null`. +

    + +

    [property:Object drawRange]

    +

    + Determina la parte della geometria da visualizzare. Non dovrebbe essere impostato + direttamente, usa invece [page:.setDrawRange]. Il valore predefinito è + + { start: 0, count: Infinity } + + Per la BufferGeometry non indicizzata, count è il numero di vertici da visualizzare. + Per la BufferGeometry indicizzata, count è il numero di indici da visualizzare. +

    + +

    [property:Array groups]

    +

    + Divide la geometria in gruppi, ognuno dei quali verrà renderizzato in una chimata draw WebGL separata. + Ci permette che un array di materiali venga usato con una geometria.

    + + Ogni gruppo è un oggetto della forma: + { start: Integer, count: Integer, materialIndex: Integer } + dove start specifica il primo elemento nella chiamata draw - il primo vertice per la geometria non + indicizzata, altrimenti il primo indice del triangolo. Count specifica quanti vertici (o indici) sono + inclusi, e materialIndex specifica l'indice dell'array del materiale da utilizzare.

    + + Usa [page:.addGroup] per aggiungere gruppi, piuttosto che modificare questo array direttamente.

    + + Ogni vertice e indice deve appartenere esattamente ad un gruppo - i gruppi non devono condividere vertici o + indici, e non devono lasciare vertici o indici inutilizzati. +

    + + + + + +

    [property:Integer id]

    +

    Numero univoco per questa istanza della bufferGeometry.

    + +

    [property:BufferAttribute index]

    +

    + Consente di riutilizzare i vertici su più triangoli; viene chiamato "indexed triangles". + Ogni triangolo è associato con gli indici di tre vertici. Questo attributo quindi memorizza + l'indice di ogni vertice per ogni faccia del triangolo. + + Se questo attributo non è impostato, il [page:WebGLRenderer renderer] assume che ogni 3 posizioni contigue + rappresentano un singolo triangolo. + + Il valore predefinito è `null`. +

    + +

    [property:Boolean isBufferGeometry]

    +

    + Flag di sola lettura per verificare se un dato oggetto è di tipo [name]. +

    + +

    [property:Object morphAttributes]

    +

    + Hashmap di BufferAttribute contenente i dettagli dei target morph delle geometrie.
    + Nota: Una volta che la geometria è stata renderizzata, i dati dell'attributo morph non possono essere modificati. + Dovrai chiamare [page:.dispose](), e creare una nuova istanza della [name]. +

    + +

    [property:Boolean morphTargetsRelative]

    +

    + Usato per controllare il comportamento del target morph: quando è impostato a true, i dati del target morph vengono + trattati come offset relativi, anziché come posizioni/normali assoluti. + + L'impostazione predefinita è `false`. +

    + +

    [property:String name]

    +

    + Nome opzionale per questa istanza di bufferGeometry. Il valore predefinito è una stringa vuota. +

    + +

    [property:Object userData]

    +

    + Un oggetto che può essere utilizzato per memorizzare i dati relativi alla BufferGeometry. + Non dovrebbe contenere i riferimenti alle funzioni poiché queste non verranno clonate. +

    + +

    [property:String uuid]

    +

    + [link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] di questa istanza. + Viene assegnato automaticamente e non deve essere modificato. +

    + +

    + Flag di sola lettura per controllare se un dato oggetto è di tipo [name]. +

    + +

    [property:Layers layers]

    +

    + Il layer di appartenenza dell'oggetto. L'oggetto è visibile solo se ha al più un layer in comune + con la [page:Camera telecamera] utilizzata. Questa proprietà può anche essere utilizata per filtrare + gli oggetti non voluti nell'intersezione di test del reycasting quando si usa il [page:Raycaster]. +

    + +

    [property:Matrix4 matrix]

    +

    La matrice di trasformazione locale.

    + +

    [property:Boolean matrixAutoUpdate]

    +

    + Quando viene settato calcola la matrice di posizione, (rotazione o quaternione) e + ridimensiona ogni fotogramma ed inoltre ricalcola la proprietà matrixWorld. L'impostazione predefinita è [page:Object3D.DEFAULT_MATRIX_AUTO_UPDATE] (true). +

    +

    Nome opzionale dell'oggetto (non è necessario che sia univoco). Il valore predefinito è una stringa vuota.

    + +

    [property:Matrix3 normalMatrix]

    +

    + Questo viene passato allo shader e utilizzato per calcolare l'illuminazione per l'oggetto. + È la trasposizione dell'inverso della sottomatrice 3x3 in alto a sinistra di modelViewMatrix di questo oggetto.

    + + Il motivo di questa matrice speciale è che il semplice utilizzo della matrice modelViewMatrix potrebbe causare una lunghezza non unitaria delle normali + (in caso di scalatura) o una direzione non perpendicolare (in caso di scalatura non uniforme).

    + + Dall'altra parte, la parte di traslazione della matrice modelViewMatrix non è rilevante per il calcolo delle normali. Quindi una Matrix3 è sufficiente. +

    + +

    [property:Function onAfterRender]

    +

    + Una callback opzionale che viene eseguita immediatamente dopo che un oggetto 3D è stato renderizzato. + Questa funzione è chiamata con i seguenti parametri: renderer, scene, camera, geometry, material, group. +

Ovvero oggetti 3D che definiscono + il loro aspetto visivo con geometrie e materiali come istanze di [page:Mesh], [page:Line], [page:Points] o [page:Sprite]. + Invece, le istanze di [page:Object3D], [page:Group] o [page:Bone] non sono renderizzabili e quindi questa callback non viene eseguita su questi oggetti. +

    + +

    [property:Function onBeforeRender]

    +

    + Una callback opzionale che viene eseguita immediatamente prima che un oggetto 3D è stato renderizzato. + Questa funzione è chiamata con i seguenti parametri: renderer, scene, camera, geometry, material, group. +

    +

Ovvero oggetti 3D che definiscono + il loro aspetto visivo con geometrie e materiali come istanze di [page:Mesh], [page:Line], [page:Points] o [page:Sprite]. + Invece, le istanze di [page:Object3D], [page:Group] o [page:Bone] non sono renderizzabili e quindi questa callback non viene eseguita su questi oggetti. +

    + +

    [property:Object3D parent]

    +

    Genitore dell'oggetto nel [link:https://en.wikipedia.org/wiki/Scene_graph grafo della scena]. Un oggetto può avere più + di un genitore.

    + +

    [property:Vector3 position]

    +

    Un [page:Vector3] che rappresenta la posizione locale dell'oggetto. Il valore predefinito è `(0, 0, 0)`.

    + +

    [property:Number renderOrder]

    +

    + Questo valore consente di sovrascrivere l'ordine di rendering predefinito degli oggetti del [link:https://en.wikipedia.org/wiki/Scene_graph grafico di scena] + sebbene gli oggetti opachi e trasparenti rimangano ordinati in modo indipendente. Quando questa proprietà viene impostata per un'istanza di [page:Group Group], + tutti gli oggetti discendenti saranno ordinati e renderizzati insieme. + L'ordinamento è dal più piccolo al più grande renderOrder. Il valore predefinito è `0`. +

    + +

    [property:Euler rotation]

    +

    + La rotazione locale dell'oggetto (vedi [link:https://en.wikipedia.org/wiki/Euler_angles gli angoli di Eulero]), in radianti. +

    + +

    [property:Vector3 scale]

    +

    + La scala locale dell'oggetto. Il valore predefinito è [page:Vector3]( 1, 1, 1 ). +

    + +

    [property:Vector3 up]

    +

    + Questa proprietà viene utilizzata dal metodo [page:.lookAt lookAt], per esempio, per determinare l'orientamento del risultato.
    + L'impostazione predefinita è [page:Object3D.DEFAULT_UP] - che è, `( 0, 1, 0 )`. +

    + +

    [property:Object userData]

    +

    + Un oggetto che può essere utilizzato per memorizzare i dati personalizzati di un Object3D. + Non dovrebbe contenere riferimenti a funzioni poiché queste non verranno clonate. +

    L'oggetto viene visualizzato se `true`. Il valore predefinito è `true`.

    + + + + +

    Proprietà Statiche

    +

    + Le proprietà statiche e i metodi sono definiti per classe piuttosto che per istanza della classe. + Questo significa che modificando [page:Object3D.DEFAULT_UP] o [page:Object3D.DEFAULT_MATRIX_AUTO_UPDATE] + verranno modificati i valori di [page:.up up] e [page:.matrixAutoUpdate matrixAutoUpdate] per `ogni` + istanza di Object3D (o classi derivate) creata dopo che la modifica è stata fatta + (gli Object3D già creati non saranno interessati). +

    + +

    [property:Vector3 DEFAULT_UP]

    +

    + La direzione predefinita di [page:.up up] per gli oggetti, utilizzata anche come posizione predefinita per [page:DirectionalLight], + [page:HemisphereLight] e [page:Spotlight] (che crea luci che brillano dall'alto verso il basso).

    +

    + Un oggetto con le seguenti proprietà: + + +{ + Mesh: {}, + Line: { threshold: 1 }, + LOD: {}, + Points: { threshold: 1 }, + Sprite: {} +} + + + Dove threshold è la precisione del raycaster quando intercetta gli oggetti, in unità di world. +

    Tipi Uniform

    + +

    + Ogni uniform deve avere una proprietà `value`. Il tipo di value deve corrispondere al tipo + della variabile uniform nel codice GLSL come specificato per i tipi primitivi GLSL nella tabella + sotto. Anche le strutture uniform e gli array sono supportati.

    Uniform Strutturate

    + +

    + A volte vuoi organizzare le uniform come `structs` nel tuo codice shader. + È necessario utilizzare lo stile seguente in modo che three.js sia in grado di elaborare dati strutturati uniform. +

    + + uniforms = { + data: { + value: { + position: new Vector3(), + direction: new Vector3( 0, 0, 1 ) + } + } + }; + + Questa definizione può essere mappata con il seguente codice GLSL: + + struct Data { + vec3 position; + vec3 direction; + }; + + uniform Data data; + + +

    Uniforms Strutturate con Array

    + +

    + È anche possibile gestire `structs` negli array. La sintassi per questo caso d'uso appare così: +

    + + const entry1 = { + position: new Vector3(), + direction: new Vector3( 0, 0, 1 ) + }; + const entry2 = { + position: new Vector3( 1, 1, 1 ), + direction: new Vector3( 0, 1, 0 ) + }; + + uniforms = { + data: { + value: [ entry1, entry2 ] + } + }; + + Questa definizione può essere mappata con il seguente codice GLSL: + + struct Data { + vec3 position; + vec3 direction; + }; + + uniform Data data[ 2 ]; + + +

    + Una luce che viene emessa in una direzione specifica. Questa luce si comporterà come se + fosse infinitamente lontana e i raggi da essa prodotti fossero tutti paralleli. Il + caso d'uso comune di questa luce è simulare la luce del giorno; il sole è abbastanza lontano + che la sua posizione può essere considerata infinita, e tutti i raggi di luce + che ne provengono sono paralleli.

    + + Questa luce può proiettare le ombre - vedi la pagina [page:DirectionalLightShadow] per i dettagli. +

    + +

    Una nota riguardo la posione, il target e la rotazione

    +

    + Un punto di confusione comune per le luci direzionali è che l'impostazione della rotazione non ha alcun effetto. + Questo succede perché la DirectionalLight di three.js è l'equivalente di ciò che viene spesso chiamato + 'Target Direct Light' in altre applicazioni.

    + + Questo significa che la sua direzione viene calcolata puntando dalla [page:Object3D.position posizione] della luce + alla posizione del [page:.target target] (al contrario di una 'Free Direct Light' che ha solo una componente di rotazione).

    + + La ragione di ciò è consentire alla luce di proiettare ombre - la telecamera delle [page:.shadow ombre] + ha bisogno di una posizione da cui calcolare le ombre.

    + + Vedi la proprietà [page:.target target] di seguito per i dettagli sull'aggiornamento del target. +

    + +

    + + + // Luce bianca direzionale a metà intensità che brilla dall'alto. + const directionalLight = new THREE.DirectionalLight( 0xffffff, 0.5 ); + scene.add( directionalLight ); + + +

    [name]

    + +

    + Le sonde luminose sono un metodo alternativo di aggiungere luce in una scena 3D. Diversamente dalle classiche sorgenti + di luce (ad esempio, direzionali, puntiformi o luci spot), le sonde luminose non emettono luce. Invece memorizzano + informazioni sulla luce che passa attraverso lo spazio 3D. Durante il rendering, la luce che colpisce un + oggetto 3D viene approssimata utilizzando i dati della sonda di luce. +

    + +

    + Le sonde luminose vengono solitamente create da mappe ambientali (di radianza). La classe [page:LightProbeGenerator] + può essere utilizzata per create le sonde luminose dalle istanze di [page:CubeTexture] o [page:WebGLCubeRenderTarget]. + Tuttavia, i dati di stima della luce potrebbero essere forniti in altre forme, ad es. di WebXR. Ciò consente il + rendering di realtà aumentata che reagiscono all'illuminazione del mondo reale. +

    + +

    + L'attuale implementazione della sonda in three.js supporta le cosidette sonde a luce diffusa. Questo tipo + di sonda luminosa è funzionalmente equivalente a una mappa ambientale di irradianza. +

    + [page:Camera camera] - la visione del mondo da parte della luce.

    + + Crea una nuova [name]. Questa classe non deve essere chiamata direttamente - viene usata come classe base + da altre ombre di luce. +

    + +

    Proprietà

    + +

    [property:Boolean autoUpdate]

    +

    + Abilita gli aggiornamenti automatici dell'ombra della luce. Il valore predefinito è `true`. + Se non hai bisogno di luci/ombre, puoi impostarlo su `false`. +

    + +

    [property:Camera camera]

    +

    + La visione del mondo da parte della luce. Viene utilizzata per generare un mappa di profondità della scena; + gli oggetti dietro ad altri oggetti dalla prospettiva della luce saranno in ombra. +

    + +

    [property:Float bias]

    +

    + Bias della mappa delle ombre, quanto aggiungere o sottrarre dalla profondità normalizzata quando si decide se una superficie è in ombra.
    + Il valore predefinito è 0. Piccole regolazioni qui (nell'ordine di 0,0001) possono aiutare a ridurre gli artefatti nelle ombre. +

    + +

    [property:Integer blurSamples]

    +

    + La quantità di campioni da utilizzare durante la sfocatura di una mappa ombra VSM. +

    + +

    [property:WebGLRenderTarget map]

    +

    + La mappa di profondità generata usando la telecamera interna; una posizione oltre la profondità di un pixel è in ombra. + Calcolato internamente durante il rendering. +

    + +

    [property:WebGLRenderTarget mapPass]

    +

    + La mappa di distribuzione generata usando la telecamera interna; un'occlusione viene calcolata in base alla distribuzione + della profondità. Calcolato internamente durante il rendering. +

    + +

    [property:Vector2 mapSize]

    +

    + Un [Page:Vector2] che definisce la larghezza e l'altezza della mappa dell'ombra.

    + + Valori più alti danno una maggior qualità alle ombre a scapito del tempo di calcolo. I valori + devono essere potenze di 2, fino a [page:WebGLRenderer.capabilities].maxTextureSize per un determinato + dispositivo, sebbene la larghezza e l'altezza non debbano essere le stesse (quindi, per esempio (512, 1024) + è valido). Il valore predefinito è *( 512, 512 )*. +

    + +

    [property:Matrix4 matrix]

    +

    + Modello per lo spazio delle ombre della telecamera, per calcolare la posizione e la profondità nella mappa delle ombre. + Memorizzato in una [page:Matrix4 Matrix4]. Questa viene calcolata internamente durante il rendering. +

    + +

    [property:Boolean needsUpdate]

    +

    + Quando viene impostato a `true`, le mappe d'ombra saranno aggiornate nella successiva chiamata del `render`. + L'impostazione predefinita è `false`. + Se si è impostato [page:.autoUpdate] a `false`, sarà necessario impostare questa proprietà su `true` e quindi + eseguire una chiamata di rendering per aggiornare l'ombra della luce. +

    + +

    [property:Float normalBias]

    +

    + Definisce di quanto la posizione utilizzata per interrogare la mappa delle ombre è sfalsata rispetto + alla normale dell'oggetto. Il valore predefinito è 0. Aumentando questo valore si può ridurre l'acne dell'ombra, + soprattutto nelle scene di grandi dimensioni in cui la luce illumina la geometria con un angolo poco profondo. + Il costo è che le ombre possono apparire distorte. +

    + +

    [property:Float radius]

    +

    + Impostando questo valore maggiore di 1 si sfocheranno i bordi dell'ombra.
    + + Valori alti causeranno degli effetti di banding indesiderati nelle ombre - un [page:.mapSize mapSize] + maggiore consentirà di utilizzare un valore più elevato qui prima che questi effetti diventino visibili.
    + Se [page:WebGLRenderer.shadowMap.type] è impostato a [page:Renderer PCFSoftShadowMap], il raggio non ha effetto e + si consiglia di aumentare la morbidezza diminuendo invece [page:.mapSize mapSize].

    + + Si noti che questo non ha effetto se [page:WebGLRenderer.shadowMap.type] è impostato a [page:Renderer BasicShadowMap]. +

    + + +

Se il server non imposta l'header Content-Length; .[page:Integer total] sarà 0.
    +

    +

    + Questo metodo è equivalente a [page:.load], ma restituisce una [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise Promise]. +

    +

    + [page:Function onLoad] è gestito da [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/resolve Promise.resolve] + e [page:Function onError] è gestito da [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/reject Promise.reject]. +

    + +

    [method:undefined parse]()

    +

    + Questo metodo deve essere implementato da tutti i loader concreti. Contiene la logica per il parsing della risorsa nelle entità di three.js. +

    + +

    [method:this setCrossOrigin]( [param:String crossOrigin] )

    +

    + [page:String crossOrigin] — La stringa crossOrigin per implementare il CORS per caricare la url da un dominio diverso che permette il CORS. +

    + +

    [method:this setWithCredentials]( [param:Boolean value] )

    +

    + Indica se XMLHttpRequest utilizza le credenziali come cookie, header di autorizzazione o + certificati client TLS. Vedi [link:https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/withCredentials XMLHttpRequest.withCredentials].
    + Si noti che non ha effetti se stai caricando file localmente o dallo stesso dominio. +

    + +

    [method:this setPath]( [param:String path] )

    +

    + [page:String path] — Imposta il percorso base per la risorsa. +

    + +

    [method:this setResourcePath]( [param:String resourcePath] )

    +

    + [page:String resourcePath] — Imposta il percorso base per le risorse dipendenti come le texture. +

    + +

    [method:this setRequestHeader]( [param:Object requestHeader] )

    +

    + [page:Object requestHeader] - key: Il nome dell'header il cui valore deve essere impostato; value: Il valore da impostare come corpo dell'header.

    + + Imposta l'[link:https://developer.mozilla.org/en-US/docs/Glossary/Request_header header della richiesta] utilizzato nella richiesta HTTP. +

    + Il valore predefinito è `1.0`. +

    + +

    [property:Boolean polygonOffset]

    + Definisce se questo materiale è trasparente. Ciò a effetto sul rendering + poiché gli oggetti trasparenti richiedono un trattamento speciale e vengono + visualizzati dopo gli oggetti non trasparenti.
    + Quando impostato a true, la misura in cui il materiale è trasparente è controllata impostando + la sua proprietà di [page:Float opacity].
    + Il valore predefinito è `false`. +

    + +

    [property:String type]

    +

    + Il valore è la stringa 'Material'. Non può essere cambiato, e può essere utilizzato + per trovare tutti gli oggetti di questo tipo nella scena. +

    + +

    [property:String uuid]

    +

    + [link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] di questa istanza di materiale. + Questo viene assegnato automaticamente, quindi non dovrebbe essere modificato. +

    Metodi

    + +

    I metodi [page:EventDispatcher EventDispatcher] sono disponibili in questa classe.

    + +

    [method:Material clone]( )

    +

    Restituisce un nuovo materiale con gli stessi parametri di questo materiale.

    + +

    [method:this copy]( [param:material material] )

    +

    Copia i parametri dal materiale passato in questo materiale.

    + +

    [method:undefined dispose]()

    +

    + Libera le risorse relative alla GPU allocate da questa istanza. + Chiama questo metodo ogni volta che questa istanza non è più utilizzata nella tua app.

    + + Le texture del materiale devono essere liberate dal metodo dispose() della [page:Texture Texture]. +

    + +

    [method:undefined onBeforeCompile]( [param:Shader shader], [param:WebGLRenderer renderer] )

    +

    + Una callback opzionale che viene eseguita immediatamente prima che il programma shader sia compilato. + Questa funzione viene chiamata con il codice sorgente dello shader come parametro. + Utile per la modifica di materiali build-in. +

    +

    + A differenza delle proprietà, la callback non è supportata da [page:Material.clone .clone](), [page:Material.copy .copy]() e [page:Material.toJSON .toJSON](). +

    + +

    [method:String customProgramCacheKey]()

    +

    + Nel caso in cui onBeforeCompile sia utilizzato, questa callback può essere utilizzata per identificare i valori delle impostazioni utilizzati + nel onBeforeCompile, quindi three.js può riutilizzare uno shader memorizzato nella cache o ricompilare lo shader per questo materiale secondo + necessità. +

    + +

    + Per esempio, se onBeforeCompile contiene un'istruzione condizionale come:
    + + if ( black ) { + + shader.fragmentShader = shader.fragmentShader.replace('gl_FragColor = vec4(1)', 'gl_FragColor = vec4(0)') + + } + + + allora customProgramCacheKey deve essere impostato come questo:
    + + material.customProgramCacheKey = function() { + + return black ? '1' : '0'; + + } + + +

    + +

    + A differenza delle proprietà, la callback non è supportata da [page:Material.clone .clone](), [page:Material.copy .copy]() e [page:Material.toJSON .toJSON](). +

    + +

    [method:undefined setValues]( [param:Object values] )

    +

    + values -- un contenitore con i parametri.
    + Imposta le proprietà in base ai `values`. +

    + +

    [method:Object toJSON]( [param:Object meta] )

    +

    + meta -- oggetto contenente metadati come texture o immagini per il materiale.
    + Converte il materiale nel [link:https://github.com/mrdoob/three.js/wiki/JSON-Object-Scene-format-4 formato JSON Object/Scene] di three.js. +

    + +

    + Un'estenzione della classe [page:MeshStandardMaterial], che fornisce proprietà di rendering basate sulla fisica più avanzate: +

    + +
      +
    • + Clearcoat (rivestimento trasparente): Alcuni materiali - come vernici per auto, fibra di carbonio + e superfici bagnate - richiedono uno strato trasparente e riflettente sopra un altro strato che può essere irregolare + o ruvido. Il rivestimento trasparente approssima questo effetto, senza la necessità di una superficie + trasparente separata. +
      • +
    • + Physically-based transparency (trasparenza fisica): Una limitazione di [page:Material.opacity .opacity] + è che materiali molto trasparenti sono meno riflettenti. La [page:.transmission] fisica + fornisce una opzione più realistica per superfici sottili e trasparenti come il vetro. +
      • +
    • + Advanced reflectivity (riflettività avanzata): Riflettività più flessibile per materiali non metallici. +
      • +
    • + Sheen: Can be used for representing cloth and fabric materials. +
      • +
    + +

    + Come risultato di queste complesse caratteristiche di ombreggiatura, MeshPhysicalMaterial + ha un elevato costo di prestazioni, per pixel, rispetto ad altri materiali utilizzati in three.js. + Molti effetti sono disabilitati per impostazione predefinita, e viene aggiunto un costo quando questi + vengono abilitati. Per ottenere risultati ottimali, specificare sempre una [page:.envMap mappa ambientale] + quando si usa questo materiale. +

    + +

    + Un materiale standard a base fisica, che utilizza il flusso di lavoro Metallic-Roughness.

    + + Physically based rendering (PBR) è recentemente diventato uno standard in molte applicazioni 3D, come + [link:https://blogs.unity3d.com/2014/10/29/physically-based-shading-in-unity-5-a-primer/ Unity], + [link:https://docs.unrealengine.com/latest/INT/Engine/Rendering/Materials/PhysicallyBased/ Unreal] e + [link:http://area.autodesk.com/blogs/the-3ds-max-blog/what039s-new-for-rendering-in-3ds-max-2017 3D Studio Max].

    + + Questo approccio differisce da quelli precedenti per il fatto che, invece di utilizzare le approssimazioni + per il modo in cui la luce interagisce con una superficie, viene utilizzato un modello fisicamente corretto. + L'idea è che, invece di modificare i materiali per ottenere un buon risultato con un'illuminazione + specifica, è possibile creare un materiale che reagisca "correttamente" in tutti gli scenari di illuminazione.

    + + In pratica questo fornisce un risultato dall'aspetto più accurato e realistico rispetto a [page:MeshLambertMaterial] + o [page:MeshPhongMaterial], a costo di essere un po' più costoso dal punto di vista computazionale. + [name] utilizza l'ombreggiatura per-fragment.

    + + Si noti che per ottenere risultati migliori si deve sempre specificare una [page:.envMap mappa ambientale] + quando si utilizza questo materiale.

    + + Per un'introduzione non tecnica al concetto di PBR e come impostare il materiale PBR, + consulta questi articoli delle persone di [link:https://www.marmoset.co marmoset]: + +

    + Un materiale renderizzato con shader personalizzati. Uno shader è un piccolo programma scritto in + [link:https://www.khronos.org/files/opengles_shading_language.pdf GLSL] + che viene eseguito sulla GPU. + Potresti voler utilizzare uno shader personalizzato se hai bisogno di: +

      +
    • implementare un effetto non incluso in nessuno dei [page:Material materiali] incorporati
      • +
    • combinare più oggetti in una singola [page:BufferGeometry] per migliorare le prestazioni
      • +
    + Di seguito ci sono delle informazioni da tenere a mente quando si utilizza uno `ShaderMaterial`: + +
      +
    • + Uno `ShaderMaterial` sarà renderizzato corretamente solo da [page:WebGLRenderer], + poiché il codice GLSL nelle proprietà [link:https://en.wikipedia.org/wiki/Shader#Vertex_shaders vertexShader] + e [link:https://en.wikipedia.org/wiki/Shader#Pixel_shaders fragmentShader] deve essere compilato ed eseguito + sulla GPU utilizzando WebGL. +
      • +
    • + A partire da THREE r72, l'assegnazione diretta di attributi in uno ShaderMaterial non è più supportata. + È invece necessario utilizzare un'istanza di [page:BufferGeometry], utilizzando le istanze [page:BufferAttribute] + per definire gli attributi personalizzati. +
      • +
    • + A partire da THREE r77, le istanze [page:WebGLRenderTarget] o [page:WebGLCubeRenderTarget] + non devono essere più utilizzate come uniformi. Al loro posto è necessario utilizzare la loro proprietà [page:Texture texture]. +
      • +
    • + Gli attributi e le uniformi integrati vengono passati agli shader insieme al codice. + Se non vuoi che [page:WebGLProgram] aggiunga nulla al tuo codice shader, puoi usare [page:RawShaderMaterial] invece di questa classe. +
      • +

        +
      • + Il loop deve essere [link:https://en.wikipedia.org/wiki/Normalized_loop normalizzato]. +
        • +
      • + La variabile del loop deve essere *i*. +

    Vertex shader e fragment shader

    + +
    +

    Si possono specificare due differenti tipi di shader per ogni materiale:

    +
      +
    • + Il vertex shader viene eseguito per primo; riceve gli `attributes` (attributi), calcola / manipola + la posizione di ogni singolo vertice, e passa valori aggiuntivi (`varying`) al fragment shader. +
      • +
    • + Il fragment (o pixel) shader viene eseguito per secondo; imposta il colore di ogni singolo "fragment" (pixel) + visualizzato nello schermo. +
      • +
    +

    Ci sono tre tipi di variabili negli shader: uniforms (uniformi), attributes (attributi), e varyings (variazioni):

    +
      +
    • + `Uniforms` sono variabili che hanno lo stesso valore per tutti i vertici - mappe di illuminazione, nebbia, + e mappe di ombreggiatura sono esempi di dati che verrebbero memorizzati nelle variabili uniformi. + È possibile accedere a queste varibili sia dal vertex shader sia dal fragment shader. +
      • +
    • + `Attributes` sono variabili associate ad ogni vertice; ad esempio, la posizione del vertice, + la normale della faccia e il colore del vertice sono tutti esempi di dati che dovrebbero essere + memorizzati negli attributi. Si può accedere a queste variabili `solo` dal vertex shader. +
      • +
    • + `Varyings` sono variabili che vengono passate da il vertex shader al fragment shader. + Per ogni fragment, il valore di ogni variazione sarà interpolato senza problemi dai valori dei vertici adiacenti. +
      • +
    +

    + Si noti che `all'interno` dello shader stesso, uniforms e attributes agiscono come costanti; + si può solo modificare i loro valori passando valori diversi ai buffer dal codice JavaScript. +

    +
    + + +

    Attributi e uniformi incorporati

    + +
    +

    + Il [page:WebGLRenderer] fornisce da impostazione predefinita molti attributi e uniformi agli shader; + le definizioni di queste variabili vengono anteposte al codice `fragmentShader` e `vertexShader` dal + [page:WebGLProgram] quando lo shader viene compilato; non è necessario che li dichiari tu stesso. + Vedi [page:WebGLProgram] per il dettaglio di queste variabili. +

    +

    + Alcune di queste uniformi o attributi (per esempio quelli relativi all'illuminazione, alla nebbia, etc.) + richiedono l'impostazione delle proprietà sul materiale affinché [page:WebGLRenderer] possa + copiare i valori appropriati alla GPU - assicurati di impostare questi flag se vuoi utilizzare + queste funzionalità nel tuo shader. +

    +

    + Se non vuoi che [page:WebGLProgram] aggiungera niente al tuo codice shader, puoi usare + [page:RawShaderMaterial] invece di questa classe. +

    +
    + + +

    Attributi e uniformi personalizzate

    + +
    +

    + Sia gli attributi personalizzati che le uniformi personalizzate devono essere dichiarate nel + tuo codice shader GLSL (all'interno di `vertexShader` e/o `fragmentShader`). + Le uniformi personalizzate devono essere definite in `entrambe` le proprietà `uniforms` del tuo `ShaderMaterial`, + mentre qualsiasi attributo personalizzato deve essere definito tramite le istanze di [page:BufferAttribute]. + Si noti che è necessario dichiarare le variazioni solo all'interno del codice shader (non all'iterno del materiale). +

    +

    + Per dichiarare un attributo personalizzato, fare riferimento alla pagina [page:BufferGeometry] per una panoramica, + e la pagina [page:BufferAttribute] per uno sguardo dettagliato alle API `BufferAttribute`. +

    +

    + Quando crei i tuoi attributi, ogni array tipizzato che crei per contenere i + dati del tuo attributo deve essere multiplo della dimensione del tuo tipo di dati. + Per esempio, se il tuo attributo è di tipo [page:Vector3 THREE.Vector3], e hai 3000 vertici + nel tuo [page:BufferGeometry], il valore del tuo array tipizzato deve essere creato con una + lunghezza di 3000 * 3, o 9000 (un valore per componente). + Di seguito viene mostrata una tabella delle dimensioni di ciascun tipo di dati come riferimento: +

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    Dimensioni attributi
    Tipo GLSLTipo JavaScriptDimensione
    float[page:Number]1
    vec2[page:Vector2 THREE.Vector2]2
    vec3[page:Vector3 THREE.Vector3]3
    vec3[page:Color THREE.Color]3
    vec4[page:Vector4 THREE.Vector4]4
    + +

    + Si noti che i buffer degli attributi `non` vengono aggiornati automaticamente quando i loro valori cambiano. + Per aggiornare gli attributi personalizzati, imposta il flag `needsUpdate` a true sul [page:BufferAttribute] + della geometria (vedi [page:BufferGeometry] per maggiori dettagli). +

    + +

    + Per dichiarare una [page:Uniform] personalizzata, utilizzare la proprietà `uniforms`: + +uniforms: { + time: { value: 1.0 }, + resolution: { value: new THREE.Vector2() } +} + +

    + +

    + Si consiglia di aggiornare i valori di [page:Uniform] personalizzati in base all'[page:Object3D object] e alla [page:Camera telecamera] + in [page:Object3D.onBeforeRender] poiché il [page:Material Materiale] può essere condiviso tra le [page:Mesh mesh], + la [page:Matrix4 matrixWorld] della [page:Scene scena] e la [page:Camera telecamera] viene aggiornata in [page:WebGLRenderer.render], + e alcuni effetti eseguono il rendering di una scena con le proprie [page:Camera telecamere] private. +

    [name]

    + +

    + Una classe che rappresenta gli [link:http://en.wikipedia.org/wiki/Euler_angles angoli di Eulero].

    + + Gli angoli di eulero descrivono una trasformazione rotazionale ruotando un oggetto sui suoi vari assi + in quantità specifiche per asse, e in un ordine specificato per asse. +

    + +

    + L'iterazione di un'istanza di [name] produce le sue componenti (x, y, z, order) nell'ordine corrispondente. +

    + +

    Codice di Esempio

    + + const a = new THREE.Euler( 0, 1, 1.57, 'XYZ' ); + const b = new THREE.Vector3( 1, 0, 1 ); + b.applyEuler(a); + + + +

    Costruttore

    + + +

    [name]( [param:Float x], [param:Float y], [param:Float z], [param:String order] )

    + + +

    Proprietà

    + +

    [property:Boolean isEuler]

    +

    + Flag di sola lettura per verificare se l'oggetto dato è di tipo [name]. +

    + +

    [property:String order]

    + + Three.js utilizza gli angoli Tait-Bryan `intrinseci`. Questo significa che le rotazioni vengono eseguite + rispettando il sistema di coordinate `locale`. Cioè per l'ordine 'XYZ', la rotazione verrà prima eseguita + intorno all'asse locale X (il che è lo stesso dell'asse world X), poi intorno all'asse locale Y (che può essere diversa dall'asse + world Y), ed infine intorno all'asse Z (che può essere diversa dall'asse world Z). +

    [name]

    + +

    + Classe base astratta di interpolanti su campioni parametrici.

    + + Il dominio del parametro è unidimensionale, tipicamente il tempo o un path lungo una curva definita dai dati.

    + + I valori campione possono avere qualsiasi dimensionalità e le classi derivate possono applicare interpolazioni ai dati.

    + + Questa classe fornisce l'intervallo di ricerca in un Metodo Modello, rinviando l'interpolazione effettiva alle classi derivate.

    + + La complessità del tempo è `O(1)` per l'accesso lineare che attraversa al massimo due punti e `O(log N)` per l'accesso casuale, + dove *N* è il numero di posizioni.

    [name]

    + +

    + Una classe che rappresenta una [link:https://en.wikipedia.org/wiki/Matrix_(mathematics) matrice] 4x4.

    + + L'uso più comune di una matrice 4x4 nella grafica 3D è come una + [link:https://en.wikipedia.org/wiki/Transformation_matrix matrice di trasformazione]. + + Per un'introduzione alle matrici di trasformazione utilizzate in WebGL, + dai un'occhiata a [link:http://www.opengl-tutorial.org/beginners-tutorials/tutorial-3-matrices questo tutorial].

    + + Ciò consente ad un [page:Vector3] che rappresenta un punto nello spazio 3D di subire trasformazioni come traslazione, rotazione + taglio, scala, riflessione, proiezione ortogonale o prospettica e così via, moltiplicandosi per la matrice. + Questo è noto come `applicare` la matrice al vettore.

    + + Ogni [page:Object3D] ha tre Matrix4 associate: +

      +
    • + [page:Object3D.matrix]: Questo memorizza la trasfomazione locale dell'oggetto. Questa è la trasformazione dell'oggetto rispetto al suo genitore. +
      • +
    • + [page:Object3D.matrixWorld]: La trasformazione globale o world dell'oggetto. Se l'oggetto non ha un genitore, allora questo è identico + alla trasformazione locale memorizzata nella [page:Object3D.matrix matrix]. +
      • +
    • + [page:Object3D.modelViewMatrix]: Questo rappresenta la trasformazione dell'oggetto rispetto al sistema di coordinate della telecamera. + Il modelViewMatrix dell'oggetto è il matrixWorld dell'oggetto pre-moltiplicato per il matrixWorldInverse della telecamera. +
      • +
    + + Le [page:Camera Telecamere] hanno tre Matrix4 addizionali: +
      +
    • + [page:Camera.matrixWorldInverse]: La matrice di visualizzazione - l'inversa della [page:Object3D.matrixWorld matrixWorld] della telecamera. +
      • +
    • + [page:Camera.projectionMatrix]: Rappresenta le informazioni su come proiettare la scena nello spazio di ritaglio. +
      • +
    • + [page:Camera.projectionMatrixInverse]: L'inverso della projectionMatrix. +
      • +
    + Nota: [page:Object3D.normalMatrix] non è una Matrix4, ma una [page:Matrix3]. +

    + +

    Una nota sull'ordine delle Row-Major (righe principali) e delle Column-Major (colonne principali)

    +

    + Il metodo [page:set]() accetta gli argomenti in ordine + [link:https://en.wikipedia.org/wiki/Row-_and_column-major_order#Column-major_order row-major], mentre internamente + vengono memorizzati nell'array [page:.elements elements] nell'ordine column-major.

    + + Ciò significa che la chiamata a + +const m = new THREE.Matrix4(); + +m.set( 11, 12, 13, 14, + 21, 22, 23, 24, + 31, 32, 33, 34, + 41, 42, 43, 44 ); + + + risulterà nell'array [page:.elements elements] contenente: + +m.elements = [ 11, 21, 31, 41, + 12, 22, 32, 42, + 13, 23, 33, 43, + 14, 24, 34, 44 ]; + + e internamente tutti i calcoli vengono eseguiti utilizzando l'ordine column-major. Tuttavia, poiché l'ordine + effettivo non fa alcune differenza matematicamente e la maggior parte delle persone è abituata a pensare alle + matrici nell'ordine row-major, la documentazione di three.js mostra le matrici in ordine di row-major. + Tieni solo a mente che se stai leggendo il codice sorgente, dovrai prendere la [link:https://en.wikipedia.org/wiki/Transpose trasposizione] + di tutte le matrici qui descritte per dare un senso ai calcoli. +

    + +

    Estrazione della posizione, della rotazione e del ridimensionamento

    +

    + Ci sono molte opzioni disponibili per l'estrazione della posizione, della rotazione e del ridimensionamento da una Matrix4. +

      +
    • + [page:Vector3.setFromMatrixPosition]: può essere utilizzato per estrarre il componente traslazione. +
      • +
    • + [page:Vector3.setFromMatrixScale]: può essere utilizzato per estrarre il componente ridimensionamento. +
      • +
    • + [page:Quaternion.setFromRotationMatrix], [page:Euler.setFromRotationMatrix] o [page:.extractRotation extractRotation] + può essere utilizzato per estrarre il componente rotazione da una matrice pura (non ridimensionata). +
      • +
    • + [page:.decompose decompose] può essere utilizzato per estrarre la posizione, la rotazione e il ridemsionamento tutti in uno. +

    +

    + L'argomento data deve essere un [link:https://developer.mozilla.org/en-US/docs/Web/API/ArrayBufferView ArrayBufferView]. + Ulteriori parametri corrispondono alle proprietà ereditate da [page:Texture], dove sia magFilter che minFilter per impostazione predefinita sono THREE.NearestFilter. +

    +

    + L'interpretazione dei dati dipende dal tipo e dal formato: + Se il tipo è THREE.UnsignedByteType, un Uint8Array sarà utile per indirizzare i dati texel. + Se il formato è THREE.RGBAFormat, i dati necessitano di quattro valori per un texel; Rosso, Verde, Blu e Alfa (tipicamente l'opacità).
    + + Per i tipi compressi, THREE.UnsignedShort4444Type e THREE.UnsignedShort5551Type tutti i componenti di colore di un texel possono essere + indirizzati come campi di bit all'interno di un elemento intero di un Uint16Array.
    + + Per utilizzare i tipi THREE.FloatType e THREE.HalfFloatType, l'implementazione WebGL deve supportare le + rispettive estensioni OES_texture_float e OES_texture_half_float. + Per utilizzare THREE.LinearFilter per l'interpolazione bilineare component-wise dei texel basati + su questi tipi, devono essere presenti anche le estensioni WebGL OES_texture_float_linear o OES_texture_half_float_linear. +

    + La definizione dei dati di una texture. Un riferimento alla sorgente dati può essere condiviso tra le texture. + Questo è spesso utile nel contesto di spritesheets in cui più texture rendono gli stessi dati ma con diverse trasformazioni di texture. +

    + +

    Metodi

    + +

    I metodi [page:EventDispatcher EventDispatcher] sono disponibili su questa classe.

    + +

    [method:undefined updateMatrix]()

    +

    + Aggiorna la [page:Texture.matrix .matrix] uv-transform della texture dalle proprietà della texture + [page:Texture.offset .offset], [page:Texture.repeat .repeat], [page:Texture.rotation .rotation], e [page:Texture.center .center]. +

    + +

    [method:Texture clone]()

    +

    + Crea una copia della texture. Si noti che non è una "copia profonda", l'immagine è condivisa. + Inoltre, la clonazione della texture non la contrassegna automaticamente per il caricamento di una texture. + Devi impostare [page:Texture.needsUpdate .needsUpdate] a true non appena la sua proprietà dell'immagine + (l'origine dati) è completamente caricata o pronta. +

    + +

    [method:Object toJSON]( [param:Object meta] )

    +

    + meta -- oggetto opzionale contenente i metadati.
    + Converte l'origine dati nel [link:https://github.com/mrdoob/three.js/wiki/JSON-Object-Scene-format-4 formato JSON Oggetto/Scena] di three.js. +

    + +

    [method:undefined dispose]()

    +

    + Libera le risorse relative alla GPU allocate da questa istanza. + Chiama questo metodo ogni volta che questa istanza non viene più utilizzata dall'applicazione. +

    + +

    [method:Vector2 transformUv]( [param:Vector2 uv] )

    +

    + Trasforma l'uv in base al valore delle proprietà [page:Texture.offset .offset], [page:Texture.repeat .repeat], + [page:Texture.wrapS .wrapS], [page:Texture.wrapT .wrapT] e [page:Texture.flipY .flipY]. +

    + + +

    Propriedades

    + +

    [property:Boolean clampWhenFinished]

    +

    + Se `clampWhenFinished` estiver definido como true a animação será automaticamente [page:.paused pausada] + em seu último quadro.

    + + Se `clampWhenFinished` estiver definido como false, [page:.enabled enabled] será trocado automaticamente + para false quando o último loop da ação terminar, para que esta ação não tenha mais impacto.

    + + O padrão é falso.

    + + Nota: `clampWhenFinished` não tem impacto se a ação for interrompida (só tem efeito se + seu último loop realmente terminou). +

    + +

    [property:Boolean enabled]

    +

    + Definir `enabled` como `false` desativa esta ação, para que não tenha efeito. O padrão é `true`.

    + + Quando a ação é reativada, a animação continua de seu [page:.time time] (tempo) + (configurar `enabled` para `false` não redefine a ação).

    + + Nota: Definir `enabled` como `true` não reinicia automaticamente a animação. Configurar `enabled` + para `true` só reiniciará a animação imediatamente se a seguinte condição for atendida: + [page:.paused paused] é `false`, esta ação não foi desativada nesse meio tempo + (executando um comando [page:.stop stop] ou [page:.reset reset]), e nem [page:.weight weight] + nem [page:.timeScale timeScale] são `0`. +

    + +

    [property:Number loop]

    +

    + O modo de looping (pode ser alterado com [page:.setLoop setLoop]). O padrão é + [page:Animation THREE.LoopRepeat] (com um número infinito de [page:.repetitions repetitions] (repetições)).

    + + Deve ser uma destas constantes:

    + [page:Animation THREE.LoopOnce] - reproduzindo o clipe uma vez,
    + [page:Animation THREE.LoopRepeat] - reproduzindo o clipe com o número escolhido de `repetições`, + cada vez pulando do final do clipe diretamente para o início,
    + [page:Animation THREE.LoopPingPong] - reproduzindo o clipe com o número escolhido de `repetições`, + tocando alternadamente para frente e para trás. +

    + +

    [property:Boolean paused]

    +

    + Definir `paused` como `true` pausa a execução da ação definindo a escala de tempo efetiva + para '0'. O padrão é `false`.

    +

    + +

    [property:Number repetitions]

    +

    + O número de repetições do [page:AnimationClip] ao longo desta ação. + Pode ser definido através de [page:.setLoop setLoop]. O padrão é `Infinity`.

    + Definir este número não tem efeito se o [page:.loop modo de loop] está configurado como + [page:Animation THREE.LoopOnce]. +

    + +

    [property:Number time]

    +

    + O tempo local desta ação (em segundos, começando com `0`).

    + + O valor é fixado ou encapsulado em `0...clip.duration` (de acordo com o estado do loop). Pode ser + dimensionado em relação ao tempo do mixer global, alterando [page:.timeScale timeScale] (usando + [page:.setEffectiveTimeScale setEffectiveTimeScale] ou [page:.setDuration setDuration]).
    +

    + +

    [property:Number timeScale]

    + Em contraste com a hierarquia de animação do + [link:https://github.com/mrdoob/three.js/wiki/JSON-Model-format-3 JSON model format] uma + `KeyframeTrack` não armazena seus keyframes únicos como objetos em um array de "chaves" (mantendo os + tempos e os valores de cada frame juntos em um só lugar). +

    + +

    + Em vez disso, há sempre dois arrays em um `KeyframeTrack`: o array [page:.times times] + armazena os valores de tempo para todos os keyframes desta track em ordem sequencial, e o + array [page:.values values] contém os valores alterados correspondentes da propriedade animada. +

    + +

    + Um único valor, pertencente a um determinado ponto do tempo, pode não ser apenas um simples número, mas (por + exemplo) um vetor (se uma posição for animada) ou um quaternion (se uma rotação for animada). Por + isso o array de valores (que também é um array plano) pode ser três ou quatro vezes maior que + o array de tempo. +

    + +

    + Correspondendo aos diferentes tipos possíveis de valores animados existem várias subclasses de + `KeyframeTrack`, herdando a maioria das propriedades e métodos: +

    + +
      +
    • [page:BooleanKeyframeTrack]
      • +
    • [page:ColorKeyframeTrack]
      • +
    • [page:NumberKeyframeTrack]
      • +
    • [page:QuaternionKeyframeTrack]
      • +
    • [page:StringKeyframeTrack]
      • +
    • [page:VectorKeyframeTrack]
      • +
    + +

    + Alguns exemplos de como criar manualmente [page:AnimationClip AnimationClips] com diferentes tipos de + KeyframeTracks pode ser encontrado no arquivo [link:https://threejs.org/examples/jsm/animation/AnimationClipCreator.js AnimationClipCreator]. +

    + +

    + Como os valores explícitos são especificados apenas para os pontos discretos de tempo armazenados no array de tempo, + todos os valores intermediários devem ser interpolados. +

    + +

    + O nome da track é importante para a conexão desta track com uma propriedade específica do + nó animado (feito por [page:PropertyBinding]). +

    + + +

    Construtor

    + + +

    [name]( [param:String name], [param:Array times], [param:Array values], [param:Constant interpolation] )

    +

    + [page:String name] - o identificador do `KeyframeTrack`.
    + [page:Array times] - um array de keyframes, convertidos internamente para um + [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Float32Array Float32Array].
    + [page:Array values] - um array com os valores relacionados ao array times, convertidos internamente para um + [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Float32Array Float32Array].
    + [page:Constant interpolation] - o tipo de interpolação a ser usado. Ver + [page:Animation Animation Constants] para valores possíveis. O padrão é [page:Animation InterpolateLinear]. +

    + + +

    Propriedades

    + + +

    [property:String name]

    +

    + O nome da track pode se referir a morph targets ou [page:SkinnedMesh bones] ou possivelmente outros valores dentro de um objeto animado. Ver + [page:PropertyBinding.parseTrackName] para as formas de strings que podem ser analisadas para propriedades + vinculativas: +

    + +

    + O nome pode especificar o nó usando seu nome ou seu uuid (embora precise estar na + subárvore do nó do grafo de cena passado para o mixer). Ou, se o nome da track começar com um ponto, + a track se aplica ao nó raiz que foi passado para o mixer. +

    + +

    + Normalmente, após o nó, uma propriedade será especificada diretamente. Mas você também pode especificar um + subpropriedade, como .rotation[x], se você quiser apenas direcionar o componente X da rotação + através de uma track flutuante. +

    + +

    + Você também pode especificar bones ou multimateriais usando um nome de objeto, por exemplo: + .bones[R_hand].scale; o canal vermelho da cor difusa do quarto material em um + array de materiais - como um exemplo - pode ser acessado com .materials[3].diffuse[r]. +

    + +

    + PropertyBinding também resolverá nomes de morph targets, por exemplo: .morphTargetInfluences[run]. +

    + +

    + Nota: o nome da track não precisa necessariamente ser único. Várias tracks podem conduzir a mesma + propriedade. O resultado deve ser baseado em uma mistura ponderada entre as várias tracks de acordo com + os pesos de suas respectivas ações. +

    + +

    [property:Float32Array times]

    +

    + Um [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Float32Array Float32Array], + convertido do array de tempos que é passado no construtor. +

    خرائط الإستيراد

    Node.js

    - قد يكون استخدام three.js في Node.js أمرًا صعبًا ، وذلك لسببين: -

    - -

    - أولاً ، نظرًا لأن three.js مصممة للويب ، فإنها تعتمد على المتصفح وواجهات برمجة تطبيقات DOM التي لا تتواجد دائمًا في Node.js. يمكن حل بعض هذه المشكلات باستخدام (shims) مثل [link:https://github.com/stackgl/headless-gl headless-gl]، أو عن طريق استبدال مكونات مثل [page:TextureLoader] ببدائل مخصصة. قد تتشابك واجهات برمجة تطبيقات DOM الأخرى بعمق مع الكود الذي يستخدمها ، وسيكون من الصعب حلها. نرحب بطلبات السحب البسيطة والقابلة للصيانة لتحسين دعم Node.js ، لكننا نوصي بفتح مشكلة لمناقشة التحسينات التي أجريتها أولاً. + Because three.js is built for the web, it depends on browser and DOM APIs that don't always exist in Node.js. Some of these issues can be resolved by using shims like [link:https://github.com/stackgl/headless-gl headless-gl], or by replacing components like [page:TextureLoader] with custom alternatives. Other DOM APIs may be deeply intertwined with the code that uses them, and will be harder to work around. We welcome simple and maintainable pull requests to improve Node.js support, but recommend opening an issue to discuss your improvements first.

    - ثانيًا ، دعم Node.js لوحدات ES ... معقد. بدءًا من الإصدار 12 من Node.js ، يمكن استيراد المكتبة الأساسية كوحدة نمطية CommonJS ، مع require('three'). ومع ذلك ، فإن معظم أمثلة المكونات في examples/jsm لا يمكنها ذلك. - قد تحل الإصدارات المستقبلية من Node.js هذه المشكلة ، ولكن في هذه الأثناء قد تحتاج إلى استخدام حلول بديلة مثل [link:https://github.com/standard-things/esm esm] لتمكين تطبيق Node.js الخاص بك من التعرف على وحدات ES. + Make sure to add `{ "type": "module" }` to your `package.json` to enable ES6 modules in your node project.

    CommonJS imports

    Node.js

    - Using three.js in [link:https://eloquentjavascript.net/20_node.html Node.js] can be difficult, for two reasons: -

    - -

    - First, because three.js is built for the web, it depends on browser and DOM APIs that don't always exist in Node.js. Some of these issues can be resolved by using shims like [link:https://github.com/stackgl/headless-gl headless-gl], or by replacing components like [page:TextureLoader] with custom alternatives. Other DOM APIs may be deeply intertwined with the code that uses them, and will be harder to work around.

    - Second, Node.js support for ES modules is ... complicated. As of Node.js v12, the core library can be imported as a CommonJS module, with require('three'). However, most example components in examples/jsm cannot. Future versions of Node.js may resolve this, but in the meantime you may need to use workarounds like [link:https://github.com/standard-things/esm esm] to enable your Node.js application to recognize ES modules. + Make sure to add `{ "type": "module" }` to your `package.json` to enable ES6 modules in your node project.

      Tests avec NPM ([name])

      + +

      + Ici vous sera expliqué comment obtenir three.js dans un environnement [link:https://nodejs.org/en/ node.js] pour que + vous puissez exécuter des tests automatisés. Les tests peuvent êtres lancés en lignes de commande, ou grâce à des + outils de CI automatisés comme [link:https://travis-ci.org/ Travis]. +

      + +

      La version courte

      + +

      + Si vous êtes à l'aise avec node et npm, + + $ npm install three --save-dev + + et ajoutez + + const THREE = require('three'); + + à votre test. +

      + +

      Créer un projet testable de zéro

      +

      + Si vous n'êtes pas familier avec ces outils, vous trouverez ici un guide rapide (pour linux, le processus d'installation + sera légèrement différent de celui pour Windows, mais les commandes NPM sont identiques). +

      + +

      Setup basique

      +
      +
        +
      1. + Installez [link:https://www.npmjs.org/ npm] et nodejs. La méthode la plus rapide ressemble généralement à + +$ sudo apt-get install -y npm nodejs-legacy +# fix any problems with SSL in the default registry URL +$ npm config set registry http://registry.npmjs.org/ + +
        2. + +
      2. + Créez un nouveau répertoire de projet + + $ mkdir test-example; cd test-example + +
        3. + +
      3. + Demandez à npm de créer un nouveau fichier de projet pour vous: + + $ npm init + + et acceptez tous les paramètres par défaut en appuyant sur Entrée à chaque prompt. + Cela créera package.json. +

        4. + +
      4. + Essayez la fonctionnalité de test avec + +$ npm test + + Cela va échouer, comme prévu. + Si vous jetez un coup d'oeil à votre package.json, la définition du test de script sera + + "test": "echo \"Error: no test specified\" && exit 1" + +
        5. + +
      +
      + +

      Ajouter mocha

      +
      + Nous allons utiliser [link:https://mochajs.org/ mocha]. + +
        +
      1. + Installez mocha avec + +$ npm install mocha --save-dev + + Remarquez que node_modules/ est créé et que vos dépendances y apparaissent. + Notez également que votre package.json a été mis à jour: la propriété devDependencies + est ajoutée et mis à jour par l'utilisation de --save-dev. +

        2. + +
      2. + Modifiez votre package.json pour qu'il utilise mocha pour effectuer les tests. Lorsqu'un test est invoqué, nous voulons simplement lancer + mocha et spécifier un verbose reporter. Par défaut cela lancera le contenu de test/ + (ne pas avoir de répertoire test/ peut causer une npm ERR!, créez le en utilisant mkdir test) + + "test": "mocha --reporter list" + +
        3. + +
      3. + Relancez les tests avec + + $ npm test + + + Cela doit maintenant réussir, signalant 0 passages (1ms) + ou similaire. +
        4. + +
      +
      + +

      Ajouter three.js

      +
      +
        +
      1. + Ajoutons notre dépendance de three.js avec + +$ npm install three --save-dev + +
          +
        • + Si vous avez besoin d'une version de three différente, utilisez + + $ npm show three versions + + pour voir + ce qui est disponible. Pour indiquer à npm la bonne, utilisez + + $ npm install three@0.84.0 --save + + (0.84.0 dans cet exemple). --save qui en fait une dépendance de ce projet, au lieu + d'une dépendance dev. Voir la documentation [link:https://docs.npmjs.com/cli/v8/configuring-npm/package-json ici] pour plus d'informations. +
          • +
        +
        2. + +
      2. + Mocha cherche des tests dans test/, exécutons donc la commande + + $ mkdir test + +
        3. + +
      3. + Finalement, nous avons besoin d'un test JS à lancer. Ajoutons un test simple qui va vérifier que + l'objet three.js est disponible et fonctionnel. Créez test/verify-three.js contenant: + +const THREE = require('three'); +const assert = require('assert'); + +describe('The THREE object', function() { + it('should have a defined BasicShadowMap constant', function() { + assert.notEqual('undefined', THREE.BasicShadowMap); + }), + + it('should be able to construct a Vector3 with default of x=0', function() { + const vec3 = new THREE.Vector3(); + assert.equal(0, vec3.x); + }) +}) + +
        4. + +
      4. + Finalement testons à nouveau avec $ npm test. Cela doit lancer le test ci-dessous et réussir, + affichant quelque chose du genre: + +The THREE object should have a defined BasicShadowMap constant: 0ms +The THREE object should be able to construct a Vector3 with default of x=0: 0ms +2 passing (8ms) + +
        5. +
      +
      + +

      Ajoutez votre propre code

      +
      + Vous devez faire trois choses: + +
        +
      1. + Écrivez un test pour un comportement attendu de votre code, et placez-le sous test/. + [link:https://github.com/air/encounter/blob/master/test/Physics-test.js Ici] vous trouverez un exemple issu d'un vrai projet. +
        2. + +
      2. + Exportez votre code de manière à ce que nodejs puisse le voir et l'utiliser quand la conjoncture le requiert. + Voir [link:https://github.com/air/encounter/blob/master/js/Physics.js ici]. +
        3. + +
      3. + Puis il faut require votre code dans le fichier de test, de la même manière que nous avons require('three') dans l'exemple au-dessus. +
        4. +
      + +

      + Les items 2 et 3 varient selon la façon dont vous organisez votre code. Dans l'exemple de Physics.js + montré plus-haut, la partie concernant l'export est à la toute fin. Nous assignons un objet à module.exports: +

      + +//============================================================================= +// make available in nodejs +//============================================================================= +if (typeof exports !== 'undefined') +{ + module.exports = Physics; +} + +
      + +

      Gérer les dépendances

      +
      +

      + Si vous utlisez déjà quelque chose d'astucieux comme require.js ou browserify, sautez cette partie. +

      +

      + Généralement un projet three.js s'exécute dans le navigateur. Le module de chargement est par conséquent réalisé par + le navigateur qui exécute un ensemble de scripts. Vos fichiers individuels n'ont pas à gérer les + dépendances. Dans un contexte nodejs, il n'y a pas d'index.html reliant tout + ensemble, vous devez donc être explicites. +

      +

      + Si vous exportez un module qui dépend d'autres fichiers, vous devrez dire à node de les charger. + Voici une approche: +

      +
        +
      1. + Au début de votre module, vérifiez si vous êtes dans un environnement nodejs. +
        2. +
      2. + Si c'est le cas, déclarez explicitement vos dépendances. +
        3. +
      3. + Si ce n'est pas le cas, vous êtes probablement dans un navigateur vous n'avez donc rien d'autre à faire. +
        4. +
      + Code d'exemple issu de Physics.js: + +//============================================================================= +// setup for server-side testing +//============================================================================= +if (typeof require === 'function') // test for nodejs environment +{ + const THREE = require('three'); + const MY3 = require('./MY3.js'); +} + +

      Système d'animation ([name])

      + +

      Aperçu

      + +

      + Dans le système d'animation de three.js vous pouvez animer différentes propriétés de vos modèles: + les os d'un [page:SkinnedMesh skinned and rigged model], les morph targets, les différentes propriétés des matériaux + (couleurs, opacité, booléens), la visibilité et les transformations. Les propriétés animées peuvent avoir différentes animations comme un fade-in, + un fade-out, un fondu ou un warp. Le poids et l'échelle temporelle des différentes animations simultanées + sur le même objet peuvent également être changées indépendamment. + Différentes animations sur le même objet peuvent-être + synchronisées.

      + + Pour effectuer tout cela dans un système homogène, le système d'animation three.js + [link:https://github.com/mrdoob/three.js/issues/6881 a complètement changé en 2015] + (attention aux informations dépassées!), et a maintenant une architecture similaire à + Unity/Unreal Engine 4. Cette page offre un bref aperçu des principaux composants du système + et de comment ils fonctionnent ensemble. + +

      + +

      Animation Clips

      + +

      + + Si vous aveez réussi à importer un modèle 3D (peu importe qu'il ait + des os ou une morph targets ou les deux) — par exemple en l'exportant depuis Blender avec le + [link:https://github.com/KhronosGroup/glTF-Blender-IO glTF Blender exporter] et + en le chargeant dans la scène three.js en utilisant [page:GLTFLoader] — un des champs doit-être + un tableau nommé "animations", contenant les [page:AnimationClip AnimationClips] + pour ce modèle (voir une liste des loaders possibles ci-dessous).

      + + Chaque `AnimationClip` conserve les données d'une certaine activité d'un objet. Si le + mesh est un personnage, par exemple, il pourrait y avoir un AnimationClip pour une marche, un second + pour un saut, un troisième pour un pas de côté et ainsi de suite. + +

      + +

      Keyframe Tracks

      + +

      + + A l'intérieur d'un `AnimationClip` les données pour chaque propriétés animées sont stockées + dans un [page:KeyframeTrack] séparé. En considérant que l'objet personnage a un [page:Skeleton skeleton], + un keyframe track pourrait stocker les changements de valeur de la position de l'os inférieur d'un bras + à travers le temps, un track différent stockerait les changements de valeur de la rotation du même bras, un troisème + pourrait stocker la position, la rotation ou l'échelle d'un autre os, ainsi de suite. Il doit-être clair qu'un, + AnimationClip peut-être composé de beaucoup de ce genre de tracks.

      + + En considérant que le modèle a un morph targets (par exemple un morph + target pour un visage amical et un autre pour un visage énervé), chaque track conserve + l'information de comment l'[page:Mesh.morphTargetInfluences influence] d'un certain morph + change durant l'exécution du clip. + +

      + +

      Mixer d'Animations

      + +

      + + Les informations stockées représentent uniquement la base de l'animation - le playback est en réalité contrôlé par + l'[page:AnimationMixer]. Vous vous doutez bien que ce n'est pas uniquement un visualiseur d'animations, mais + une simulation d'un hardware comme une vraie console de mixage , qui peut contrôler plusieurs animations + simultanément, les mélangeant et les fusionnant. + +

      + +

      Actions d'Animations

      + +

      + + L'`AnimationMixer` en lui-même a seulement quelques propriétés (générales) et méthodes, car il + peut-être contrôlé par l'[page:AnimationAction AnimationActions]. En configurant un + `AnimationAction` vous pouvez déterminer qu'un certain `AnimationClip` doit-être joué, mis en pause + ou stoppé sur un des mixers, si et à quelle fréquence le clip doit-être répeté, si il + doit-être joué avec un fade, une mise à l'échelle temporelle, et d'autres choses, comme le fondu + ou la synchronisation. + +

      + +

      Animations de Groupes d'Objets

      + +

      + + Si vous voulez qu'un groupe d'objets reçoive un statut d'animation partagé, vous pouvez utiliser un + [page:AnimationObjectGroup]. + +

      + +

      Formats et loaders supportés

      + +

      + Notez que tous les formats de modèles n'incluent pas les animations (notamment OBJ ne les supporte pas), et que seulement certains + loaders three.js supportent les séquences d'[page:AnimationClip AnimationClip]. Plusieurs autres supportent + ce type d'animations: +

      + +
        +
      • [page:ObjectLoader THREE.ObjectLoader]
        • +
      • THREE.BVHLoader

      • [page:GLTFLoader THREE.GLTFLoader]
        • +
      • THREE.MMDLoader
        • +
      + +

      + Notez que 3ds max et Maya ne peuvent actuellement pas exporter plusieurs animations (qui ne sont pas sur + la même timeline) directement dans un seul fichier. +

      + +

      Exemple

      + + + let mesh; + + // Create an AnimationMixer, and get the list of AnimationClip instances + const mixer = new THREE.AnimationMixer( mesh ); + const clips = mesh.animations; + + // Update the mixer on each frame + function update () { + mixer.update( deltaSeconds ); + } + + // Play a specific animation + const clip = THREE.AnimationClip.findByName( clips, 'dance' ); + const action = mixer.clipAction( clip ); + action.play(); + + // Play all animations + clips.forEach( function ( clip ) { + mixer.clipAction( clip ).play(); + } ); + + + + diff --git a/docs/manual/fr/introduction/Color-management.html b/docs/manual/fr/introduction/Color-management.html new file mode 100644 index 00000000000000..e6c63391e6d42f --- /dev/null +++ b/docs/manual/fr/introduction/Color-management.html @@ -0,0 +1,328 @@ + + + + + + + + + + + + +

      Gestion des couleurs ([name])

      + +

      Qu'est ce qu'un espace colorimétrique?

      + +

      + Chaque espace colorimétrique est un ensemble de plusieurs décisions de design, choisies ensemble pour supporter + un large éventail de couleurs tout en satisfaisant les contraites techniques liées à la précision et aux technologies + d'affichage. Lors de la création d'un asset 3D, ou l'assemblage d'assets 3D ensemble dans une scène, il est + important de savoir quelles sont ces propriétés, et comment les propriétés d'un espace colorimétrique se rapporte + aux autres espaces colorimétriques de la scène. +

      + +
      + +
      + Les couleurs sRGB et le point blanc (D65) affichées dans le modèle CIE 1931 chromaticity + diagram. Les régions colorées représentent une projection 2D de la gamme sRGB, qui est un + volume 3D. Source: Wikipedia +
      +
      + +
        +
      • + Couleurs primaires: Les couleurs primaires (e.g. rouge, vert, bleu) ne sont pas absolues; elle sont + sélectionnées depuis le spectre visible basé sur les contraintes de la précision limitée et + les capacités des appareils d'affichage disponibles. Les couleurs sont exprimées comme un ratio des couleurs primaires. +
        • +
      • + Point blanc: La plupart des espaces colorimétriques sont conçus de telle manière qu'une somme équivalente + de couleurs primaires R = G = B apparaissent comme n'ayant pas de couleurs, ou "achromatique". L'apparition + des valeurs chromatiques (comme le blanc ou le gris) dépend de la perception humaine, qui dépend elle-même + fortement du contexte d'observation. Un espace colorimétrique spécifie son "point blanc" pour équilibrer + ces besoins. Le point blanc définit par l'espace colorimétrique sRGB est + [link:https://en.wikipedia.org/wiki/Illuminant_D65 D65]. +
        • +
      • + Fonctions de transfert: Après avoir choisir la gamme de couleur et le modèle de couleur, il nous reste à toujours définir + le mapping ("fonctions de transfert") des valeurs numériques de l'espace colorimétrique. Est-ce-que r = 0.5 + représente 50% moins d'illumination physique que r = 1.0? Ou 50% de luminosité en moins, comme perçu + par l'oeil humain moyen? Ce sont différentes choses, et ces différences peuvent être représentées par + une fonction mathématique. Les fonctions de transfert peuvent être linéaires ou non-linéaires, selon + les objectifs de l'espace colorimétrique. Le sRGB définit des fonctions de transfert non-linéaires. Ces fonctions + fonctions sont parfois approximées en fonctions gamma, mais le terme "gamma" est + ambigu et doit-être évité dans ce contexte. +
        • +
      + + Ces trois paramètres — les couleurs primaires, le point blanc, et les fonctions de transfert — définissent un + espace colorimétrique, chacun est choisi pour un objectif particulier. Après avoir défini les paramètres, quelques termes supplémentaires + sont utiles: + +
        +
      • + Le modèle de couleur: La syntaxe pour identifier naturellement les couleurs au sein de la gamme de couleur choisie — + un système de coordonnées pour les couleurs. Dans three.js nous utilisons princpalement le système de couleurs RGB, + ayant trois coordonnées r, g, b ∈ [0,1] ("domaines fermés") ou + r, g, b ∈ [0,∞] ("domaine ouvert") chacune représentant une fraction d'une couleur + primaire. D'autres modèles de couleurs (HSL, Lab, LCH) sont communément utilisés pour un contrôle artistique. +
        • +
      • + La gamme de couleurs: Une fois que les couleurs primaires et le point blanc ont été choisis, ils représentent + un volume parmis le spectre visible (une "gamme"). Les couleurs qui ne sont pas dans ce volume ("hors de la gamme") + ne peuvent pas être exprimées par un domaine fermé [0,1] de valeurs RGB. Dans le domaine ouvert [0,∞], la gamme est + théoriquement infinie. +
        • +
      + +

      + Considérons deux espaces colorimétriques très communs: [page:SRGBColorSpace] ("sRGB") et + [page:LinearSRGBColorSpace] ("sRGB-Linéaire"). Les deux utilisent les mêmes primaires et point blanc, + et donc ont la même gamme de couleur. Le deux utilisent le modèle RGB. Leur seule différence sont + les fonctions de transfert — Le sRGB-Linéaire est linéaire et respecte l'intensité physique de la lumière. + Le sRGB utilise les fonctions de transfert non-linéaire du sRGB, et reproduit de manière plus proche la façon dont + l'oeil humain perçoit la lumière et la réactivité des écrans. +

      + +

      + Cette différence est imporante. Les calculs de lumières et les autres opérations de rendu doivent + généralement se produire dans un espace de lumière linéaire. Cependant, les espaces colorimétriques linéaires sont moins efficaces + dans le stockage d'images ou de framebuffer, et semblent incorrects qiuand ils sont vus par un humain. + Par conséquent, les textures d'entrée et l'image du rendu final vont généralement utiliser l'espace colorimétrique + sRGB non-linéaire. +

      + +
      +

      + ℹ️ NOTE: Alors que certains écrans modernes supportent des gammes plus larges comme Display-P3, + les APIs graphiques du web reposent largement sur le sRGB. Les applications utilisant three.js + aujourd'hui utilisent généralement uniquement le sRGB et les espaces colorimétriques sRGB-linéaires. +

      +
      + +

      Rôle des espaces colorimétriques

      + +

      + Workflows linéaires — requis pour les méthodes de rendu modernes — ils impliquent généralement + plus d'un espace de couleur, chacun assigné à un rôle particulier. Les espace colorimétriques linéaires et non-linéaires + sont appropriés pour différents usages, expliqués ci-dessous. +

      + +

      Espaces colorimétriques d'entrée

      + +

      + Les couleurs fournies à three.js — par les sélecteurs de couleurs, les textures, les modèles 3D, et d'autres sources — + ont toutes un espace colorimétrique associé. Celles qui ne sont pas déjà dans l'espace colorimétrique sRGB-Linéaire + doivent-être converties, et les textures doivent recevoir les bonnes consignes de texture.encoding. + Certaines conversions (pour l'héxadecimal et les couleurs CSS en sRGB) peuvent être automatisées si + l'héritage de la gestion des couleurs est désactivé avant l'initialisation des couleurs: +

      + + +THREE.ColorManagement.legacyMode = false; + + +
        +
      • + Matériaux, lumières, et shaders: Les couleurs des matériaux, lumières, et shaders stockent + des composantes RGB dans l'espace colorimétrique sRGB-Linéaire. +
        • +
      • + Vertex colors: [page:BufferAttribute BufferAttributes] stocke + des composantes RGB dans l'espace colorimétrique sRGB-Linéaire. +
        • +
      • + Textures colorées: PNG ou JPEG [page:Texture Textures] contiennent des informations de couleurs + (comme .map ou .emissiveMap) utilisant le domaine fermé de l'espace colorimétrique sRGB, et doivent être annotés avec + texture.encoding = sRGBEncoding. Des formats comme OpenEXR (parfois utilisés par .envMap pi + .lightMap) utilisent l'espace colorimétrique sRGB-Linéaire indiqué par texture.encoding = LinearEncoding, + et peuvent contenir des valeurs du domaine ouvert [0,∞]. +
        • +
      • + Textures non-colorées: Les textures qui ne stockent aucune information de couleur (comme .normalMap + ou .roughnessMap) n'ont pas d'espace colorimétrique associé, et utilisent généralement l'annotation de texture (par défaut) + texture.encoding = LinearEncoding. Dans de rares cas, les données ne concernant pas la couleur + peuvent être représentées par d'autres encodages non-linéaires pour des raisons techniques. +
        • +
      + +
      +

      + ⚠️ ATTENTION: Plusieurs formats de modèles 3D ne définissent par correctement ou de manière cohérente + les informations des espaces colorimétriques. Malgré le fait que three.js tente de gérer la plupart des situations, les problèmes + sont communs avec les formats de fichiers plus anciens. Pour de meilleurs résultats, utilisez glTF 2.0 ([page:GLTFLoader]) + et testez vos modèles 3D dans des visualiseurs en ligne relativement tôt pour vérifier que le modèle est correct en tant que tel. +

      +
      + +

      Espaces colorimétriques fonctionnels

      + +

      + Le rendu, l'interpolation, et plusieurs autres opérations doivent être performées dans un espace colorimétrique + au domaine ouvert, dans lequel les composantes RGB sont proportionnelles + à l'illumination physique. Dans three.js, l'espace colorimétrique est le sRGB-Linéaire. +

      + +

      L'espace colorimétrique de sortie

      + +

      + La sortie d'un écran, d'une image, ou d'une vidéo peut impliquer la conversion depuis un espace colorimétrique + sRGB-Linéaire au domaine ouvert vers un autre espace colorimétrique. Cette conversion peut être effectuée dans + le pass principal du moteur de rendu ([page:WebGLRenderer.outputEncoding]), ou durant le post-processing. +

      + + +renderer.outputEncoding = THREE.sRGBEncoding; // optional with post-processing + + +
        +
      • + Affichage: Les couleurs envoyées à un canvas WebGL pour affichage doivent-être dans l'espace colorimétrique + sRGB. +
        • +
      • + Image: Les couleurs envoyées à une image doivent utiliser l'espace colorimétrique approprié au + format et à l'utilisation. Les images entièrement rendues sur des textures au format PNG ou JPEG + utilisent généralement l'espace colorimétrique sRGB. Les images contenant de l'émission, des light maps, ou d'autres données + qui ne sont pas restreintes à l'intervalle [0,1] utiliseront généralement l'espace colorimétrique sRGB à domaine ouvert, + et un format d'image compatible comme OpenEXR. +
        • +
      + +
      +

      + ⚠️ ATTENTION: Les cibles de rendu doivent utiliser soit le sRGB soit le sRGB-Linéaire. Le sRGB gère + mieux la précision limitée. Dans le domaine fermé, 8 bits suffisent généralement au sRGB + tandis que ≥12 bits (demi float) peuvent être requis pour du sRGB-Linéaire. Si les étapes ultérieures + du pipeline nécessitent une entrée en sRGB-Linéaire, les conversions additionnelles peuvent + avoir un petit impact sur les performances. +

      +
      + +

      Utiliser des instances de THREE.Color

      + +

      + Les méthodes de lecture ou de modification des instances de [page:Color] partent du principe que les données sont déjà + dans l'espace colorimétrique de three.js, le sRGB-Linéaire. Les composantes RGB et HSL sont des représentations + directes de données stockées par l'instance Color, et ne sont jamais converties + implicitement. Les données Color peuvent être explicitement converties avec .convertLinearToSRGB() + ou .convertSRGBToLinear(). +

      + + + // RGB components (no change). + color.r = color.g = color.b = 0.5; + console.log( color.r ); // → 0.5 + + // Manual conversion. + color.r = 0.5; + color.convertSRGBToLinear(); + console.log( color.r ); // → 0.214041140 + + +

      + Avec ColorManagement.legacyMode = false d'activé (recommandé), certaines conversions + sont faites automatiquement. Parce que l'héxadécimal et les couleurs CSS sont généralement en sRGB, les méthodes [page:Color] + vont automatiquement convertir ces entrées du sRGB au sRGB-Linéaire dans des setters, ou + convertir depuis du sRGB-Linéaire au sRGB lors du renvoi de valeurs héxadécimales ou CSS depuis les getters. +

      + + + // Hexadecimal conversion. + color.setHex( 0x808080 ); + console.log( color.r ); // → 0.214041140 + console.log( color.getHex() ); // → 0x808080 + + // CSS conversion. + color.setStyle( 'rgb( 0.5, 0.5, 0.5 )' ); + console.log( color.r ); // → 0.214041140 + + // Override conversion with 'colorSpace' argument. + color.setHex( 0x808080, LinearSRGBColorSpace ); + console.log( color.r ); // → 0.5 + console.log( color.getHex( LinearSRGBColorSpace ) ); // → 0x808080 + console.log( color.getHex( SRGBColorSpace ) ); // → 0xBCBCBC + + +

      Erreurs communes

      + +

      + Quand une couleur ou une texture individuelle est mal configurée, elle apparaîtra plus lumineuse ou plus sombre + qu'attendu. Quand l'espace colorimétrique de sortie du moteur de rendu est mal configuré, la scène entière peut sembler + plus sombre (e.g. conversion manquante vers le sRGB) ou plus lumineuse (e.g. une double conversion vers le sRGB avec du + post-processing). Dans chaque cas le problème peut ne pas être uniforme, et simplement augmenter/diminuer + peut ne pas le résoudre. +

      + +

      + Un problème plus subtil peut se produire quand à la fois l'espace colorimétrique d'entrée et + l'espace colorimétrique de sortie sont incorrects — les niveaux de luminosité globaux peuvent être corrects, mais les couleurs peuvent changer + d'une manière inattendue sous différentes lumières, ou des ombres peuvent sembler plus abruptes et moins lisses + que prévu. Ces deux erreurs assemblées ne forment pas une réussite, et il est important que + l'espace colorimétrique soit linéaire ("scene referred") et que l'espace colorimétrique de sortie soit linéaire + ("display referred"). +

      Créer une scène ([name])

      + +

      L'objectif de cette section est d'effectuer une brève introduction à three.js. Nous commencerons par mettre en place une scène, avec un cube en rotation. Un exemple fonctionnel est fourni à la fin de la page au cas où vous seriez bloqués et que vous auriez besoin d'aide.

      + +

      Avant de commencer

      + +

      Avant de pouvoir utiliser three.js, vous aurez besoin d'un endroit pour l'afficher. Enregistrez le code HTML suivant dans un fichier sur votre ordinateur, ainsi qu'une copie de three.js dans le dossier js/, et ouvrez-le dans votre navigateur.

      + + + <!DOCTYPE html> + <html> + <head> + <meta charset="utf-8"> + <title>My first three.js app</title> + <style> + body { margin: 0; } + </style> + </head> + <body> + <script src="js/three.js"></script> + <script> + // Our Javascript will go here. + </script> + </body> + </html> + + +

      C'est tout. Tout le code qui va suivre doit aller dans la balise <script>.

      + +

      Créer la scène

      + +

      Pour pouvoir afficher quelque chose avec three.js, nous avons besoin de trois choses: une scène, une caméra et un moteur de rendu, afin de pouvoir effectuer un rendu de la scène à travers la caméra.

      + + + const scene = new THREE.Scene(); + const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 ); + + const renderer = new THREE.WebGLRenderer(); + renderer.setSize( window.innerWidth, window.innerHeight ); + document.body.appendChild( renderer.domElement ); + + +

      Prenons un moment pour expliquer ce qu'il se passe. Nous avons maintenant mis en place la scène, notre caméra et le moteur de rendu.

      + +

      Il existe différentes caméras dans three.js. Pour l'instant, utilisons une `PerspectiveCamera`.

      + +

      Le premier attribut est le `field of view`. Le champ de vision (FOV) est l'étendue de la scène visible sur l'écran à un moment donné. La valeur est en degrés.

      + +

      Le second attribut est nommé `aspect ratio`. Vous devrez presque toujours utiliser la largeur de l'élément divisée par sa hauteur, ou vous aurez le même résultat que lorsque vous regardez un vieux film sur une télévision avec un écran large - l'image semble écrasée.

      + +

      Les deux attributs suivants sont le `near` et le `far` du plan de coupe. Les objets plus loins de la caméra que la valeur `far` ou plus proches que `near` ne seront pas rendus. Vous n'avez pas besoin de vous préoccuper de ça pour l'instant, mais vous devriez ajuster ces valeurs dans vos applications afin d'obtenir de meilleures performances.

      + +

      Ensuite vient le moteur de rendu. C'est là où la magie opère. En plus du WebGLRenderer que nous utilisons ici, three.js est livré avec quelques autres moteurs de rendu, principalement utilisés comme moteurs de support pour les utilisateurs avec des navigateurs plus anciens ou n'ayant pas de support de WebGL.

      + +

      En plus d'instancier le moteur de rendu, nous avons aussi besoin de définir la taille à laquelle doit-être effectué le rendu de l'application. Il est recommandé d'utiliser la largeur et la hauteur de la zone qu'est censée occuper l'application - dans ce cas, la largeur et la hauteur de la fenêtre du navigateur. Pour les applications gourmandes en ressources, vous pouvez aussi donner à `setSize` des valeurs plus petites, comme `window.innerWidth/2` et `window.innerHeight/2`, qui permettra d'effectuer le rendu à un quart de sa taille initiale.

      + +

      Si vous souhaitez conserver la taille de votre application mais effectuer un rendu avec une résolution plus faible, vous pouvez le faire appelant `setSize` avec false comme `updateStyle` (le troisième argument). Par exemple, `setSize(window.innerWidth/2, window.innerHeight/2, false)` effectuera un rendu de votre application à demi-résolution, en considérant que votre <canvas> a 100% de largeur et de hauteur.

      + +

      Pour finir, nous ajoutons l'élement `renderer` à notre document HTML. C'est un élément <canvas> que le moteur de rendu utilise pour nous affficher la scène.

      + +

      "C'est sympa tout ça, mais où sont les cubes que tu nous avais promis?" Ajoutons-les maintenant.

      + + + const geometry = new THREE.BoxGeometry( 1, 1, 1 ); + const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } ); + const cube = new THREE.Mesh( geometry, material ); + scene.add( cube ); + + camera.position.z = 5; + + +

      Pour créer un cube, nous avons besoin d'une `BoxGeometry`. C'est un objet qui contient tous les points (`vertices`) et le remplissage (`faces`) du cube. Nous en verrons plus à ce propos dans le futur.

      + +

      En plus de la forme (geometry), nous avons besoin d'un matériau (material) pour le colorer. Three.js contient plusieurs matériaux, mais nous nous contenterons du `MeshBasicMaterial` pour l'instant. Tous les matériaux prennent un objet avec un ensemble de propriétés qui s'appliquent à eux. Pour rester dans la simplicité, ne renseignons qu'un attribut couleur avec la valeur `0x00ff00`, qui est du vert. Cela fonctionne de la même manière que les couleurs en CSS ou dans Photoshop (`hex colors`).

      + +

      La dernière chose dont nous avons besoin est un `Mesh`. Un mesh (maillage) est un objet qui prends une forme (geometry), et qui y applique un matériau (material), que nous pouvons ensuite insérer dans notre scène, et déplacer librement.

      + +

      Par défaut, quand nous appelons `scene.add()`, l'élément est ajouté aux coordonnées `(0,0,0)`. Cela causera la superposition du cube et de la caméra qui seront les uns à l'intérieur des autres. Pour éviter ça, nous devons simplement déplacer un peu la caméra.

      + +

      Faire un rendu de la scène

      + +

      Si vous avez copié le code du dessus dans le fichier HTML créé plus tôt, vous ne verrez rien. C'est parce que nous n'effectuons aucun rendu pour l'instant. Pour cela, nous avons besoin de ce que l'on appelle une `render or animate loop`.

      + + + function animate() { + requestAnimationFrame( animate ); + renderer.render( scene, camera ); + } + animate(); + + +

      Cela va créer une boucle qui va déclencher le moteur de rendu afin qu'il dessine la scène à chaque fois que l'écran est rafraîchi (sur un écran classique c'est 60 fois par secondes). Si l'écriture de jeux sur navigateur vous est étrangère, vous devez vous dire "Pourquoi nous ne créons pas de setInterval ?" C'est que - nous pourrions, mais `requestAnimationFrame` a plusieurs avantages. Le plus important est peut-être qu'il se met en pause lorsque l'utilisateur change d'onglet sur son navigateur, par conséquence, pas de perte de leur précieuse puissance de calcul ou de durée de vie de leur batterie.

      + +

      Animer le cube

      + +

      Si vous insérez tout le code au-dessus dans le fichier que vous avez créé avant que nous commencions, vous devriez voir un cube vert. Rendons tout ça un peu plus intéressant en le faisant tourner.

      + +

      Ajoutez le code suivant juste au dessus de l'appel `renderer.render` dans votre fonction `animate`:

      + + + cube.rotation.x += 0.01; + cube.rotation.y += 0.01; + + +

      Ceci sera exécuté à chaque frame (normalement 60 fois par secondes), et donnera au cube une belle animation de rotation. Pour résumer, tout ce que vous souhaitez déplacer ou changer pendant que l'application est en cours d'exécution doit passer par la boucle animate. Vous pouvez évidemment appeler d'autres fonctions depuis cet endroit, afin de ne pas finir avec une fonction `animate` de plusieurs centaines de lignes.

      + +

      Le résultat

      +

      Félicitations! Vous avez maintenant terminé votre première application three.js. C'est trivial, mais il faut bien commencer quelque part.

      Créer un texte ([name])

      +
      +

      + Parfois vous aurez besoin d'utiliser du texte dans votre application three.js - ici + sont présentées quelques façons de le faire. +

      +
      + +

      1. DOM + CSS

      +
      +

      + Utiliser du HTML est généralement la manière la plus simple et la plus rapide d'ajouter du texte. Ceci est la méthode + utilisée pour les overlays descriptifs de la plupart des exemples three.js. +

      +

      Vous pouvez ajouter du contenu à une

      + <div id="info">Description</div> + +

      + et utiliser CSS pour donner une position absolute située au-dessus de tout le reste du contenu grâce au + z-index plus particulièrement si vous utilisez three.js en plein-écran. +

      + + +#info { + position: absolute; + top: 10px; + width: 100%; + text-align: center; + z-index: 100; + display:block; +} + + +
      + + +

      2. Utiliser [page:CSS2DRenderer] ou [page:CSS3DRenderer]

      +
      +

      + Utilisez ces moteurs de rendu pour dessiner des textes de haute-qualité contenus dans l'élément DOM de vos scène three.js. + Cette approche est similaire à la 1. excepté qu'avec ces moteurs de rendu les éléments peuvent être intégrés plus précisément et dynamiquement à la scène. +

      +
      + + +

      3. Associer un texte au canvas et l'utiliser comme [page:Texture]

      +
      +

      Utilisez cette méthode si vous souhaitez dessiner du texte facilement sur un plane dans votre scène three.js.

      +
      + + +

      4. Créez un modèle dans votre application 3D préférée et exportez le dans three.js

      +
      +

      Utilisez cette méthode si vous préférez travailler avec vos applications 3D puis importer vos modèles dans three.js.

      +
      + + +

      5. Forme de texte procédurale

      +
      +

      + Si vous souhaitez travailler en three.js pur ou créer des formes de texte 3D procédurales et dynamiques, + vous pouvez créer un mesh qui aura pour geometry une instance de THREE.TextGeometry: +

      +

      + new THREE.TextGeometry( text, parameters ); +

      +

      + Pour que cela fonctionne, dans tous les cas, votre TextGeometry aura besoin d'une instance de THREE.Font + avec comme paramètre "font". + + Voir [page:TextGeometry] pour avoir plus d'informations sur comment cela peut-être mis en place, une description de chaque + paramètre accepté, et une liste des fonts JSON qui viennent avec la distribution THREE.js. +

      + +

      Exemples

      + +

      + [example:webgl_geometry_text WebGL / geometry / text]
      + [example:webgl_shadowmap WebGL / shadowmap] +

      + +

      + Si Typeface ne fonctionne pas, ou que vous souhaitez une font qui n'est pas ici, il y a un tutoriel + avec un script python pour blender qui vous permet d'exporter du texte dans au format JSON de Three.js: + [link:http://www.jaanga.com/2012/03/blender-to-threejs-create-3d-text-with.html] +

      + +
      + + +

      6. Fonts Bitmap

      +
      +

      + BMFonts (bitmap fonts) permet de transformer les lots de glyphs en une seule BufferGeometry. Le rendu BMFont + supporte les sauts-de-ligne, l'espacement des lettres, le crénage, les fonctions de distance signée avec + des dérivées, les fonctions de distance signée multi-channel, les fonts multi-texture, et bien plus. + Voir [link:https://github.com/felixmariotto/three-mesh-ui three-mesh-ui] ou [link:https://github.com/Jam3/three-bmfont-text three-bmfont-text]. +

      +

      + Les fonts de base sont disponibles dans des projets comme + [link:https://github.com/etiennepinchon/aframe-fonts A-Frame Fonts], ou vous pouvez créer la votre + depuis n'importe quelle font .TTF, en optimisant les performances en n'incluant que les character requis par le projet. +

      +

      + Quelques outils utiles: +

      7. Troika Text

      +
      +

      + Le package [link:https://www.npmjs.com/package/troika-three-text troika-three-text] effectue un rendu + de qualité et anti-alisé des textes, utilisant une technique similaire à BMFonts, mais fonctionne directement avec n'importe quel fichier de font .TTF + ou .WOFF pour que vous n'ayez pas à pré-générer une texture glyph hors-ligne. Il ajoute également des fonctionnalités + comme: +

      +
        +
      • Des effets comme les strokes, les ombres portées, et les courbures
        • +
      • La capacité d'appliquer n'importe quel matériau three.js, même un ShaderMaterial customisé
        • +
      • Le support des ligatures de fonts, des scripts pour les lettres jointes, et un layout bi-directionnel de droite-à-gauche
        • +
      • Une optimisation pour les grandes quantités de textes dynamiques, en réalisant la plupart du travail en dehors du thread principal dans un web worker

      Dessiner des lignes ([name])

      +
      +

      + Disons que vous voulez dessiner une ligne ou un cercle, pas un wireframe [page:Mesh]. + Premièrement nous devons préparer le [page:WebGLRenderer renderer], [page:Scene scene] et la caméra (voir la page Créer une scène). +

      + +

      Voici le code que nous allons utiliser:

      + +const renderer = new THREE.WebGLRenderer(); +renderer.setSize( window.innerWidth, window.innerHeight ); +document.body.appendChild( renderer.domElement ); + +const camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 500 ); +camera.position.set( 0, 0, 100 ); +camera.lookAt( 0, 0, 0 ); + +const scene = new THREE.Scene(); + +

      La prochaine chose que nous allons faire est définir un matériau (material). Pour les lignes, nous devons utiliser [page:LineBasicMaterial] ou [page:LineDashedMaterial].

      + +//create a blue LineBasicMaterial +const material = new THREE.LineBasicMaterial( { color: 0x0000ff } ); + + +

      + Après le matériau, nous devons utiliser une forme (geometry) avec quelques sommets: +

      + + +const points = []; +points.push( new THREE.Vector3( - 10, 0, 0 ) ); +points.push( new THREE.Vector3( 0, 10, 0 ) ); +points.push( new THREE.Vector3( 10, 0, 0 ) ); + +const geometry = new THREE.BufferGeometry().setFromPoints( points ); + + +

      Notez que les lignes sont tracées entre chaque paire consécutive de sommets, mais pas entre la première et la deuxième (la ligne n'est pas fermée).

      + +

      Maintenant que nous avons les points pour deux lignes et un matériau, nous pouvons les assembler pour former une ligne.

      + +const line = new THREE.Line( geometry, material ); + +

      Il ne manque qu'à l'ajouter à la scène et appeler [page:WebGLRenderer.render render].

      + + +scene.add( line ); +renderer.render( scene, camera ); + + +

      Vous devez maintenant voir une flèche pointant vers le haut, faite de deux lignes bleues.

      Quel format de modèle 3D est le mieux supporté?

      +
      +

      + Le format recommandé pour l'import et l'export de modèles est glTF (GL Transmission Format). Parce que glTF est ciblé sur la rapidité du temps d'exécution, le format est compact et rapide à charger. +

      +

      + three.js fournit des loaders pour plusieurs autres formats populaires comme FBX, Collada ou OBJ. Néanmoins, vous devez toujours essayer d'établir un workflow basé sur glTF dans vos projets. Pour plus d'informations, voir [link:#manual/introduction/Loading-3D-models loading 3D models]. +

      +
      + +

      Pourquoi y a-t-il des tags meta viewport dans les exemples?

      +
      + <meta name="viewport" content="width=device-width, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0"> + +

      Ces tags contrôlent la taille du viewport et l'échelle pour les navigateurs mobiles (où le contenu de la page peut être rendu à des tailles différentes de celle du viewport visible).

      + +

      +
      + +

      Comment conserver l'échelle de la scène au resize?

      +

      + Nous voulons que tous les objets, peu importe leur distance à la caméra, conservent leur taille, même si la fenêtre est redimensionnée. + + L'équation clé pour résoudre ce problème est la formule suivante, concernant la hauteur visible à une distance donnée: + + +visible_height = 2 * Math.tan( ( Math.PI / 180 ) * camera.fov / 2 ) * distance_from_camera; + + Si nous augmentons la hauteur de la fenêtre d'un certain pourcentage, alors nous souhaitons que la hauteur visible à toutes distances soit augmentée + du même pourcentage. + + Cela ne peut pas être fait en changeant la position de la camera. Il faut plutôt changer le champ de vision de celle-ci. + [link:http://jsfiddle.net/Q4Jpu/ Example]. +

      + +

      Pourquoi une partie de mon objet est invisible?

      +

      + Cela peut être causé par le face culling. Les faces ont une orientation qui décident quel côté est lequel. Et le culling retire la face arrière dans des circonstances normales. Pour voir si c'est bien votre problème, changez la propriété material side pour THREE.DoubleSide. + material.side = THREE.DoubleSide +

      + +

      Pourquoi three.js retourne quelques fois des valeurs étranges pour des inputs invalides?

      +

      + Pour des raisons de performances, three.js ne valide pas les inputs dans la plupart des cas. Il en va de la responsabilité de votre application de vérifier que tous les inputs sont valides. +

      Créer du contenu VR ([name])

      + +

      + Ce guide fournit une brève vue d'ensemble des composants basiques d'une application VR web + faite avec three.js. +

      + +

      Workflow

      + +

      + Premièrement, vous devez inclure [link:https://github.com/mrdoob/three.js/blob/master/examples/jsm/webxr/VRButton.js VRButton.js] + dans votre projet. +

      + + +import { VRButton } from 'three/addons/webxr/VRButton.js'; + + +

      + *VRButton.createButton()* fait deux choses importantes: Cela crée un bouton qui indique + la compatibilité VR. De plus, cela initie une session VR si l'utilisateur active le bouton. La seule chose que vous avez + à faire est d'ajouter la ligne de code suivante à votre application. +

      + + +document.body.appendChild( VRButton.createButton( renderer ) ); + + +

      + Ensuite, vous devez dire à votre instance de `WebGLRenderer` d'activer le rendu XR. +

      + + +renderer.xr.enabled = true; + + +

      + Finalement, vous n'avez plus qu'à ajuster votre boucle d'animation étant donné que nous ne pouvons pas utiliser notre fonction bien aimée + *window.requestAnimationFrame()*. Pour les projets VR nous utilisons [page:WebGLRenderer.setAnimationLoop setAnimationLoop]. + Le code minimal ressemble à cela: +

      + + +renderer.setAnimationLoop( function () { + + renderer.render( scene, camera ); + +} ); + + +

      Supprimer un objet ([name])

      + +

      + Un des aspects importants dans l'amélioration des performances et qui permet d'éviter les fuites de mémoire dans votre application est la suppression des entités non-utilisées de la librairie. + Dès que vous créez une instance d'un type *three.js*, vous allouez une certaine quantité de mémoire. Toutefois, *three.js* crée pour certains objets + comme les formes ou les matériaux, des entités WebGL associées comme des buffers ou des programmes de shaders qui sont nécessaires au rendu. Il est important de + souligner que ces objets ne sont pas automatiquement débarassés. Au contraire, l'application doit utiliser une API particulière pour libérer ce genre de ressources. + Ce guide vous fournit une brève vue d'ensemble du fonctionnement de cette API et des objets considérés comme pertinents dans ce contexte. +

      + +

      Formes

      + +

      + Une forme représente généralement des informations concernant des sommets présentés comme un ensemble d'attributs. *three.js* crée en interne un objet de type [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLBuffer WebGLBuffer] + pour chaque attribut. Ces entités sont supprimées uniquement si vous appelez [page:BufferGeometry.dispose](). Si une forme devient obsolète dans votre application, + exécutez cette méthode pour libérer toutes les ressources associées. +

      + +

      Matériaux

      + +

      + Un matériau définit comment un objet est rendu. *three.js* utilise les informations de la définition du matériau pour construire un programme de shader pour le rendu. + Les programmes de shader peuvent être supprimés seulement si leur matériau respectif est supprimé. Dans un souci de performances, *three.js* essaye de réutiliser des + programmes de shaders existants si possible. Donc un programme de shader est supprimé uniquement si tous les matériaux associés sont supprimés. Vous pouvez indiquer la suppression d'un matériau en + exécutant [page:Material.dispose](). +

      + +

      Textures

      + +

      + La suppression d'un matériau n'a aucun effet sur les textures. Elles sont gérées séparément étant donné qu'une seule texture peut-être utilisée par plusieurs matériaux au même moment. + Chaque fois que vous créez une instance de [page:Texture], three.js crée en interne une instance de [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLTexture WebGLTexture]. + Comme les buffers, cet objet ne peut-être supprimé qu'en appelant [page:Texture.dispose](). +

      + +

      + Si vous utilisez une `ImageBitmap` comme source de données pour une texture, vous devez appeler [link:https://developer.mozilla.org/en-US/docs/Web/API/ImageBitmap/close ImageBitmap.close]() au niveau de l'application pour libérer toutes les ressources côté processeur. + Un appel automatisé de `ImageBitmap.close()` dans [page:Texture.dispose]() n'est pas possible, étant donné que le bitmap devient inutilisable, et que le moteur n'a aucun moyen de savoir si l'image bitmap est utilisée ailleurs. +

      + +

      Cibles de rendu

      + +

      + Les objets de type [page:WebGLRenderTarget] n'allouent pas qu'une instance de [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLTexture WebGLTexture] mais également + [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLFramebuffer WebGLFramebuffer]s et [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderbuffer WebGLRenderbuffer]s + pour réaliser des rendus customisés. Ces objets ne sont désalloués qu'en exécutant [page:WebGLRenderTarget.dispose](). +

      + +

      Divers

      + +

      + Il y a d'autres classes du dossier example comme controls ou les effets de post processings qui fournissent la méthode `dispose()` pour retirer des event listeners internes + ou des cibles de rendu. En général, il est recommandé de jeter un coup d'oeil à l'API ou à la documentation d'une classe en cherchant un `dispose()`. Si il existe, vous devez l'utiliser pour faire votre petit ménage après utilisation. +

      + +

      FAQ

      + +

      Pourquoi *three.js* ne peut pas supprimer automatiquement les objets?

      + +

      + Cette question a été posée énormément de fois par la communauté, il est donc important de clarifier ce sujet. Le fait est que *three.js* ne connaît pas la durée de vie ou la portée des + entités comme les formes ou les matériaux créés par les utilisateurs. Il en va de la responsabilité de l'application. Par exemple, si un matériau n'est pas utilisé pour le rendu pour l'instant, + il peut être nécessaire pour le prochain frame. Donc si l'application décide qu'un certain objet peut-être supprimé, elle doit en notifier le moteur en appelant la méthode + `dispose()`. +

      + +

      Retirer un mesh de la scène supprime également sa forme et son matériau?

      + +

      + Non, vous devez explicitement supprimer la forme et le matériau via *dispose()*. Gardez à l'esprit que les formes et matériaux peuvent être partagés entre plusieurs objets 3D comme les meshes. +

      + +

      Est-ce que *three.js* fournit des informations à propos des objets en cache?

      + +

      + Oui. Il est possible d'interroger [page:WebGLRenderer.info], qui est une propriété spéciale du moteur de rendu avec une série d'informations et de statistiques à propos de l'usage graphique + et du proccessus de rendu. Entre autres, cela peut vous donner des informations comme le nombre de textures, de formes et de programmes de shaders stockés en interne. Si vous remarquez des problèmes de performance + dans votre application, une bonne idée serait de débugger cette propriété pour facilement identifier une fuite de mémoire. +

      + +

      Que se passe t-il quand on appelle `dispose()` sur une texture mais que l'image n'est pas encore chargée?

      + +

      + Des ressources internes sont allouées pour une texture uniquement si l'image est entièrement chargée. Si vous supprimez une texture avant que l'image soit chargée, + rien ne se produit. Aucune ressource n'était allouée il n'y a donc rien à libérer. +

      + +

      Que se passe t-il quand on appelle `dispose()` puis qu'on utilise l'objet plus tard?

      + +

      + Les ressources internes libérées sont réallouées par le moteur. Il n'y aura donc pas d'erreur d'exécution mais vous remarquerez probablement un impact négatif sur les performances au frame actuel, + particulièrement quand le programme de shaders doit-être compilé. +

      + +

      Comment gérer les objets *three.js* dans mon application? Quand dois-je supprimer les objets?

      + +

      + En général, il n'y a pas de recommandation universelle pour cette question. Savoir si l'utilisation de `dispose()` est appropriée dépend grandement des cas d'utilisation. Il est important de souligner qu'il + n'est pas nécessaire de toujours se débarasser des objets. Un bon exemple serait un jeu avec de multiple niveaux. Le bon moment pour supprimer les objets serait à un changement + de niveau. L'application devrait traverser les anciennes scènes et supprimer tous les matériaux, les formes et les textures obsolètes. Comme mentionné dans la section précédente, supprimer des + objets toujours utilisés ne produit pas d'erreur d'exécution. La pire chose qui pourrait se produire serait une baisse de la performance à un seul frame. +

      + +

      Mettre les éléments à jour ([name])

      +
      +

      Tous les objets mettent par défaut automatiquement leur matrice à jour si ils ont été ajoutés dans la scène avec

      + +const object = new THREE.Object3D(); +scene.add( object ); + + ou si ils sont l'enfant d'un autre objet qui a été ajouté à la scène: + +const object1 = new THREE.Object3D(); +const object2 = new THREE.Object3D(); + +object1.add( object2 ); +scene.add( object1 ); //object1 and object2 will automatically update their matrices + +
      + +

      Cependant, si vous savez que l'objet va être statique, vous pouvez désactiver ce comportement et mettre la matrice à jour manuellement quand le besoin se présente.

      + + +object.matrixAutoUpdate = false; +object.updateMatrix(); + + +

      BufferGeometry

      +
      +

      + Les BufferGeometries stockent des informations comme (la position des sommets, l'indice des faces, les normales, les couleurs, + les UVs et tout autre attribut customisé) dans [page:BufferAttribute buffers] - c'est un, + [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays typed arrays]. + Ceci les rend généralement plus rapides que les Geometries standard, le contrecoup est qu'il est plus difficile de les + utiliser. +

      +

      + En ce qui concerne la mise à jour des BufferGeometries, la chose la plus importante à comprendre est que + vous ne pouvez pas changer la taille des buffers (c'est très coûteux, en réalité, c'est équivalent à créer une nouvelle forme). + Vous pouvez toutefois mettre à jour le contenu des buffers. +

      +

      + Ce qui signifie que si vous savez qu'un attribut de votre BufferGeometry va augmenter, disons le nombre de sommets, + vous devez pré-allouer un buffer assez grand pour contenir n'importe quel nouveau sommet qui pourra être créé. Évidemment, + cela signifie également qu'il y aura une taille maximale pour votre BufferGeometry - il n'y a + aucun moyen de créer une BufferGeometry qui peut être étendue à l'infini d'une manière efficiente. +

      +

      + Nous utiliserons l'exemple d'une ligne qui est étendue à chaque rendu. Nous allouerons de l'espace + dans le buffer pour 500 sommets mais nous n'en dessinerons que deux au début, en utilisant [page:BufferGeometry.drawRange]. +

      + +const MAX_POINTS = 500; + +// geometry +const geometry = new THREE.BufferGeometry(); + +// attributes +const positions = new Float32Array( MAX_POINTS * 3 ); // 3 vertices per point +geometry.setAttribute( 'position', new THREE.BufferAttribute( positions, 3 ) ); + +// draw range +const drawCount = 2; // draw the first 2 points, only +geometry.setDrawRange( 0, drawCount ); + +// material +const material = new THREE.LineBasicMaterial( { color: 0xff0000 } ); + +// line +const line = new THREE.Line( geometry, material ); +scene.add( line ); + +

      + Ensuite nous ajouterons aléatoirement des points à l'aide d'un pattern comme: +

      + +const positions = line.geometry.attributes.position.array; + +let x, y, z, index; +x = y = z = index = 0; + +for ( let i = 0, l = MAX_POINTS; i < l; i ++ ) { + + positions[ index ++ ] = x; + positions[ index ++ ] = y; + positions[ index ++ ] = z; + + x += ( Math.random() - 0.5 ) * 30; + y += ( Math.random() - 0.5 ) * 30; + z += ( Math.random() - 0.5 ) * 30; + +} + +

      + If you want to change the number of points rendered after the first render, do this: +

      + +line.geometry.setDrawRange( 0, newValue ); + +

      + If you want to change the position data values after the first render, you need to + set the needsUpdate flag like so: +

      + +line.geometry.attributes.position.needsUpdate = true; // required after the first render + + +

      + If you change the position data values after the initial render, you may need to recompute + bounding volumes so other features of the engine like view frustum culling or helpers properly work. +

      + +line.geometry.computeBoundingBox(); +line.geometry.computeBoundingSphere(); + + +

      + [link:https://jsfiddle.net/t4m85pLr/1/ Here is a fiddle] showing an animated line which you can adapt to your use case. +

      Materiaux

      Toutes les valeurs uniformes peuvent être changées librement(e.g. couleurs, textures, opacité, etc), les valeurs sont envoyées aux shaders à chaque frame.

        • +
      + +

      Des changements dans ces propriétés exigent la création d'un nouveau programme de shader. Vous devrez définir

      + material.needsUpdate = true + +

      Gardez à l'esprit que cela risque d'être assez lent et de causer des saccades dans le framerate (particulièrement sur Windows, étant donné que la compilation de shader est plus lente dans DirectX que dans OpenGL).

      + +

      Pour des expériences pluis fluides vous pouvez émuler des changements dans ces fonctionnalités pour qu'elles contiennent un genre de valeurs "factices" comme zéro en intensité de lumières, des textures blanches ou zéro brouillard.

      + +

      Vous pouvez librement changer le matériau utilisé pour les différents morceaux de formes, mais pas comment un objet est divisé en morceaux (selon le matériau des faces).

      + +

      Si vous avez besoin d'avoir différentes configurations de matériaux durant l'exécution:

      +

      Si le nombre de matériaux / morceaux est petit, vous pouvez pré-diviser l'objet préalablement (e.g. cheveux / visage / corps / vêtements supérieurs / pantalon pour un humain, avant / côtés / toit / fenêtres / pneu / intérieur pour une voiture.).

      + +

      Si le nombre est grand (e.g. chaque face peut potentiellement être différente), songez à utiliser une autre solution, comme l'utilisation d'attributs / textures pour avoir une apparence différente par face.

      + +

      Exemples

      +

      + [example:webgl_materials_car WebGL / materials / car]
      + [example:webgl_postprocessing_dof WebGL / webgl_postprocessing / dof] +

      +
      + + +

      Textures

      +
      +

      Les images, canvas, vidéos et les données des textures doivent avoir le flag suivant si elles sont changées:

      + + texture.needsUpdate = true; + +

      La cible du rendu se met automatiquement à jour.

      + +

      + [example:webgl_materials_video WebGL / materials / video]
      + [example:webgl_rtt WebGL / rtt] +

      + + +

      Caméras

      Utiliser le post-processing ([name])

      + +

      + Plusieurs applications three.js effectuent un rendu de leurs objets 3D directement dans la scène. Parfois, vous souhaitez appliquer un ou plusieurs + effects graphiques comme la profondeur de champ, le flou lumineux, du grain, ou différents types d'Anti-aliasing. Le post-processing est une approche très utilisée + pour implémenter de tels effets. Premièrement, la scène est rendue dans une cible de rendu qui représente un buffer dans la mémoire de la carte vidéo. + A la prochaine étape un ou plusieurs effets de post-processing appliquent des filtres au buffer de l'image qui est finalement rendue à + l'écran. +

      +

      + three.js fournit une solution complète de post-processing via [page:EffectComposer] pour implémenter un tel workflow. +

      + +

      Workflow

      + +

      + La première étape est d'importer tous les fichiers nécessaires du dossier exemple. Le guide part du principe que vous utilisez le + [link:https://www.npmjs.com/package/three npm package] officiel de three.js. Pour notre démo basique, nous avons besoin des fichiers suivants. +

      + + + import { EffectComposer } from 'three/addons/postprocessing/EffectComposer.js'; + import { RenderPass } from 'three/addons/postprocessing/RenderPass.js'; + import { GlitchPass } from 'three/addons/postprocessing/GlitchPass.js'; + + +

      + Après avoir importé tous les fichiers correctement, nous pouvons créer notre composer en lui passant une instance de [page:WebGLRenderer]. +

      + + + const composer = new EffectComposer( renderer ); + + +

      + Lors de l'utilisation d'un composer, il est nécessaire de changer la boucle d'animation de l'application. Au lieu d'appeler la méthode de rendu + [page:WebGLRenderer], nous devons utiliser appeler [page:EffectComposer]. +

      + + + function animate() { + + requestAnimationFrame( animate ); + + composer.render(); + + } + + +

      + Notre composer est maintenant prêt, il est donc possible de configurer la chaîne d'effets de post-processing. Ces effets (passes) sont chargés de la création + de l'apparence visuelle finale de l'application. Ils sont traités dans l'ordre de leur ajout/insertion. Dans notre example, l'instance de `RenderPass` + est exécutée en première, puis l'instance de `GlitchPass` est exécutée. Le dernier effet activé de la chaîne est automatiquement rendu dans la scène. Le setup + des effets ressemble à ça: +

      + + + const renderPass = new RenderPass( scene, camera ); + composer.addPass( renderPass ); + + const glitchPass = new GlitchPass(); + composer.addPass( glitchPass ); + + +

      + `RenderPass` est normalement placé au début de la chaîne pour fournir la scène rendue en tant qu'entrée pour les prochaines étapes de post-processing. Dans notre cas, + `GlitchPass` va utiliser les données de l'image pour appliquer un effet de glitch. Regardez cet [link:https://threejs.org/examples/webgl_postprocessing_glitch exemple live] + pour voir cela en action. +

      + +

      Effets Intégrés

      + +

      + Vous pouvez utiliser une large palette d'effets de post-processing pré-définis fournis par le moteur. Ils se trouvent dans le dossier + [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm/postprocessing postprocessing]. +

      + +

      Effets Customisés

      + +

      + Parfois vous voulez écrire un shader de post-processing customisé et l'inclure dans les effets (passes) de post-processing. Dans ce scénario, + vous pouvez utiliser `ShaderPass`. Après avoir importé le fichier et votre shader customisé, vous pouvez utiliser le code suivant pour mettre en place l'effet (pass). +

      + + + import { ShaderPass } from 'three/addons/postprocessing/ShaderPass.js'; + import { LuminosityShader } from 'three/addons/shaders/LuminosityShader.js'; + + // later in your init routine + + const luminosityPass = new ShaderPass( LuminosityShader ); + composer.addPass( luminosityPass ); + + +

      + Ce repository fournit un fichier appelé [link:https://github.com/mrdoob/three.js/blob/master/examples/jsm/shaders/CopyShader.js CopyShader] qui est + une bonne base de code pour créer votre propose shader customisé. `CopyShader` copie simplement le contenu de l'image du buffer de l'[page:EffectComposer] + à son buffer d'écriture sans y appliquer aucun effet. +

      [name]

      + +

      + Vous pouvez installer three.js avec [link:https://www.npmjs.com/ npm] et d'autres outils de build modernes, ou commencer rapidement avec just un hébergement static ou un CDN. Pour la plupart des utilisateurs, installer depuis npm est le meilleur choix. +

      + +

      + Peu importe votre choix, soyez cohérents et importez tous vos fichiers avec la même version de la librairie. Mélanger des fichiers de différentes sources peut causer une duplication de certaines parties de code, ou même casser l'application d'une manière imprédictible. +

      + +

      + Toutes les méthodes d'installation de three.js dépendent des Modules ES (voir [link:https://eloquentjavascript.net/10_modules.html#h_hF2FmOVxw7 Eloquent JavaScript: ECMAScript Modules]), ce qui vous permet d'inclure uniquement les parties requises de la librairie dans le projet final. +

      + +

      Installer depuis npm

      + +

      + Pour installer le module npm [link:https://www.npmjs.com/package/three three], ouvrez une fenêtre de terminal dans le dossier de votre projet et lancez la commande suivante: +

      + + + npm install three + + +

      + Le package sera téléchargé et installé. Puis vous pouvez l'importer dans votre projet: +

      + + + // Option 1: Import the entire three.js core library. + import * as THREE from 'three'; + + const scene = new THREE.Scene(); + + + // Option 2: Import just the parts you need. + import { Scene } from 'three'; + + const scene = new Scene(); + + +

      + En l'installant depuis npm, vous utiliserez quasiment toujours une sorte de [link:https://eloquentjavascript.net/10_modules.html#h_zWTXAU93DC bundling tool] pour combiner tous les packages dont votre projet a besoin en un seul fichier JavaScript. N'importe quel bundler JavaScript modern peut être utilisé avec three.js, le choix le plus populaire est [link:https://webpack.js.org/ webpack]. +

      + +

      + Toutes les fonctionnalités ne sont pas directement accédées depuis le module three (également appelé "bare import"). D'autres parties populaires de la librairie — comme les contrôles, les loaders, et les effets de post-processing — doivent être importés depuis le sous-dossier [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm examples/jsm]. Pour en apprendre plus, consulter Examples ci-dessous. +

      + +

      + Apprenez-en plus à propos des modules npm depuis [link:https://eloquentjavascript.net/20_node.html#h_J6hW/SmL/a Eloquent JavaScript: Installation avec npm]. +

      + +

      Installer depuis un CDN ou un hébergement statique

      + +

      + La librairie three.js peut être utilisée sans aucun build system, soit en uploadant les fichiers sur votre propre server web ou en utilisant un CDN existant. Parce que la librairie repose sur les modules ES, n'importe quel script qui y fait référence doit utiliser le type="module" comme montré ci-dessous. + Il est également requis de définir une Import Map qui effectue la résolution du bare module specifier `three`. +

      + + + <script async src="https://unpkg.com/es-module-shims@1.3.6/dist/es-module-shims.js"></script> + + <script type="importmap"> + { + "imports": { + "three": "https://unpkg.com/three@<version>/build/three.module.js" + } + } + </script> + + <script type="module"> + + import * as THREE from 'three'; + + const scene = new THREE.Scene(); + + </script> + + +

      + Étant donné que les Import maps ne sont pas encore supportées par tous les navigateurs, il est nécessaire d'ajouter le polyfill *es-module-shims.js*. +

      + +

      Addons

      + +

      + Le noyau de three.js est concentré sur les composants les plus importans d'un moteur 3D. Plusieurs autres composants utiles - comme les contrôles, les loaders, et les effets de post-processing - font partie du dossier [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm examples/jsm]. Ils sont désignés comme "exemples", parce que, en plus de pouvoir les utiliser directement tel qu'ils sont, ils sont aussi supposés être remixés et customisés. Ces composants sont toujours synchronisés avec le noyau de la librarie, là où des packages tiers similaires sur npm sont maintenus par différentes personnes et peuvent ne pas être à jour. +

      + +

      + Les addons n'ont pas besoin d'être installés séparément, mais doivent être importés séparément. Si three.js a été installé avec npm, vous pouvez charger le composant [page:OrbitControls] avec: +

      + + + + import { OrbitControls } from 'three/addons/controls/OrbitControls.js'; + + const controls = new OrbitControls( camera, renderer.domElement ); + + +

      + Si three.js a été installé depuis un CDN, utilisez le même CDN pour installer d'autres composants: +

      + + + <script async src="https://unpkg.com/es-module-shims@1.3.6/dist/es-module-shims.js"></script> + + <script type="importmap"> + { + "imports": { + "three": "https://unpkg.com/three@<version>/build/three.module.js", + "three/addons/": "https://unpkg.com/three@<version>/examples/jsm/" + } + } + </script> + + <script type="module"> + + import * as THREE from 'three'; + import { OrbitControls } from 'three/addons/controls/OrbitControls.js'; + + const controls = new OrbitControls( camera, renderer.domElement ); + + </script> + + +

      + Il est important que tous les fichiers utilisent la même version. N'importez pas différents addons de différentes versions, ou n'utilisez pas d'addons d'une version de three.js différente de celle de la librarie elle-même. +

      + +

      Compatibilité

      + +

      Imports CommonJS

      + +

      + Alors que la plupart des bundlers JavaScript modernes supportent les modules ES par défaut, cela peut ne pas être le cas de certains build tools plus anciens. Dans ce cas, vous pouvez probablement configurer le bundler pour qu'il comprenne les modules ES: [link:http://browserify.org/ Browserify] a just besoin du plugin [link:https://github.com/babel/babelify babelify], par exemple. +

      + +

      Node.js

      + +

      + Parce que three.js est construit pour le web, il dépend de navigateurs et d'APIs DOM qui n'existent pas toujours dans Node.js. Certains de ces problèmes peuvent être résolus en utilisant des morceaux de code comme [link:https://github.com/stackgl/headless-gl headless-gl], ou en remplaçant des composents comme [page:TextureLoader] avec des alternatives customisées. D'autres APIs DOM peuvent être profondément entrelacées avec le code qui les utilises, et il sera compliqué de le modifier. Nous soutenons les pull requests simples et maintenables pour améliorer le support de Node.js, mais recommendons d'ouvrir une issue pour parler de vos améliorations avant. +

      + +

      + Faites attention à bien ajouter `{ "type": "module" }` à votre `package.json` pour autoriser les modules ES6 dans votre projet Node. +

      Importer des modèles 3D ([name])

      + +

      + Les modèles 3D sont disponibles dans des centaines de formats, chacun ayant des objectifs + différents, des fonctionnalités assorties, et une complexité variable. Même si + + three.js fournit plusieurs loaders, choisir le bon format et + workflow vous fera gagner du temps et vous épargnera beaucoup de frustration par la suite. Certains formats sont + difficiles à appréhender, inefficaces pour les exépriences en temps-réel, ou simplement + pas entièrement supportés pour le moment. +

      + +

      + Ce guide vous fournit un workflow recommandé pour la plupart des utilisateurs, et des suggestions + concernant quoi essayer si les choses ne se déroulent pas comme prévu. +

      + +

      Avant de commencer

      + +

      + Si vous n'êtes pas familier avec le fait de lancer un serveur local, commencez par + [link:#manual/introduction/How-to-run-things-locally how to run things locally]. + Plusieurs erreurs communes concernant les modèles 3D peuvent-être évitées en hébergeant les fichiers + correctement. +

      + +

      Workflow recommandé

      + +

      + Dans la mesure du possible, nous recommandons l'utilisation de glTF (GL Transmission Format). Les versions + .GLB et .GLTF du format sont + bien supportées. Étant-donné que glTF se concentre sur la réduction du temps d'exécution du chargement des modèles, il est + compact et rapide à transmettre. Les fonctionnalités inclusent sont les meshes, les matériaux, + les textures, les skins, les squelettes, les morph targets, les animations, les lumières, et les + caméras. +

      + +

      + Les fichiers glTF appartenant au domaine public sont disponibles sur des sites comme + + Sketchfab, différents outils incluent l'export de glTF: +

      + + + +

      + Si votre outil de prédilection n'inclut pas le support des glTF, pensez à demander + aux auteurs d'inclure l'export des glTF, ou postez sur + the glTF roadmap thread. +

      + +

      + Quand glTF n'est pas utilisable, des formats populaires comme FBX, OBJ, ou COLLADA + sont également disponibles et régulièrement maintenus. +

      + +

      Charger les modèles

      + +

      + Seulement quelques loaders (e.g. [page:ObjectLoader]) sont inclus par défaut dans + three.js — les autres doivent être ajoutés individuellement à votre application. +

      + + + import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'; + + +

      + Une fois que vous avez importé un loader, vous pouvez ajouter un modèle à votre scène. La syntaxe varie selon + les loaders — quand vous utilisez un autre format, jetez un oeil à la documentation de ce + loader. Pour glTF, l'utilisation avec des scripts globaux doit-être: +

      + + + const loader = new GLTFLoader(); + + loader.load( 'path/to/model.glb', function ( gltf ) { + + scene.add( gltf.scene ); + + }, undefined, function ( error ) { + + console.error( error ); + + } ); + + +

      + Voir [page:GLTFLoader GLTFLoader documentation] pour plus de détails. +

      + +

      Dépannage

      + +

      + Vous avez passé des heures à modeler votre chef-d'oeuvre artisanal, vous le chargez sur + la page web, et — oh non! 😭 Il est tordu, mal coloré, ou tout simplement porté-disparu. + Commencez par ces étapes de dépannage: +

      + +
        +
      1. + Vérifiez la console JavaScript à la recherche d'erreurs, et assurez-vous d'utiliser un callback + `onError` à l'appel de `.load()` pour afficher le résultat. +
        2. +
      2. + Visualisez le modèle dans une autre application. Pour glTF, des visualiseurs de type cliquez-glissez + sont disponibles pour + three.js et + babylon.js. Si le modèle + apparaît correctement dans une ou plusieurs autres applications, + signalez une erreur auprès de three.js. + Si le modèle ne peut être visualisé dans n'importe quelle application, nous encourageons fortement + le signalement d'un bug auprès de l'application avec laquelle vous avez réalisé le modèle 3D. +
        3. +
      3. + Essayez de divisier ou de multiplier la taille du modèle par un facteur de 1000. Plusieurs modèles sont mis à + l'échelles différemment, et les gros modèles peuvent ne pas apparaître si la caméra est + à l'intérieur du modèle. +
        4. +
      4. + Essayez d'ajouter et de positionner une source de lumière. Le modèle peut-être caché dans le noir. +
        5. +
      5. + Cherchez des requêtes concernant des textures erronnées dans votre onglet réseau, comme + `"C:\\Path\To\Model\texture.jpg"`. Utilisez des chemins relatifs menant à votre + modèle à la place, comme `images/texture.jpg` — cela peut nécessiter + la modification du fichier du modèle dans un éditeur de texte. +
        6. +
      + +

      Demander de l'aide

      + +

      + Si vous avez effectué le processus de dépannage ci-dessus et que votre modèle + ne fonctionne toujours pas, utiliser la bonne approche pour demander de l'aide vous mènera + plus rapidement à la solution. Postez une question sur le + forum three.js et, incluez dès que possible, + votre modèle (ou un modèle plus simple avec le même problème) dans n'importe quel format + qui vous est disponible. Incluez sufisamment d'informations pour que quelqu'un puisse reproduire + ce problème rapidement — idéalement, une démo live. +

      + +

      + Three.js utilise des `matrices` pour encoder des transformations 3D---translations (position), rotations, et mise à l'échelle. Chaque instance d'un [page:Object3D] a une [page:Object3D.matrix matrix] qui stocke la position de l'objet, sa rotation, ainsi que son échelle. Cette page décrit comment mettre à jour les transformations d'un objet. +

      + +

      Propriétés de commodité et `matrixAutoUpdate`

      + +

      + Il y a deux façons de mettre à jour les transformations d'un objet: +

      +
        +
      1. + Modifier les propriétés `position`, `quaternion`, et `scale` de l'objet, et laissez three.js recalculer + la matrice de l'objet à l'aide de ces propriétés: + +object.position.copy( start_position ); +object.quaternion.copy( quaternion ); + + Par défaut, la propriété `matrixAutoUpdate` est à true, et la matrice sera automatiquement recalculée. + Si l'objet est statique, ou si vous souhaitez contrôler manuellement quand le recalcul de la matrice intervient, de meilleur performances peuvent-être obtenues en définissant la propriété comme false: + +object.matrixAutoUpdate = false; + + Et après avoir changé n'importe quelle propriété, mettez manuellement la matrice à jour: + +object.updateMatrix(); + +
        2. +
      2. + Modifier la matrice de l'objet directement. La classe [page:Matrix4] dipose de différentes méthodes pour modifier les matrices: + +object.matrix.setRotationFromQuaternion( quaternion ); +object.matrix.setPosition( start_position ); +object.matrixAutoUpdate = false; + + Notez que `matrixAutoUpdate` doit être définie comme `false` dans ce cas, et vous devez vérifier que vous n'appelez pas `updateMatrix`. Appeler `updateMatrix` écrasera les modifications manuelles apportées à la matrice, en recalculant la matrice grâce à sa `position`, `scale`, ainsi de suite. +
        3. +
      + +

      Matrices d'objets et du monde

      +

      + La [page:Object3D.matrix matrix] d'un objet stocke les transformations relatives au [page:Object3D.parent parent] de l'objet; pour obtenir les transformations de l'objets en coordonnées du monde, vous devez accéder à la [page:Object3D.matrixWorld] de l'objet. +

      +

      + Quand les transformations de l'objet parent ou enfant changent, vous pouvez demander que la [page:Object3D.matrixWorld matrixWorld] de l'objet enfant soit mise à jour en appelant [page:Object3D.updateMatrixWorld updateMatrixWorld](). +

      + +

      Rotation et Quaternions

      +

      + Three.js propose deux manières de représenter les rotations 3D: [page:Euler Euler angles] et [page:Quaternion Quaternions], ainsi que des méthodes pour effectuer des conversions entre les deux. Les angles d'Euler sont sujets à un problème nommé "gimbal lock", où certaines configurations peuvent perdre un certain degré de liberté (empêchant l'objet d'effectuer une rotation sur un axe). Pour cette raison, les rotations d'objets sont toujours stockées dans la propriété [page:Object3D.quaternion quaternion] de l'objet. +

      +

      + Des versions précédentes de la librairie incluaient une propriété `useQuaternion` qui, si réglée sur false, faisait que la [page:Object3D.matrix matrix] matrice de l'objet était calculée depuis un angle d'Euler. Cette pratique est dépassée---à la place, vous devez utiliser la méthode [page:Object3D.setRotationFromEuler setRotationFromEuler], qui mettra le quaternion à jour. +

      Testare con NPM ([name])

      + +

      + Questo articolo mostra come inserire three.js in un ambiente + [link:https://nodejs.org/en/ node.js] così che tu possa eseguire test + automatici. I test possono essere eseguiti da linea di comando o da + strumenti CI automatici come [link:https://travis-ci.org/ Travis]. +

      + +

      Versione breve

      + +

      + Se sei a tuo agio con node e npm, installa npm + $ npm install three --save-dev + e aggiungi + const THREE = require('three'); + al tuo test. +

      + +

      Creare un progetto testabile da zero

      +

      + Se non sei familiare con questi strumenti, ecco una guida rapida per + linux (il processo di installazione sarà leggermente diverso usando + Windows, ma i comandi NPM saranno uguali). +

      + +

      Configurazione di base

      +
      +
        +
      1. + Installa [link:https://www.npmjs.org/ npm] e nodejs. Il percorso più + breve in genere assomiglia a qualcosa del simile: + +$ sudo apt-get install -y npm nodejs-legacy +# fix any problems with SSL in the default registry URL +$ npm config set registry http://registry.npmjs.org/ + +
        2. + +
      2. + Crea una nuova cartella per il progetto + $ mkdir test-example; cd test-example +
        3. + +
      3. + Crea un nuovo file di progetto tramite npm: + $ npm init + e accetta tutti i valori suggeriti premendo Enter per ogni richiesta. + Con queste richieste si creerà il file package.json. +
        4. +
        + +
      4. + Prova ad avviare la funzione di test con: + $ npm test + fallirà, come ci aspettiamo. Se controlli nel file package.json la + definizione dello script di test è: + "test": "echo \"Error: no test specified\" && exit 1" +
        5. +
      +
      + +

      Aggiungere mocha

      +
      + Utilizzeremo [link:https://mochajs.org/ mocha]. + +
        +
      1. + Installare mocha con: + $ npm install mocha --save-dev + Si noti che è stata creata la cartella node_modules/ e le tue + dipendenze sono state installate al suo interno. Inoltre, si noti che + il file package.json è stato aggiornato: è stata aggiunta la proprietà + devDependencies, aggiornata dal comando --save-dev. +
        2. +
        + +
      2. + Modificare il file package.json per usare mocha per i test. Quando + viene invocato il test, vogliamo eseguire mocha e specificare un + reporter dettagliato. Per impostazione predefinita questo eseguirà + qualsiasi cosa nella cartella test/ (non avendo una cartella test/ si può + incorrere in un npm ERR!, bisogna crearla con il comando mkdir test) + "test": "mocha --reporter list" +
        3. + +
      3. + Rilanciare il test con: + $ npm test + + Adesso il test dovrebbe essere eseguito con successo, riportando "0 passing (1ms) or + similar". +
        4. +
      +
      + +

      Aggiungere three.js

      +
      +
        +
      1. + Inseriamo la nostra dipendenza three.js con il comando: + $ npm install three --save-dev +
          +
        • + Se hai bisogno di una versione di three.js diversa, usa + $ npm show three versions + per vedere quali sono le versioni disponibili. Per dire ad npm la versione + scelta, usa + $ npm install three@0.84.0 --save + (0.84.0 nell'esempio). --save fa sì che sia una dipendenza del + progetto piuttosto che una devDependecy. Per maggiori informazioni + consulta il documento + [link:https://docs.npmjs.com/cli/v8/configuring-npm/package-json qui]. +
          • +
        +
        2. + +
      2. + Mocha cercherà i test nella cartella test/, quindi creiamola + $ mkdir test +
        3. + +
      3. + Infine abbiamo effettivamente bisogno di un test JS per l'esecuzione. + Aggiungiamo un semplice test il quale verificherà che l'oggetto + three.js sia disponibile e funzionante. Crea il file + test/verify-three.js contenente: + +const THREE = require('three'); +const assert = require('assert'); + +describe('The THREE object', function() { + it('should have a defined BasicShadowMap constant', function() { + assert.notEqual('undefined', THREE.BasicShadowMap); + }), + + it('should be able to construct a Vector3 with default of x=0', function() { + const vec3 = new THREE.Vector3(); + assert.equal(0, vec3.x); + }) +}) + +
        4. + +
      4. + Adesso rieseguiamo il test con il comando $ npm test. Questo dovrebbe + eseguire i test sopra definiti e terminare con successo, mostrando qualcosa del tipo: + +The THREE object should have a defined BasicShadowMap constant: 0ms +The THREE object should be able to construct a Vector3 with default of x=0: 0ms +2 passing (8ms) + +
        5. +
      +
      + +

      Aggiungere il tuo codice

      +
      + Hai bisogno di fare tre cose: + +
        +
      1. + Scrivere un test per il comportamento che di aspetti dal tuo codice, e + metterlo all'interno della cartella test/. + [link:https://github.com/air/encounter/blob/master/test/Physics-test.js Qui] un esempio di un progetto reale. +
        2. + +
      2. + Esportare il tuo codice funzionale in modo tale che nodejs possa vederlo + per usarlo insieme a require. Controlla + [link:https://github.com/air/encounter/blob/master/js/Physics.js qui]. +
        3. + +
      3. + Richiamare il tuo codice nel file di test, allo stesso modo in cui + abbiamo fatto per richiamare three nell'esempio sopra `require('three')` +
        4. +
      + +

      + Il punto 2 e 3 saranno molto dipendenti da come hai gestito il tuo codice. + Nell'esempio di Physics.js fornito sopra, la parte di esportazione si trova giustamente + alla fine. Assegniamo un oggetto a module.exports: +

      + +//============================================================================= +// make available in nodejs +//============================================================================= +if (typeof exports !== 'undefined') { module.exports = Physics; } + +
      + +

      Affrontare le dipendenze

      +
      +

      + Se stai già utilizzando qualcosa di smart come require.js o browserify, + salta questa parte. +

      +

      + Tipicamente un progetto three.js verrà eseguito nel browser. Il caricamento + del modulo viene quindi eseguito dal browser che esegue una serie di tag + di script. I tuo singoli file non si devono preoccupare per le dipendenze. + Tuttavia, in un contesto nodejs non è presente il file index.html che lega tutto + insieme, quindi devi essere esplicito. +

      +

      + Se stai esportando un modulo che dipende da altri file, dovrai dire a node + di caricarli. Di seguito un approccio: +

      +
        +
      1. + All'inizio del tuo modulo, controlla se ti trovi in un ambiente nodejs. +
        2. +
      2. Se è così, dichiara esplicitamente le tue dipendenze.
        3. +
      3. + In caso contrario, probabilmente sei in un browser e quindi non devi fare + nient'altro. +
        4. +
      + Esempio di codice da Physics.js: + +//============================================================================= +// setup for server-side testing +//============================================================================= +if (typeof require === 'function') // test for nodejs environment { + const THREE = require('three'); const MY3 = require('./MY3.js'); } + +

      Sistema di animazione ([name])

      + +

      Panoramica

      + +

      + Con il sistema di animazione di three.js si possono animare varie proprietà dei modelli: + le ossa di un [page:SkinnedMesh modello skinned], i target morph, le diverse proprietà dei materiali + (colori, opacità, booleani), la visibilità e le trasformazioni. Le proprietà di animazione possono essere + sfumate, incrociate e deformate. Il peso e la scala temporale di diverse animazioni simultanee sullo stesso + oggetto o su oggetti diversi possono essere modificate in modo indipendente. È possibile sincronizzare + diverse animazioni sullo stesso oggetto e su oggetti diversi.

      + + Per ottenere tutto questo in un sistema omogeneo, il [link:https://github.com/mrdoob/three.js/issues/6881 sistema di animazione di three.js] + è stato cambiato completamente nel 2015 (attenzione alle informazioni non aggiornate!), ed ora ha un'architettura simile a quella di Unity/Unreal Engine 4. + Questa pagina fornisce una breve panoramica dei componenti principali del sistema e di come lavorano insieme. +

      + +

      Clip di animazione (AnimationClips)

      + +

      + Se si è importato con successo un oggetto 3D animato (non importa se ha ossa o target morph o entrambi) + - per esempio esportandolo da Blender con [link:https://github.com/KhronosGroup/glTF-Blender-IO l'exporter glTF Blender] e caricandolo + nella scena three.js usando [page:GLTFLoader] - uno dei campi di risposta dovrà essere un array chiamato "animations", contenente + gli [page:AnimationClip AnimationClips] per questo modello (vedi l'elenco dei possibili loader qui sotto).

      + + Ogni `AnimationClip` contiene solitamente i dati per una certa attività dell'oggetto. Se la mesh è un personaggio, + per esempio, ci può essere un AnimationClip per la camminata, un altro per il salto e un terzo per il salto laterale e così via. +

      + +

      Keyframe Tracks

      + +

      + All'interno di un `AnimationClip` i dati, per ogni propietà di animazione, sono memorizzati in un [page:KeyframeTrack] separato. + Supponendo che un oggetto personaggio abbia uno [page:Skeleton scheletro], un keyframe track potrebbe memorizzare i dati relativi alle variazioni di + posizione dell'osso inferiore del braccio nel tempo, un'altra traccia potrebbe memorizzare i dati relativi alle variazioni di rotazione dello stesso osso, + una terza traccia la posizione, la rotazione e la scala di un altro osso e così via. Dovrebbe essere chiaro, che un AnimationClip può essere composto + da molte tracce di questo tipo.

      + + Supponendo che il modello abbia dei target morph (per esempio un target morph che mostra una faccia amichevole e un altro che mostra una faccia arrabbiata), + ogni traccia contiene le informazioni su come l'influenza di un certo target morph cambia durante l'esecuzione del clip. +

      + +

      Mixer di Animazioni

      + +

      + I dati memorizzati costituiscono solo la base per le animazioni - la riproduzione vera e propria è controllata dall'[page:AnimationMixer]. + È possibile immaginarlo non solo come un lettore di animazioni, ma come un simulatore di un hardware come una vera e propria console di mixaggio, + che può controllare diverse animazioni simultaneamente, mescolandole e fondendole. +

      + +

      Azioni di Animazioni

      + +

      + Lo stesso `AnimationMixer` ha pochissime proprietà e metodi (generali), perché può essere controllato dall'[page:AnimationAction AnimationActions]. + Per configurare un `AnimationAction` è necessario specificare quando un `AnimationClip` deve essere eseguito, messo in pausa o stoppato su uno dei mixer, + se e con quale frequenza la clip deve essere ripetuta, se deve essere eseguita con una dissolvenza o una scala temporale e altre cose aggiuntive come + dissolvenza incrociata o sincronizzazione. +

      + +

      Gruppi di oggetti Animati

      + +

      + Se si desidera che un gruppo di oggetti riceva uno stato di animazione condiviso, è possibile utilizzare un [page:AnimationObjectGroup]. +

      + +

      Formati supportati e Loader

      + +

      + Si noti che non tutti i formati includono le animazioni (in particolare OBJ non lo fa) e che solo alcuni loader di three.js + supportano le sequenze [page:AnimationClip AnimationClip]. Di seguito alcuni che supportano questo tipo di animazioni: +

      Gestione del colore ([name])

      + +

      Cos'è lo spazio colore?

      + +

      + Ogni spazio colore è una collezione di diverse decisioni progettuali, + scelte insieme per supportare un'ampia gamma di colori e al contempo + soddisfare i vincoli tecnici legati alla precisione e alle tecnologie di + visualizzazione. Quando si crea una risorsa 3D, o si assemblano delle + risorse 3D insieme in una scena, è importante sapere quali sono queste + proprietà e come le proprietà di uno spazio colore si relazionano con + altri spazi colore nella scena. +

      + +
      + +
      + Colori sRGB e il punto di bianco (D65) visualizzati nel diagramma + cromatico di riferimento CIE 1931. La regione colorata rappresenta una + proiezione 2D della gamma sRGB, che è un volume 3D. Fonte: + Wikipedia +
      +
      + +
        +
      • + Colori primari: I colori primari (rosso, verde, blu) non sono + assoluti; vengono selezionati dallo spettro visibile in base ai vincoli + di precisione limitata e alla capacità dei dispositivi di + visualizzazione disponibili. I colori sono espressi come rapporto tra i + colori primari. +
        • +
      • + Punto di bianco: La maggior parte degli spazi colore è progettata + in modo tale che una somma equamente ponderata di primari + R = G = B appaia priva di colore o "acromatica". L'aspetto dei + valori cromatici (come il bianco o il grigio) dipende dalla percezione + umana, che a sua volta dipende fortemente dal contesto dell'osservatore. + Uno spazio colore specifica il suo "punto di bianco" per bilanciare + queste esigenze. Il punto di bianco definito dallo spazio colore sRGB è + D65. +
        • +
      • + Funzioni di trasferimento (transfer functions): Dopo aver scelto + la gamma cromatica e un modello di colore, dobbiamo ancora definire le + mappature ("funzioni di trasferimento") dei valori numerici da/verso lo + spazio colore. R = 0,5 rappresenta il 50% in meno di illuminazione + fisica rispetto a r = 1,0? O il 50% in meno di luminosità, come + percepito da un occhio umano medio? Sono cose diverse e questa + differenza può essere rappresentata come una funzione matematica. Le + funzioni di trasferimento possono essere lineari o + non lineari, a seconda degli obiettivi dello spazio colore. sRGB + definisce funzioni di trasferimento non lineari. Queste funzioni sono + talvolta approssimate come funzioni gamma, ma il termine "gamma" + è ambiguo e dovrebbe essere evitato in questo contesto. +
        • +
      + + Questi tre parametri - colori primari, punto di bianco e funzioni di + trasferimento - definiscono uno spazio colore, ognuno scelto per obiettivi + specifici. Dopo aver definito i parametri, sono utili alcuni termini + aggiuntivi: + +
        +
      • + Modello di colore: Sintassi per identificare numericamente i + colori all'interno della gamma cromatica scelta - un sistema di + coordinate per i colori. In three.js ci occupiamo principalmente del + modello di colore RGB, con tre coordinate + r, g, b ∈ [0,1] ("dominio chiuso") o + r, g, b ∈ [0,∞] ("dominio aperto") che rappresentano ciascuna una + frazione di un colore primario. Altri modelli di colore (HSL, Lab, LCH) + sono comunemente utilizzati per il controllo artistico. +
        • +
      • + Gamma di colori: Quando i colori primari e il punto di bianco + sono stati scelti, questi rappresentano un volume all'interno dello + spettro visibile (un "gamut"). I colori che non rientrano in questo + volume ("fuori gamut") non possono essere espressi dai valori RGB del + dominio chiuso [0,1]. Nel dominio aperto [0,∞], il gamut è tecnicamente + infinito. +
        • +
      + +

      + Consideriamo due spazi colori comuni: [page:SRGBColorSpace] ("sRGB") e + [page:LinearSRGBColorSpace] ("Linear-sRGB"). Entrambi usano gli stessi + colori primari e lo stesso punto di bianco, e quindi hanno la stessa gamma + di colori. Entrambi utilizzano il modello di colore RGB. Sono diversi solo + nelle funzioni di trasferimento - Linear-sRGB è lineare rispetto + all'intensità della luce fisica, mentre sRGB utilizza le funzioni di + trasferimento non lineari di sRGB e si avvicina maggiormente al modo in + cui l'occhio umano percepisce la luce e alla reattività dei comuni + dispositivi di visualizzazione. +

      + +

      + Questa differenza è importante. I calcoli di illuminazione e altre + operazioni di rendering devono generalmente avvenire in uno spazio di + colore lineare. Tuttavia, i colori lineari sono meno efficienti da + memorizzare in un'immagine o in un framebuffer e non hanno un aspetto + corretto quando vengono osservati da un osservatore umano. Di conseguenza, + le texture di input e l'immagine finale renderizzata utilizzano + generalmente lo spazio di colore sRGB non lineare. +

      + +
      +

      + ℹ️ + ATTENZIONE: Anche se alcuni display moderni supportano gamme + più ampie come Display-P3, le API grafiche della piattaforma web si + basano in gran parte su sRGB. Le applicazioni che utilizzano three.js + oggi utilizzano in genere solo gli spazi colore sRGB e Linear-sRGB. + +

      +
      + +

      Ruoli degli spazi colore

      + +

      + Un flusso di lavoro lineare - richiesto per moderni metodi di rendering - + generalmente coinvolge più di uno spazio di colore, ognuno assegnato ad un + ruolo specifico. Spazi colore lineari o non lineari sono adatti a ruoli + diversi, come spiegato di seguito. +

      + +

      Input color space

      + +

      + I colori forniti a three.js - dai color picker, dalle texture, dai modelli + 3D e da altre risorse - hanno ciascuno uno spazio colore associato. Quelli + che non sono già nello spazio colore di lavoro Linear-sRGB devono essere + convertiti e alle texture deve essere assegnata la corretta assegnazione + texture.encoding. Alcune conversioni (per i colori esadecimali e + CSS in sRGB) possono essere effettuate automaticamente se la modalità di + gestione del colore legacy è disabilitata prima dell'inizializzazione dei + colori: +

      + + THREE.ColorManagement.legacyMode = false; + +
        +
      • + Materiali, luci, e shader: I colori nei materiali, nelle luci e + negli shader memorizzano i componenti RGB nello spazio colore di lavoro + Linear-sRGB. +
        • +
      • + Colori dei vertici: [page:BufferAttribute BufferAttributes] + memorizza i componenti RGB nello spazio colore di lavoro Linear-sRGB. +
        • + +
      • + Colori delle texture: Le [page:Texture Texture] PNG o JPEG + contenti informazioni sul colore (come .map o .emissiveMap) usano lo + spazio colore sRGB a dominio chiuso, e devono essere annotate con + texture.encoding = sRGBEncoding. I formati come OpenEXR (a volte + usati per .envMap o .lightMap) utilizzano lo spazio colore Linear-sRGB + indicato con texture.encoding = LinearEncoding, e possono + contenere valori nel dominio aperto [0,∞]. +
        • +
      • + Texture non a colori: Le texture che non memorizzano informazioni + relative ai colori (come .normalMap o .roughnessMap) non hanno associato + uno spazio colore, e generalmente usano l'annotazione (predefinita) + texture.encoding = LinearEncoding. In rari casi, i dati non a + colori possono essere rappresentati con altre codifiche non lineari per + motivi tecnici. +
        • +
      + +
      +

      + ⚠️ + ATTENZIONE: Molti formati per modelli 3D non definiscono + correttamente o in modo coerente le informazioni sullo spazio colore. + Sebbene three.js tenti di gestire la maggior parte dei casi, i + problemi sono spesso con i file con formati meno recenti. Per ottenere + un miglior risultato bisogna utilizzare il formato glTF 2.0 + ([page:GLTFLoader]) e prima bisogna testare i modelli 3D in + visualizzatori online per confermare che la risorsa stessa sia + corretta. + +

      +
      + +

      Spazio colore di lavoro

      + +

      + Rendering, interpolazione e molte altre operazioni devono essere eseguite + in uno spazio colore di lavoro lineare, nel quale i componenti RGB sono + proporzionali all'illuminazione fisica. In three.js, lo spazio colore di + lavoro è Linear-sRGB. +

      + +

      Output color space

      + +

      + L'output su un dispositivo di visualizzazione, a un'immagine o a un video, + può comportare la conversione dallo spazio colore di lavoro Linear-sRGB di + dominio aperto a un altro spazio di colore. Questa conversione può essere + eseguita nel passaggio di rendering principale + ([page:WebGLRenderer.outputEncoding]), o durante il post-processing. +

      + + + renderer.outputEncoding = THREE.sRGBEncoding; // optional with post-processing + + +
        +
      • + Display: I colori scritti in un canvas WebGL per i display devono + essere nello spazio colore sRGB. +
        • +
      • + Immagine: I colori scritti su un'immagine devono utilizzare lo + spazio colore appropriato per il formato e per il suo uso. Le immagini + completamente renderizzate scritte per texture PNG o JPEG generalmente + usano lo spazio colore sRGB. Immagini contenenti emissioni, mappe di + luce, o altri dati non limitati all'intervallo [0,1] utilizzaranno + generalmente lo spazio colore Linear-sRGB a dominio aperto, e un formato + immagine compatibile come OpenEXR. +
        • +
      + +
      +

      + ⚠️ + ATTENZIONE: I target di rendering possono utilizzare sia sRGB + che Linear-sRGB. sRGB utilizza meglio la precisione limitata. Nel + dominio chiuso, 8 bit sono sufficienti per sRGB mentre ≥12 (mezzo + float) possono essere richiesti per Linear-sRGB. Se gli stadi + successivi delle pipeline richiedono un ingresso Linear-sRGB, le + conversioni aggiuntive possono avere un piccolo costo in termini di + prestazioni. +

      +
      + +

      Lavorare con le istanze di THREE.Color

      + +

      + I metodi di lettura o modifica delle istanze [page:Color] presuppongono + che i dati siano già nello spazio colore di lavoro di three.js, + Linear-sRGB. I componenti RGB e HSL sono rappresentazioni dirette dei dati + memorizzati dall'istanza Color, e non sono mai convertiti implicitamente. + I dati di Color possono essere esplicitamenre convertiti con + .convertLinearToSRGB() o .convertSRGBToLinear(). +

      + + + // RGB components (no change). + color.r = color.g = color.b = 0.5; + console.log( color.r ); // → 0.5 + + // Manual conversion. + color.r = 0.5; + color.convertSRGBToLinear(); + console.log( color.r ); // → 0.214041140 + + +

      + Con ColorManagement.legacyMode = false impostato (consigliato), + alcune conversioni vengono effettuate automaticamente. Poiché i colori + esadecimali e CSS sono generalmente sRGB, i metodi [page:Color] + convertiranno automaticamente questi input da sRGB a Linear-sRGB nei + setter, oppure convertiranno da Linear-sRGB a sRGB quando restituiscono + output esadecimali o CSS dai getter. +

      + + + // Hexadecimal conversion. + color.setHex( 0x808080 ); + console.log( color.r ); // → 0.214041140 + console.log( color.getHex() ); // → 0x808080 + + // CSS conversion. + color.setStyle( 'rgb( 0.5, 0.5, 0.5 )' ); + console.log( color.r ); // → 0.214041140 + + // Override conversion with 'colorSpace' argument. + color.setHex( 0x808080, LinearSRGBColorSpace ); + console.log( color.r ); // → 0.5 + console.log( color.getHex( LinearSRGBColorSpace ) ); // → 0x808080 + console.log( color.getHex( SRGBColorSpace ) ); // → 0xBCBCBC + + +

      Errori comuni

      + +

      + Quando un singolo colore o una texture non sono configurati correttamente, + apparirà più scuro o più chiaro del previsto. Quando lo spazio colore di + output del renderer non è configurato correttamente, l'intera scena + potrebbe essere più scura (ad es. manca la conversione ad sRGB) o più + chiara (ad es. una doppia conversione a sRGB con post-processing). In ogni + caso il problema potrebbe non essere uniforme e semplicemente + aumentare/dimunire la luminosità non lo risolverebbe. +

      + +

      + Un problema più sottile si verifica quando entrambi lo spazio colore di + input e quello di output non sono corretti - i livelli di luminosità complessivi + potrebbero andare bene, ma i colori potrebbero cambiare in modo imprevisto in + condizioni di illuminazione diversa o l'ombreggiatura potrebbe apparire più sbiadita + e meno morbida del previsto. Questi due errori non fanno una cosa giusta, ed è importante + che lo spazio colore di lavoro sia lineare ("riferito alla scena") e che lo spazio di colore + dell'output sia non lineare ("riferito alla visualizzazione"). +

      Creare una scena ([name])

      + +

      Lo scopo di questa sezione è quello di fornire una breve introduzione di three.js. + Inizieremo impostando una scena con un cubo rotante. + Se sei bloccato e hai bisogno di aiuto, in fondo alla pagina troverai un esempio funzionante.

      + +

      Prima di iniziare

      + +

      Prima di poter utilizzare three.js hai bisogno di un posto dove visualizzarlo. + Salva il seguente codice HTML in un file sul tuo computer insieme ad una copia + di [link:https://threejs.org/build/three.js three.js] nella cartella js/, e aprilo nel browser.

      + + + <!DOCTYPE html> + <html> + <head> + <meta charset="utf-8"> + <title>My first three.js app</title> + <style> + body { margin: 0; } + </style> + </head> + <body> + <script src="js/three.js"></script> + <script> + // Il nostro Javascript andrà qui + </script> + </body> + </html> + + +

      Questo è quanto. Tutto il codice seguente va nel tag vuoto <script>.

      + +

      Creare la scena

      + +

      Per poter visualizzare qualsiasi cosa con three.js abbiamo bisogno di tre cose: scena, + telecamera e renderer, in modo da poter renderizzare la scena con la telecamera.

      + + + const scene = new THREE.Scene(); + const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 ); + + const renderer = new THREE.WebGLRenderer(); + renderer.setSize( window.innerWidth, window.innerHeight ); + document.body.appendChild( renderer.domElement ); + + +

      Spieghiamo un attimo cosa sta succedendo. Abbiamo impostato la scena, la telecamera e il renderer.

      + +

      Esistono diverse telecamere in three.js. Per ora usiamo una `PerspectiveCamera`.

      + +

      Il primo attributo è il `field of view` (campo visivo). Il FOV è l'estensione della scena che + viene vista sul display in qualsiasi momento. Il valore è espresso in gradi.

      + +

      Il secondo attributo è l'`aspect ratio` (rapporto di aspetto). + È quasi sempre consigliabile usare la larghezza dell'elemento divisa per l'altezza, + altrimenti si otterrà lo stesso risultato di quando si riproducono vecchi film su un televisore widescreen - l'immagine appare schiacciata.

      + +

      I successivi due attributi sono il piano di ritaglio, `near` (il vicino) e `far` (il lontano). + Ciò significa che gli oggetti più lontani dalla telecamera rispetto al valore `far` o più vicini + rispetto al valore `near` non saranno renderizzati. Non è neccessario preoccuparsi di questo + aspetto adesso, ma potresti voler usare altri valori nella tua applicazione per avere delle prestazioni migliori.

      + +

      Il prossimo passo è il renderer. È qui che avviene la magia. Oltre al WebGLRenderer che usiamo qui, + three.js fornisce altri renderer, spesso usati come alternativa per utenti che usano browser più vecchi + o per quelli che, per qualche motivo, non hanno il supporto WebGL.

      + +

      Oltre a creare l'istanza del renderer, abbiamo bisogno di impostare le dimensioni con cui vogliamo che l'applicazione venga visualizzata. È una buona idea usare la larghezza e l'altezza dell'area che vogliamo riempire con la nostra applicazione - in questo caso, la larghezza e l'altezza della finestra del browser. Per le applicazioni ad alte prestazioni si possono dare a `setSize` dei valori più piccoli, come `window.innerWidth/2` e `window.innerHeight/2`, che faranno si che l'applicazione venga renderizzata ad una dimensione di un quarto.

      + +

      Se si desidera mantenere la dimensione dell'applicazione ma visualizzarla ad una risoluzione minore, è possibile farlo aggiungendo a `setSize` il valore false, corrispondente a `updateStyle` (il terzo parametro). Per esempio, `setSize(window.innerWidth/2, window.innerHeight/2, false)` visualizzerà l'applicazione a metà risoluzione, dato che il <canvas> ha larghezza e altezza del 100%.

      + +

      Infine, aggiungiamo l'elemento `renderer` al nostro documento HTML. Si tratta di un elemento <canvas> che il renderer utilizza per visualizzare la scena.

      + +

      "Va bene, ma dov'è il cubo che ci avevi promesso?" Aggiungiamolo ora.

      + + + const geometry = new THREE.BoxGeometry( 1, 1, 1 ); + const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } ); + const cube = new THREE.Mesh( geometry, material ); + scene.add( cube ); + + camera.position.z = 5; + + +

      Per creare un cubo abbiamo bisogno di una `BoxGeometry`. Un oggetto che contiene tutti i punti (`vertices`) e le facce (`faces`) del cubo. Lo esploreremo meglio in futuro.

      + +

      Oltre alla geometria, abbiamo bisogno di un materiale per colorarla. Three.js mette a disposizione molti materiali, ma per ora ci limiteremo al `MeshBasicMaterial`. Tutti i materiali come parametro accettano un oggetto al cui interno avrà delle proprietà che li verrano applicate. Per mantenere le cose molto semplici, impostiamo solo un attributo di colore verde `0x00ff00`. Questo funziona come i colori nei CSS o in Photoshop (`hex colors`).

      + +

      La terza cosa di cui abbiamo bisogno è una `Mesh`. Una mesh è un oggetto che prende una geometria, e le applica un materiale, che possiamo, poi, inserire nella scena e spostare liberamente.

      + +

      Per impostazione predefinita, quando chiamiamo `scene.add()`, la cosa che sarà aggiunta verrà posizionata nelle coordinate `(0,0,0)`. In questo modo la telecamera e il cubo si troveranno l'uno dentro l'altro. Per evitare questo inconveniente, è sufficiente spostare la telecamera un po' più in là.

      + +

      Renderizzare la scena

      + +

      Se si copiasse il codice qui sopra nel file HTML creato in precedenza, non si vedrebbe nulla. Questo perché ancora non stiamo visualizzando nulla. Per questo abbiamo bisogno di quello che viene chiamato un ciclo `render o animate`.

      + + + function animate() { + requestAnimationFrame( animate ); + renderer.render( scene, camera ); + } + animate(); + + +

      Questa funzione creerà un loop che fa sì che il renderer disegni la scena ogni volta che la scena viene aggiornata + (su uno schermo tipico questo vuol dire 60 volte al secondo). Se sei nuovo nella scrittura di giochi su browser, + potresti dire "perché non creiamo semplicemente un setInterval?" Il fatto è che potremmo ma `requestAnimationFrame` + ha una serie di vantaggi. Forse il più importante è che si interrompe quando l'utente passa ad un'altra scheda del browser, + così da non sprecare la preziosa potenza di elaborazione e la vita della batteria del computer.

      + +

      Animare il cubo

      + +

      Se inserisci tutto il codice sopra nel file che hai creato prima di iniziare, dovresti vedere un box verde. + Rendiamo tutto un po' più interessante ruotandolo.

      + +

      Aggiungi quanto segue proprio sopra la chiamata `renderer.render` nella tua funzione `animate`:

      + + + cube.rotation.x += 0.01; + cube.rotation.y += 0.01; + + +

      Verrà eseguito per ogni frame (normalmente 60 volte per secondo) e darà al cubo un'animazione di rotazione. + Fondamentalmente, tutto ciò che vuoi spostare o modificare mentre l'applicazione è in esecuzione deve passare + attraverso il ciclo di animazione. Ovviamente, si possono chiamare altre funzioni all'interno di `animate`, + in modo da non avere una funzione con centinaia di righe.

      + +

      Il risultato

      +

      Congratulazioni! Hai completato la tua prima applicazione three.js. È semplice, ma da qualche parte devi pur iniziare.

      Creare testo ([name])

      +
      +

      + Spesso si ha la necessità di utilizzare del testo nella propria applicazione three.js - ecco un paio di modi per farlo. +

      +
      + +

      1. DOM + CSS

      +
      +

      + L'uso dell'HTML è generalmente il modo più facile e veloce per aggiungere testo. Questo è il metodo + usato per gli overlay descrittivi in quasi tutti gli esempi di three.js. +

      +

      È possibile aggiungere contenuto ad un div:

      + <div id="info">Description</div> + +

      + e usare il markup CSS per posizionare l'elemento in modo assoluto, in una posizione sopra tutti gli altri elementi + con la proprietà z-index, specialmente se three.js viene eseguito in modalità full screen. +

      + + +#info { + position: absolute; + top: 10px; + width: 100%; + text-align: center; + z-index: 100; + display:block; +} + + +
      + + +

      2. Usare [page:CSS2DRenderer] o [page:CSS3DRenderer]

      +
      +

      + Questi renderer vengono utilizzati per disegnare testo di alta qualità all'interno di elementi del DOM nella scena three.js. + Questo metodo è simile al punto 1 eccetto per il fatto che con questi renderer è possibile integrare più facilmente e dinamicamente gli elementi nella scena three.js. +

      +
      + + +

      3. Disegnare il testo nel canvas e usarlo come [page:Texture]

      +
      +

      Utilizza questo metodo se desideri disegnare testo facilmente su un piano nella scena three.js.

      +
      + + +

      4. Disegnare un modello nella tua applicazione 3D preferita ed esportarlo in three.js

      +
      +

      Utilizza questo metodo se preferisci lavorare con la tua applicazione 3D e importare i modelli in three.js.

      +
      + + +

      5. Text Geometry Procedurale

      +
      +

      + Se preferisci lavorare solo in three.js o creare geometrie di testo 3D dinamiche e procedurali, è possibile creare una mesh che abbia come geometria + un'istanza di THREE.TextGeometry: +

      +

      + new THREE.TextGeometry( text, parameters ); +

      +

      + In modo tale che questo funzioni correttamente, TextGeometry necessita che un'istanza di THREE.Font venga impostata come valore del parametro "font". + Per avere maggiori informazioni su come implementare questo metodo, consulta la pagina [page:TextGeometry], contenente la descrizione di ogni + parametro che la classe accetta e una lista di font JSON che vengono forniti con la distribuzione di three.js. +

      + +

      Disegnare linee ([name])

      +
      +

      + Diciamo che tu voglia disegnare una linea o un cerchio, non un wireframe [page:Mesh]. + Prima bisogna impostare il [page:WebGLRenderer renderer], la [page:Scene scene] e la camera (vedi la pagina Creare una scena). +

      + +

      Di seguito il codice che utilizzeremo:

      + +const renderer = new THREE.WebGLRenderer(); +renderer.setSize( window.innerWidth, window.innerHeight ); +document.body.appendChild( renderer.domElement ); + +const camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 500 ); +camera.position.set( 0, 0, 100 ); +camera.lookAt( 0, 0, 0 ); + +const scene = new THREE.Scene(); + +

      La prossima cosa da fare è definire il materiale. Per le linee possiamo usare [page:LineBasicMaterial] o [page:LineDashedMaterial].

      + +//crea una LineBasicMaterial blu +const material = new THREE.LineBasicMaterial( { color: 0x0000ff } ); + + +

      + Dopo la definizione del materiale abbiamo bisogno di una geometria con alcuni vertici: +

      + + +const points = []; +points.push( new THREE.Vector3( - 10, 0, 0 ) ); +points.push( new THREE.Vector3( 0, 10, 0 ) ); +points.push( new THREE.Vector3( 10, 0, 0 ) ); + +const geometry = new THREE.BufferGeometry().setFromPoints( points ); + + +

      Da notare che le linee vengono tracciate tra ogni coppia consecutiva di vertici, ma non tra il primo e l'ultimo vertice (la linea non è chiusa).

      + +

      Ora che abbiamo i punti per due linee e un materiale, possiamo unirli per formare una linea.

      + +const line = new THREE.Line( geometry, material ); + +

      Non resta che aggiungerlo alla scena e chiamare il [page:WebGLRenderer.render render].

      + + +scene.add( line ); +renderer.render( scene, camera ); + + +

      Ora dovresti vedere una freccia che punta verso l'alto formata da due linee blu.

      FAQ ([name])

      + +

      Qual è il formato per i modelli 3D meglio supportato?

      +
      +

      + Il formato raccomandato per importare ed esportare modelli 3D è il glTF (GL Transmission Format). + Poiché è focalizzato sulla distribuzione di risorse in runtime, è compatto da trasmettere e veloce da caricare. +

      +

      + Three.js mette a disposizione loader per molti altri formati popolari come FBX, Collada o OBJ. + Tuttavia, si dovrebbe, nei propri progetti, sempre cercare di stabilire prima un flusso di lavoro basato su glTF. + Per maggiori informazioni consultare la guida sul [link:#manual/introduction/Loading-3D-models caricamento dei modelli 3D]. +

      +
      + +

      Perché negli esempi sono presenti meta tag viewport?

      +
      + <meta name="viewport" content="width=device-width, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0"> + +

      Questi tag controllano le dimensioni e la scala del viewport per i browser su mobile (dove il contenuto della pagina può essere visualizzato con dimensioni diverse rispetto al viewport).

      +
      + +

      Come si può conservare la scala della scena durante il ridimensionamento?

      +

      + Vogliamo che tutti gli oggetti indipendentemente dalla loro distanza dalla camera, siano visualizzati con le stesse dimensioni anche se la finestra viene ridimensionata. + + L'equazione chiave per risolvere questo problema è data da questa formula per l'altezza visibile ad una data distanza: + + +visible_height = 2 * Math.tan( ( Math.PI / 180 ) * camera.fov / 2 ) * distance_from_camera; + + Se aumentiamo l'altezza della finestra di una certa percentuale, vogliamo che l'altezza visibile a tutte le distanze aumenti della stessa percentuale. + + Questo non può essere fatto cambiando la posizione della camera. È invece necessario modificare il valore del campo visivo (fov) della camera. + [link:http://jsfiddle.net/Q4Jpu/ Esempio]. +

      + +

      Perché una parte del mio oggetto è invisibile?

      +

      + Questo comportamento può essere causato dal "face culling" (eliminazione delle facce). Le facce hanno un orientamento che decide quale lato è quello giusto. + E il culling (eliminazione) rimuove il lato posteriore in circostanze normali. Per verificare se il problema è questo cambia la proprietà side del materiale con THREE.DoubleSide. + + material.side = THREE.DoubleSide +

      + +

      Perché three.js a volte restituisce strani risultati per input non validi?

      +

      + Per ragioni di performance three.js nella maggior parte dei casi non convalida gli input. È responsabilità della tua applicazione di controllare i dati che vengono passati a three.js. +

      Come creare contenuti VR ([name])

      + +

      + Questa guida fornisce una breve panoramica sui componenti di base di un'applicazione VR basata sul web realizzata con three.js. +

      + +

      Workflow

      + +

      + Prima di tutto devi includere [link:https://github.com/mrdoob/three.js/blob/master/examples/jsm/webxr/VRButton.js VRButton.js] nel tuo progetto. +

      + + +import { VRButton } from 'three/addons/webxr/VRButton.js'; + + +

      + *VRButton.createButton()* fa due cose importanti: Crea un bottone per indicare la compatibilità con il VR. + Inoltre, se l'utente attiva il bottone, viene avviata una sessione VR. L'unica cosa che devi fare è aggiungere la seguente + linea di codice al tuo progetto. +

      + + +document.body.appendChild( VRButton.createButton( renderer ) ); + + +

      + Successivamente, hai bisogno di dire alla tua istanza di `WebGLRenderer` di abilitare il rendering XR. +

      + + +renderer.xr.enabled = true; + + +

      + Infine, devi regolare il ciclo di animazione poiché non possiamo utilizzare la nota funzione *window.requestAnimationFrame()*. + Per i progetti VR viene utilizzato il metodo [page:WebGLRenderer.setAnimationLoop setAnimationLoop]. + Il codice minimo si presenta così: +

      + + +renderer.setAnimationLoop( function () { + + renderer.render( scene, camera ); + +} ); + + +

      Come liberare le risorse ([name])

      + +

      + Un aspetto importante per migliorare le prestazioni ed evitare perdite di memoria nella tua applicazione è l'eliminazione delle entità della libreria non utilizzate. + Ogni volta che viene creata un'istanza di un tipo *three.js*, viene allocata una certa quantità di memoria. Tuttavia, *three.js* crea per oggetti specifici + come le geometrie o i materiali, entità correlate WebGL, come buffer o programmi shader, necessari per il rendering. È importante sottolineare che + questi oggetti non vengono rilasciati automaticamente. Invece, l'applicazione utilizza una speciale API per liberare tali risorse. Questa guida fornisce + una breve panoramica su come l'API viene utilizzata e quali oggetti sono rilevanti in questo contesto. +

      + +

      Geometrie

      + +

      + Una geometria solitamente rappresenta le informazioni sui vertici come una collezione di attributi. *three.js* internamente crea un oggetto di tipo [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLBuffer WebGLBuffer] + per ogni attributo. Queste entità vengono cancellate solo se viene chiamato il metodo [page:BufferGeometry.dispose](). Se una geometria, nella tua applicazione, + diventa obsoleta, esegui questo metodo per liberare tutte le risorse correlate. +

      + +

      Materiali

      + +

      + Un materiale definisce come sono visualizzati gli oggetti. *three.js* utilizza le informazioni di una definizione di materiale per costruire un programma shader per il rendering. + I programmi shader possono essere cancellati solo se il respettivo materiale è eliminato. Per ragioni di prestazioni, *three.js* prova, se possibile, a riutilizzare + il programma shader già esiste. Quindi un progamma di shader può essere cancellato solo se tutti i relativi materiali sono eliminati. Puoi eseguire l'eliminazione + di un materiale eseguendo il metodo [page:Material.dispose](). +

      + +

      Texture

      + +

      + L'eliminazione di un materiale non ha effetti sulle texture. Queste vengono gestite separatamente, poiché una singola texture può essere usata da più materiali contemporaneamente. + Ogni volta che crei un'istanza di [page:Texture], three.js internamente crea un'istanza di [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLTexture WebGLTexture]. + Come per i buffer, questo oggetto può essere eliminato solo chiamando il metodo[page:Texture.dispose](). +

      + +

      + Se stai usando `ImageBitmap` come origine dati della texture, devi chiamare il metodo [link:https://developer.mozilla.org/en-US/docs/Web/API/ImageBitmap/close ImageBitmap.close]() a livello applicativo per liberare le risorse lato CPU. + Una chiamata automatica di `ImageBitmap.close()`in [page:Texture.dispose]() non è possibile, poiché il bitmap dell'immagine diventa inutilizzabile, e l'engine non ha modo di sapere se il bitmap dell'immagine è utilizzata da altre parti. +

      + +

      Render Target

      + +

      + Oggetti di tipo [page:WebGLRenderTarget] non allocano solo un'istanza di [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLTexture WebGLTexture] ma anche + di [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLFramebuffer WebGLFramebuffer] e di [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderbuffer WebGLRenderbuffer] + per realizzare destinazioni di rendering personalizzate. Questi oggetti vengono solo deallocati eseguendo il metodo [page:WebGLRenderTarget.dispose](). +

      + +

      Varie

      + +

      + Ci sono altre classi nella cartella degli esempi come i control o passaggi di post-processing che forniscono metodi `dispose()` per rimuovere i listener di eventi interni o + renderizzare i target. In generale, viene raccomandato di controllare le API o la documentazione della classe e controllare il metodo `dispose()`. Se presente dovresti utilizzarlo per liberare le risorse. +

      + +

      FAQ

      + +

      Perché *three.js* non può eliminare gli oggetti automaticamente?

      + +

      + Questa domanda è stata fatta spesso dalla community, quindi è importante chiarire la questione. Il fatto è che *three.js* non conosce il ciclo di vita o lo scopo + delle entità create dall'utente come le geometrie o i materiali, questa è una responsabilità dell'applicazione. Per esempio, anche se un materiale non è momentamenente utilizzato per il + rendering, potrebbe essere necessario per il prossimo frame. Quindi se l'applicazione decide che un determianto oggetto può essere cancellato lo notifica all'engine tramite la chiamata + al rispettivo metodo `dispose()`. +

      + +

      La rimozione di una mesh dalla scena elimina anche la sua geometria e il suo materiale?

      + +

      + No, devi eliminare esplicitamente la geometria e il materiale chiamando il metodo *dispose()*. Tieni a mente che le geometrie e i materiali possono essere condivisi tra oggetti 3D come le mesh. +

      + +

      *three.js* fornisce informazioni sulla quantità di oggetti memorizzati nella cache?

      + +

      + Si, è possibile consultare [page:WebGLRenderer.info]. Una proprietà speciale del renderer con una serie di informazioni statistiche sulla memoria della scheda grafica + e il processo di rendering. Tra le altre cose, riporta anche quante texture, geometrie e programmi shader sono internamente memorizzati. Se noti che ci sono problemi + di performance nell'applicazione, è una buona idea debuggare questa proprietà per identificare facilmente se c'è una perdita di memoria. +

      + +

      Che cosa succede quando il metodo `dispose()` viene chiamato su una texture ma l'immagine non è ancora stata caricata?

      + +

      + Le risorse interne di una texture vengono allocate solo se l'immagine è caricata con successo. Se elimini una texture prima che l'immagine venga caricata + non succede niente. Nessuna risorsa è stata allocata, quindi niente deve essere pulito. +

      + +

      Cosa succede quando chiamo `dispose()` e poi utilizzo il rispettivo oggetto in un secondo momento?

      + +

      + Le risorse interne che sono state cancellate saranno ricreate dall'engine, in questo modo non ci saranno errori a runtime. Probabilmente, però, noterai un impatto negativo sulle performance nel + frame corrente quando il programma shader sarà compilato. +

      + +

      Come devo gestire gli oggetti *three.js* nella mia app? Quando so che devo eliminare le risorse?

      + +

      + In generale non c'è una raccomandazione definitiva per questo. Dipende molto dal caso d'uso specifico. È importante sottolineare che non è sempre necessario + eliminare oggetti tutto il tempo. Un buon esempio esemplificativo è un gioco a più livelli. Un buon momento per eliminare gli oggetti è quando viene cambiato il livello. + L'applicazione può attraversare tutta la vecchia scena (livello) ed eliminare tutti i vecchi materiali, geometrie e texture. Come accennato nella sezione precedente, + se viene cancellato un oggetto che è attualmente in uso non produce un errore a runtime. La cosa peggiore che può accadere è un calo delle prestazioni in un singolo frame. +

      + +const object = new THREE.Object3D(); +scene.add( object ); + + o se sono figli di un altro oggetto che è stato aggiunto alla scena: + +const object1 = new THREE.Object3D(); +const object2 = new THREE.Object3D(); + +object1.add( object2 ); +scene.add( object1 ); // object1 e object2 aggiorneranno automaticamente le loro matrici + +
      + +

      Comunque, se sai che l'oggetto sarà statico, puoi disabilitare questo automatismo e aggiornare manualmente la matrice di trasformazione, solo quando necessario.

      + + +object.matrixAutoUpdate = false; +object.updateMatrix(); + + +

      BufferGeometry

      +
      +

      + Le BufferGeometry memorizzano le informazioni (come le posizioni dei vertici, gli indici delle facce, le normali, i colori, + le coordinate UV, e qualsiasi attributo personalizzato) nel [page:BufferAttribute buffer] - cioè in + [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays array tipizzati]. + Ciò le rende generalmente più veloci delle Geometry standard, al costo di essere un po' più difficili da lavorare. +

      +

      + Per quanto riguarda l'aggiornamento delle BufferGeometry, la cosa più importante da capire è che + il buffer non può essere ridimensionato (questo è molto costoso e basicamente equivalente a creare una nuova geometria). + Indipendetemente da questo il contenuto dei buffer può essere comunque aggiornato. +

      +

      + Questo significa che se sai che un attributo della BufferGeometry crescerà, ad esempio il numero di vertici, + è necessario preallocare un buffer sufficientemente grande per contenere i nuovi vertici che potrebbero essere creati. + Ovviamente, questo significa anche che ci sarà una dimensione massima per la tua BufferGeometry - non è possibile + creare una BufferGeometry che possa essere estesa in modo efficiente indefinitamente. +

      +

      + Useremo l'esempio di una linea che viene estesa al momento del rendering. Allocheremo spazio nel buffer per contenere 500 vertici + ma all'inizio ne disegneremo soltanto due, usando [page:BufferGeometry.drawRange]. +

      + +const MAX_POINTS = 500; + +// geometry +const geometry = new THREE.BufferGeometry(); + +// attributes +const positions = new Float32Array( MAX_POINTS * 3 ); // 3 vertices per point +geometry.setAttribute( 'position', new THREE.BufferAttribute( positions, 3 ) ); + +// draw range +const drawCount = 2; // draw the first 2 points, only +geometry.setDrawRange( 0, drawCount ); + +// material +const material = new THREE.LineBasicMaterial( { color: 0xff0000 } ); + +// line +const line = new THREE.Line( geometry, material ); +scene.add( line ); + +

      + Quindi, aggiungeremo punti alla linea in maniera random usando un pattern come questo: +

      + +const positions = line.geometry.attributes.position.array; + +let x, y, z, index; +x = y = z = index = 0; + +for ( let i = 0, l = MAX_POINTS; i < l; i ++ ) { + + positions[ index ++ ] = x; + positions[ index ++ ] = y; + positions[ index ++ ] = z; + + x += ( Math.random() - 0.5 ) * 30; + y += ( Math.random() - 0.5 ) * 30; + z += ( Math.random() - 0.5 ) * 30; + +} + +

      + Se vuoi cambiare il numero di punti visualizzati dopo il primo render, procedi come segue; +

      + +line.geometry.setDrawRange( 0, newValue ); + +

      + Se vuoi cambiare i valori dei dati di posizione dopo il primo render, è necessario + impostare il flag di needsUpdate come segue: +

      + +line.geometry.attributes.position.needsUpdate = true; // required after the first render + + +

      + Se vuoi modificare i valori dei dati di posizione dopo il rendering iniziale, è necessario + ricalcolare i volumi di delimitazione (bounding volumes) in modo che altre funzionalità dell'engine + come l'eliminazione del frustum di visualizzazione o gli helpers possano funzionare correttamente. +

      + +line.geometry.computeBoundingBox(); +line.geometry.computeBoundingSphere(); + + +

      + [link:https://jsfiddle.net/t4m85pLr/1/ Qui un fiddle] che mostra una linea animata che può essere adattata al tuo caso d'uso. +

      + +

      Materiali

      +
      +

      Tutti i valori costanti possono essere cambiati liberamente (come i colori, le texture, l'opacità, etc), valori che vengono inviati allo shader ad ogni frame.

      + +

      Anche i parametri relativi a GLstate possono essere cambiati in qualsiasi momento (depthTest, blending, polygonOffset, etc).

      + +

      Invece, le proprietà seguenti non possono essere modificare facilmente in fase di esecuzione (una volta che il materiale è stato renderizzato almeno una volta):

      +
        +
      • numero e tipi di costanti
        • +
      • presenza oppure no di +
          +
        • texture
          • +
        • fog
          • +
        • vertex colors
          • +
        • morphing
          • +
        • shadow map
          • +
        • alpha test
          • +
        • transparent
          • +
        +
        • +
      + +

      Le modifiche di questi richiedono la creazione di un nuovo programma di shader. Dovrai impostare:

      + material.needsUpdate = true + +

      Tieni presente che questa operazione potrebbe essere piuttosto lenta e causare scatti nel framerate (specialmente su Windows, poiché la compilazione degli shader è più lenta in DirectX che in OpenGL).

      + +

      Per creare un'esperienza più fluida puoi emulare in una certa misura le modifiche a queste funzionalità avendo valori "fittizi" come luci ad intensità zero, texture bianche, o fog a zero densità.

      + +

      È possibile cambiare liberamente il materiale utilizzato per i blocchi di geometria, tuttavia non è possibile modificare il modo in cui un oggetto è diviso in blocchi (in base ai materiali della faccia).

      + +

      Se è necessario disporre di diverse configurazioni dei materiali durante l'esecuzione:

      +

      Se il numero di materiali / blocchi è piccolo, puoi dividere l'oggetto in anticipo (per esempio capelli / faccia / corpo / vestiti superiori / pantaloni per un umano / davanti / dietro / parte superiore / occhiali / pneumatico / interni di una macchina).

      + +

      Se, invece, il numero è grande (per esempio, ogni faccia potrebbe essere potenzialmente diversa), considera una soluzione divera, come usare attributi / texture per ottenere un aspetto diverso per faccia.

      + +

      +
      + + +

      Texture

      +
      +

      Se immagini, canvas, video e texture vengono modificate devono avere il flag needsUpdate impostato come segue:

      + + texture.needsUpdate = true; + +

      Le destinazioni di rendering si aggiornano automaticamente.

      Come utilizzare il post-processing (How to use post-processing)

      + +

      + Molte applicazioni 3D visualizzano i loro oggetti 3D direttamente sullo schermo. A volte, tuttavia, si vuole applicare uno o più effetti grafici + come Depth-Of-Field, Bloom, Film Grain o vari tipi di Anti-aliasing. Il Post-processing è una soluzione ampiamente utilizzata per implementare questi effetti. + Prima di tutto, la scena viene renderizzata su un target di rendering che rappresenta un buffer nella memoria della scheda video. + Nella fase successiva, uno o più passaggi di post-processing applicano filtri ed effetti al buffer dell'immagine prima che questa venga infine renderizzata + sullo schermo. +

      +

      + three.js fornisce una soluzione di post-processing completa tramite [page:EffectComposer] per implementare tale flusso di lavoro. +

      + +

      Workflow

      + +

      + Il primo step, nel processo, è quello di importare tutti i file necessari dalla cartella degli esempi. La guida presuppone che si utilizzi + il [link:https://www.npmjs.com/package/three pacchetto npm] ufficiale di three.js. Per la nostra demo di base in questa guida abbiamo + bisogno dei seguenti file: +

      + + + import { EffectComposer } from 'three/addons/postprocessing/EffectComposer.js'; + import { RenderPass } from 'three/addons/postprocessing/RenderPass.js'; + import { GlitchPass } from 'three/addons/postprocessing/GlitchPass.js'; + + +

      + Dopo che tutti i file sono stati importati con successo, possiamo creare il nostro composer passandogli un'istanza di [page:WebGLRenderer]. +

      + + + const composer = new EffectComposer( renderer ); + + +

      + Quando viene usato un composer è necessario modificare il ciclo di animazine dell'applicazione. Invece di chiamare il metodo render di + [page:WebGLRenderer], usiamo la rispettiva controparte di [page:EffectComposer]. +

      + + + function animate() { + + requestAnimationFrame( animate ); + + composer.render(); + + } + + +

      + Il composer è pronto, ed è possibile configurare la catena di passaggi di post-processing. Questi passaggi sono i responsabili per la creazione + dell'output visivo finale dell'applicazione. Vengono elaborati nello stesso ordine in cui sono stati aggiunti/inseriti. Nel nostro esempio, l'istanza + di `RenderPass` viene eseguita per prima, poi l'istanza di `GlitchPass`. L'ultimo passaggio abilitato della catena viene automaticamente renderizzato sullo schermo. + La configurazione dei passaggi è la seguente: +

      + + + const renderPass = new RenderPass( scene, camera ); + composer.addPass( renderPass ); + + const glitchPass = new GlitchPass(); + composer.addPass( glitchPass ); + + +

      + `RenderPass` viene normalmente posizionata all'inizio della catena per fornire la scena renderizzata come input per il passaggio successivo di post-processing. + Nel nostro caso `GlitchPass` utilizzarà questi dati di immagine per applicare un effetto glitch selvaggio. Guarda questo [link:https://threejs.org/examples/webgl_postprocessing_glitch esempio live] + per vederli in azione. +

      + +

      Passi Built-in

      + +

      + È possibile utilizzare un'ampia gamma di passaggi di post-processing predefiniti forniti dall'engine. Si possono trovare nella + cartella di [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm/postprocessing postprocessing]. +

      + +

      Passi personalizzati

      + +

      + A volte si desidera scrivere uno shader di post-processing personalizzato e includerlo nella catena dei passi di post-processing. + Per questo scenario puoi utilizzare `ShaderPass`. Dopo aver importato il file e lo shader personalizzato, si può usare il seguente codice per + impostare i passaggi: +

      + + + import { ShaderPass } from 'three/addons/postprocessing/ShaderPass.js'; + import { LuminosityShader } from 'three/addons/shaders/LuminosityShader.js'; + + // later in your init routine + + const luminosityPass = new ShaderPass( LuminosityShader ); + composer.addPass( luminosityPass ); + + +

      + Il repository fornisce un file chiamato [link:https://github.com/mrdoob/three.js/blob/master/examples/jsm/shaders/CopyShader.js CopyShader], il quale è un ottimo + punto di partenza per il tuo shader personalizzato. `CopyShader` copia semplicemente il contenuto dell'immagine del buffer di lettura dell'[page:EffectComposer] + nel buffer di scrittura senza applicare alcun effetto. +

      Installazione ([name])

      + +

      + È possibile installare three.js con [link:https://www.npmjs.com/ npm] e i moderni strumenti di compilazione, o iniziare rapidamente con un hosting statico o un CDN. Per la maggior parte degli utenti fare l'installazione usando npm è la scelta migliore. +

      + +

      + Qualsiasi soluzione venga scelta, sii coerente e importa tutti i file della stessa versione della libreria. + Mescolare file provenienti da fonti diverse può causare l'inclusione di codice duplicato o addirittura rompere l'applicazione in modo imprevisto. +

      + +

      + Tutti i metodi di installazione di three.js dipendono dai moduli ES (vedi [link:https://eloquentjavascript.net/10_modules.html#h_hF2FmOVxw7 Eloquent JavaScript: ECMAScript Modules]), i quali permettono di includere nel progetto finale solo le parti della libreria necessarie. +

      + +

      Installazione tramite npm

      + +

      + Per installare il modulo npm di [link:https://www.npmjs.com/package/three three], apri il terminale nella cartella del progetto ed esegui: +

      + + + npm install three + + +

      + Il pacchetto verrà scaricato e installato. Quindi sarà pronto per essere importato nel tuo codice: +

      + + + // Opzione 1: Importa l'intera libreria di base di three.js + import * as THREE from 'three'; + + const scene = new THREE.Scene(); + + + // Opzione 2: Importa solo le parti di cui hai bisogno + import { Scene } from 'three'; + + const scene = new Scene(); + + +

      + Quando la libreria viene installata da npm, verrà quasi sempre utilizzato uno [link:https://eloquentjavascript.net/10_modules.html#h_zWTXAU93DC strumento di bundling] per combinare tutti i pacchetti richiesti dal tuo progetto in un unico file JavaScript. Sebbene con three.js si possa utilizzare qualsiasi moderno strumento di bundling, la scelta più popolare è [link:https://webpack.js.org/ webpack]. +

      + +

      + Non tutte le funzioni sono accessibili direttamente attraverso il modulo three (chiamato anche "bare import"). Altre parti popolari della libreria — come i controls, i loaders e gli effetti di post-processing — devono essere importati dalla sottocartella [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm examples/jsm]. Per saperne di più si vedano gli Esempi qui sotto. +

      + +

      + Per saperne di più sui moduli npm, consultare [link:https://eloquentjavascript.net/20_node.html#h_J6hW/SmL/a Eloquent JavaScript: Installing with npm]. +

      + +

      Installazione da CDN o hosting statico

      + +

      + La libreria three.js può essere usata senza alcun sistema di building, sia caricando i file sul tuo server web o usando un CDN esistente. Poiché la libreria si basa su moduli ES, qualsiasi script che fa riferimento ad essa deve usare type="module" come mostrato di seguito. + Inoltre è necessario anche definire un Import Map che risolva il bare module `three`. +

      + + + <script async src="https://unpkg.com/es-module-shims@1.3.6/dist/es-module-shims.js"></script> + + <script type="importmap"> + { + "imports": { + "three": "https://unpkg.com/three@<version>/build/three.module.js" + } + } + </script> + + <script type="module"> + + import * as THREE from 'three'; + + const scene = new THREE.Scene(); + + </script> + + +

      + Poiché le mappe di importazione non sono ancora supportate da tutti i browser, è necessario aggiungere il polyfill *es-module-shims.js*. +

      + +

      Addons

      + +

      + Il core di three.js è incentrato sui componenti più importanti di un engine 3D. Molti altri componenti utili - come i controls, i loaders e gli effetti post-processing - sono parte della sottocartella [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm examples/jsm]. Vengono definiti "esempi" perché, pur potendo essere utilizzati in modo immediato, sono anche destinati a essere remixati e personalizzati. Questi componenti vengono sempre mantenuti sincronizzati con la libreria principale, mentre i pacchetti di terze parti su npm sono gestiti da persone differenti e potrebbero non essere aggiornati. +

      + +

      + Non è necessario installare gli addons separatamente, ma dovranno essere importati separatamente. Se three.js è stato installato con npm, è possibile caricare il componente [page:OrbitControls] con: +

      + + + import { OrbitControls } from 'three/addons/controls/OrbitControls.js'; + + const controls = new OrbitControls( camera, renderer.domElement ); + + +

      + Se three.js è stato installato da un CDN, usare lo stesso CDN per installare altri componenti: +

      + + + <script async src="https://unpkg.com/es-module-shims@1.3.6/dist/es-module-shims.js"></script> + + <script type="importmap"> + { + "imports": { + "three": "https://unpkg.com/three@<version>/build/three.module.js", + "three/addons/": "https://unpkg.com/three@<version>/examples/jsm/" + } + } + </script> + + <script type="module"> + + import * as THREE from 'three'; + import { OrbitControls } from 'three/addons/controls/OrbitControls.js'; + + const controls = new OrbitControls( camera, renderer.domElement ); + + </script> + + +

      + È importante che tutti i file usino la stessa versione. Non devono essere importati addons diversi con versioni diverse, o usare addons che derivano da una versione differente di three.js. +

      + +

      Compatibilità

      + +

      Import CommonJS

      + +

      + La maggior parte dei bundler JavaScript moderni supportano i moduli ES di default, ma questo non è detto per bundler più vecchi. In questo caso è possibile configurare il bundler per riconoscere i moduli ES. Ad esempio [link:http://browserify.org/ Browserify] ha solo bisogno del plugin [link:https://github.com/babel/babelify babelify]. +

      + +

      Node.js

      + +

      + Poiché three.js è stato creato per il web, dipende dal browser e dalle API del DOM che non sempre esistono in Node.js. Alcuni di questi problemi possono essere risolti usando dei "tappa buchi" come [link:https://github.com/stackgl/headless-gl headless-gl], o sostituendo i componenti come [page:TextureLoader] con alternative personalizzate. Altre API del DOM potrebbero essere profondamente intrecciate con il codice che le utilizza e potrebbe essere più difficile aggirarle. Accettiamo benvolentieri le pull request semplici e gestibili per migliorare il supporto di Node.js, ma raccomandiamo di aprire prima una issue per discutere dei tuoi miglioramenti. +

      + +

      + Assicurati di aggiungere `{ "type": "module" }` al tuo `package.json` per abilitare i moduli ES nel tuo progetto Node. +

      + +

      + Questa guida mette a dispozione un flusso di lavoro consigliato per la maggior parte degli utenti, e dei suggerimenti + per affrontare i malfunzionamenti nel caso in cui non funzionasse come ci si aspetta. +

      + +

      Prima di iniziare

      + +

      + Se siete alle prime armi con la gestione di un server locale, + iniziate prima di tutto a capire [link:#manual/introduction/How-to-run-things-locally come gestire le cose a livello locale]. + Molti errori comuni nella visualizzazione dei modelli 3D possono essere evitati gestendo correttamente l'hosting dei file. +

      + +

      Workflow consigliato

      + +

      + Dove possibile, consigliamo di utilizzare il formato glTF (GL Transmission Format). + Entrambe le versioni .GLB e .GLTF sono supportate. + Il formato glTF è incentrato sulla distribuzione di asset in runtime, è compatto da trasmette e veloce da caricare. + Le carattestistiche includono mesh, materiali, texture, skin, skeleton, morph target, animazioni, luci, e camera. +

      + +

      + Modelli glTF pubblici sono disponibili su siti come + Sketchfab, o vari strumenti di sviluppo di modelli includono l'esportazione glTF: +

      + + + +

      + Se i tuoi strumenti preferiti di sviluppo dei modelli, non supportano il formato glTF, + considera di richiedere l'esportazione glTF agli autori, + o di fare un post sul thread della roadmap di glTF. +

      + +

      + Quando il formato glTF non è disponibile, i formati popolari come FBX, OBJ, o COLLADA + sono comunque disponibili e mantenuti regolarmente. +

      + +

      Caricamento

      + +

      + Solo alcuni loader (ad es. [page:ObjectLoader]) sono inclusi di default con three.js — altri devono essere aggiunti all'applicazione individualmente. +

      + + + import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'; + + +

      + Una volta importato un loader, sei pronto per aggiungere e caricare un modello alla scena. La sintassi + varia a seconda del loader utilizzato - quando vengono utilizzati altri formati, contralla gli esempi e la + documentazione del loader. Per il formato glTF, l'utilizzo con gli script globali sarebbe: +

      + + + const loader = new GLTFLoader(); + + loader.load( 'path/to/model.glb', function ( gltf ) { + + scene.add( gltf.scene ); + + }, undefined, function ( error ) { + + console.error( error ); + + } ); + + +

      + Per maggiori dettagli consulta la [page:GLTFLoader documentazione GLTFLoader]. +

      + +

      Troubleshooting

      + +

      + Hai passato ore a modellare un capolavoro artigianale, lo carichi nella pagina web e — oh no! 😭 + è distorto, scolorito o mancante. + Inizia con questi passaggi per la risoluzione dei problemi: +

      + +
        +
      1. + Controlla la console JavaScript per vedere se ci sono errori, + ed accertati di aver usato la funzione di callback `onError` del meotodo `.load()` + per visualizzare il risultato nella console. +
        2. +
      2. + Visualizza il modello in un'altra applicazione. Per il formato glTF, sono disponibili visualizzatori drag-and-drop per + three.js e + babylon.js. + Se il modello viene visualizzato correttamente in una o più applicazioni, + segnala il bug a three.js. + Se il modello non è visualizzabile in nessuna applicazione, incoraggiamo vivamente di segnalare un bug + all'applicazione utilizzata per creare il modello. +
        3. +
      3. + Prova a scalare il modello verso l'alto o il basso di un fattore di 1000. Molti modelli sono scalati diversamente, + e molti modelli di grandi dimensioni non vengono visualizzati se la telecamera si trova all'interno del modello. +
        4. +
      4. + Prova ad aggiungere e posizionare una luce nella scena. Il modello potrebbe essere nascosto nell'oscurità. +
        5. +
      5. + Cerca le richieste delle texture fallite nel tab network degli strumenti per sviluppatori del browser, + come `"C:\\Path\To\Model\texture.jpg"`. Utilizza path relativi al tuo modello come `images/texture.jpg` - + ciò potrebbe richiedere una modifica del file del modello in un editor di testo. +
        6. +
      + +

      Chiedere aiuto

      + +

      + Se hai eseguito la procedura di risoluzione dei problemi qui sopra e il tuo modello ancora non funziona, + il giusto approccio è chiedere aiuto per una soluzione più veloce. Scrivi una domanda sul + forum three.js e, quando possibile, + includi il tuo modello (o un modello più semplice con lo stesso problema) in qualsiasi formato disponibile. + Includi informazioni sufficienti per consentire a qualcun altro di riprodurre rapidamente il problema - idealmente, una demo dal vivo. +

      Trasformazioni di matrici ([name])

      + +

      + Three.js utilizza le `matrici` per codificare le trasformazioni 3D, traslazioni (posizione), rotazioni e ridimensionamento. Ogni istanza di [page:Object3D] + ha una [page:Object3D.matrix matrice] che memorizza la posizione, la rotazione e il ridimensionamento. Questa pagina descrive come aggiornare la trasformazione + di un oggetto. +

      + +

      Proprietà di convenienza e `matrixAutoUpdate`

      + +

      + Ci sono due modi per aggiornare la trasformazione di un oggetto: +

      +
        +
      1. + Modificare le proprietà `position`, `quaternion` e `scale` dell'oggetto e lasciare che three.js ricalcoli la + matrice dell'oggetto da queste proprietà: + +object.position.copy( start_position ); +object.quaternion.copy( quaternion ); + + Per impostazione predefinita, la proprietà `matrixAutoUpdate` è impostata su true e la matrice viene ricalcolata automaticamente. + Se l'oggetto è statico, o desideri controllare manualmente quando avviene il ricalcolo, è possibile ottenere prestazioni migliori se la + proprietà è impostata a false. + +object.matrixAutoUpdate = false; + + E dopo aver modificato le proprietà, aggiornare manualmente la matrice: + +object.updateMatrix(); + +
        2. +
      2. + Modificare direttamente la matrice dell'oggetto. La classe [page:Matrix4] possiede vari metodi per modificare la matrice: + +object.matrix.setRotationFromQuaternion( quaternion ); +object.matrix.setPosition( start_position ); +object.matrixAutoUpdate = false; + + Nota che, in questo caso, `matrixAutoUpdate` deve essere impostata a `false`, e devi essere sicuro di non chiamare `updateMatrix`. + La chiamata di `updateMatrix` eliminerà le modifiche manuali apportate alla matrice, ricalcolando la matrice da `position`, `scale`, e così via. +
        3. +
      + +

      Oggetto e matrici del mondo (world matrices)

      +

      + La [page:Object3D.matrix matrice] dell'oggetto memorizza la trsformazione dell'oggetto relativa al [page:Object3D.parent genitore] dell'oggetto: + per ottenere la trasformazione dell'oggetto nelle coordinate del mondo, è necessario accedere alla [page:Object3D.matrixWorld] dell'oggetto. +

      +

      + Quando la trasformazione dell'oggetto padre o dell'oggetto figlio cambia, puoi richiedere che la [page:Object3D.matrixWorld matrixWorld] dell'oggetto + figlio venga aggiornata chiamando il metodo [page:Object3D.updateMatrixWorld updateMatrixWorld](). +

      + +

      Rotazione e Quaternione

      +

      + Three.js fornisce due modi per rappresentare le rotazioni 3D: [page:Euler angoli di Eulero] e [page:Quaternion Quaternioni], + nonché metodi per la conversione tra i due. Gli angoli di Eulero sono soggetti ad un problema chiamato "gimbal lock", in cui alcune + configurazioni possono perdere un grado di libertà (impedendo all'oggetto di essere ruotato su un asse). Per questo motivo, le + rotazioni degli oggetti sono sempre memorizzate nei [page:Object3D.quaternion quaternioni] dell'oggetto. +

      +

      + Le versioni precedenti della libreria includevano una proprietà `useQuaternion` che, se impostata a false, faceva si che la + [page:Object3D.matrix matrix] dell'oggetto fosse calcolata da un angolo di Eulero. Questa pratica è deprecata, si deve invece + usare il metodo [page:Object3D.setRotationFromEuler setRotationFromEuler], il quale aggiornerà il quaternione. +

      +

      + Three.js ufficialmente utilizza il [link:https://discourse.threejs.org/ forum] e [link:http://stackoverflow.com/tags/three.js/info Stack Overflow] per richieste di aiuto. + Se hai bisogno di assistenza con qualcosa, questi sono i posti dove andare a chiedere e cercare una soluzione.

      - まず、three.jsはWeb用に作られているので、Node.jsには必ずしも存在しないブラウザやDOM APIに依存します。これらの問題のいくつかは、[link:https://github.com/stackgl/headless-gl headless-gl] のような補正ツールを使用したり、[page:TextureLoader] のようなコンポーネントをカスタムの代替品で置き換えることで解決できます。他の DOM APIは、それらを使用するコードと深く絡み合っている可能性があり、回避するのが難しくなります。Node.js - のサポートを改善するためのシンプルで保守性の高いプルリクエストを歓迎しますが、まず問題を開いて改善点を議論することをお勧めします。 + Because three.js is built for the web, it depends on browser and DOM APIs that don't always exist in Node.js. Some of these issues can be resolved by using shims like [link:https://github.com/stackgl/headless-gl headless-gl], or by replacing components like [page:TextureLoader] with custom alternatives. Other DOM APIs may be deeply intertwined with the code that uses them, and will be harder to work around. We welcome simple and maintainable pull requests to improve Node.js support, but recommend opening an issue to discuss your improvements first.

      - 第二に、Node.jsによるESモジュールのサポートは...複雑です。Node.js v12の時点では、three.jsのコアライブラリはrequire('three')でCommonJSモジュールとしてインポートすることができます。しかし、examples/jsmにあるほとんどのサンプルコンポーネントはインポートできません。Node.jsの将来のバージョンで解決されるかもしれませんが、それまでの間は、[link:https://github.com/standard-things/esm - esm]のような回避策を使用して、Node.jsアプリケーションがESモジュールを認識できるようにする必要があるでしょう。 + Make sure to add `{ "type": "module" }` to your `package.json` to enable ES6 modules in your node project.

        Testando com NPM

        + +

        + Este artigo mostra como colocar o three.js em um ambiente [link:https://nodejs.org/en/ node.js] para que você + possa executar testes automatizados. Os testes podem ser executados na linha de comando ou por + ferramentas de CI como [link:https://travis-ci.org/ Travis]. +

        + +

        A versão curta

        + +

        + Se você estiver confortável com node e npm, + + $ npm install three --save-dev + + e adicione + + const THREE = require('three'); + + para o seu teste. +

        + +

        Criar um projeto testável do zero

        +

        + Se você não estiver familiarizado com essas ferramentas, aqui está um guia rápido (para linux, o processo de instalação + será um pouco diferente do que usando o Windows, mas os comandos do NPM são idênticos). +

        + +

        Configuração básica

        +
        +
          +
        1. + Instale o [link:https://www.npmjs.org/ npm] e o nodejs. O caminho mais curto normalmente parece algo como + +$ sudo apt-get install -y npm nodejs-legacy +# fix any problems with SSL in the default registry URL +$ npm config set registry http://registry.npmjs.org/ + +
          2. + +
        2. + Crie um novo diretório de projeto + + $ mkdir test-example; cd test-example + +
          3. + +
        3. + Peça ao npm para criar um novo arquivo de projeto para você: + + $ npm init + + e aceite todas as opções default pressionando Enter em todos os prompts. + Isso criará o package.json. +

          4. + +
        4. + Experimente iniciar o recurso de teste com + +$ npm test + + Isso falhará, o que é esperado. + Se você olhar no package.json, a definição do script de teste é + + "test": "echo \"Error: no test specified\" && exit 1" + +
          5. + +
        +
        + +

        Adicionar mocha

        +
        + Vamos usar o [link:https://mochajs.org/mocha]. + +
          +
        1. + Instale o mocha com + +$ npm install mocha --save-dev + + Observe que a pasta node_modules/ é criada e suas dependências aparecem lá. + Observe também que seu package.json foi atualizado: a propriedade devDependencies + é adicionada e atualizada pelo uso de --save-dev. +

          2. + +
        2. + Edite o package.json para usar o mocha para teste. Quando o teste for chamado, queremos apenas executar + o mocha e especificar um relatório detalhado. Por padrão, isso executará qualquer coisa em test/ + (não ter a pasta test/ pode levar a um ERR! no npm, crie-a pelo comando mkdir test) + + "test": "mocha --reporter list" + +
          3. + +
        3. + Reexecute o teste com + + $ npm test + + Isso agora deve correr bem, reportando "0 passing (1ms)" + ou similar. +
          4. + +
        +
        + +

        Adicionar three.js

        +
        +
          +
        1. + Vamos baixar nossa dependência three.js com + +$ npm install three --save-dev + +
            +
          • + Se você precisar de uma versão diferente do three.js, use + + $ npm show three versions + + para listar o que está disponível. Para escolher pelo npm a versão correta, use + + $ npm install three@0.84.0 --save + + (0.84.0 nesse exemplo). --save torna isso uma dependência do projeto, em vez de + dependência dev. Veja os documentos [link:https://docs.npmjs.com/cli/v8/configuring-npm/package-json aqui] para mais informações. +
            • +
          +
          2. + +
        2. + Mocha irá procurar por testes em test/, então vamos executar + + $ mkdir test + +
          3. + +
        3. + Finalmente, precisamos de um teste JS para ser executado. Vamos adicionar um teste simples que verificará que + o objeto three.js está disponível e funcionando. Crie test/verify-three.js contendo: + +const THREE = require('three'); +const assert = require('assert'); + +describe('The THREE object', function() { + it('should have a defined BasicShadowMap constant', function() { + assert.notEqual('undefined', THREE.BasicShadowMap); + }), + + it('should be able to construct a Vector3 with default of x=0', function() { + const vec3 = new THREE.Vector3(); + assert.equal(0, vec3.x); + }) +}) + +
          4. + +
        4. + Finalmente vamos testar novamente com $ npm test. Isso deve executar os testes acima e ter sucesso, + mostrando algo como: + +The THREE object should have a defined BasicShadowMap constant: 0ms +The THREE object should be able to construct a Vector3 with default of x=0: 0ms +2 passing (8ms) + +
          5. +
        +
        + +

        Adicione seu próprio código

        +
        + Você precisa fazer três coisas: + +
          +
        1. + Escreva um teste para o comportamento esperado do seu código e coloque-o em test/. + [link:https://github.com/air/encounter/blob/master/test/Physics-test.js aqui] tem um exemplo de um projeto real. +
          2. + +
        2. + Exporte seu código funcional de forma que o nodejs possa vê-lo, para uso em conjunto com require. + Veja isso [link:https://github.com/air/encounter/blob/master/js/Physics.js aqui]. +
          3. + +
        3. + Requisite seu código no arquivo de teste, da mesma forma que fizemos um require('three') no exemplo acima. +
          4. +
        + +

        + Os itens 2 e 3 variam dependendo de como você gerencia seu código. No exemplo de Physics.js + dado acima, a parte de exportação está bem no final. Atribuímos um objeto a module.exports: +

        + +//============================================================================= +// make available in nodejs +//============================================================================= +if (typeof exports !== 'undefined') +{ + module.exports = Physics; +} + +
        + +

        Lidando com dependências

        +
        +

        + Se você já estiver usando algo como require.js ou browserify, pule esta parte. +

        +

        + Normalmente, um projeto three.js será executado no navegador. O carregamento do módulo é, portanto, feito pelo + navegador, executando um monte de tags de script. Seus arquivos individuais não precisam se preocupar + com dependências. No entanto, em um contexto nodejs, não há index.html vinculando tudo + junto, então você tem que ser explícito. +

        +

        + Se você estiver exportando um módulo que depende de outros arquivos, precisará dizer ao node para carregá-los. + Aqui está uma abordagem: +

        +
          +
        1. + No início do seu módulo, verifique se você está em um ambiente nodejs. +
          2. +
        2. + Em caso afirmativo, declare explicitamente suas dependências. +
          3. +
        3. + Caso contrário, você provavelmente está em um navegador, então não precisa fazer mais nada. +
          4. +
        + Código de exemplo de Physics.js: + +//============================================================================= +// setup for server-side testing +//============================================================================= +if (typeof require === 'function') // test for nodejs environment +{ + const THREE = require('three'); + const MY3 = require('./MY3.js'); +} + +

        Sistema de animação

        + +

        Visão geral

        + +

        + + No sistema de animação three.js, você pode animar várias propriedades de seus modelos: + os ossos (bones) de um [page:SkinnedMesh skinned e rigged model], morph targets, + diferentes propriedades de material + (cores, opacidade, booleanos), visibilidade e transformações. As propriedades animadas podem ser utilizadas com fade in, + fade out, crossfaded e warped. As escalas de peso e tempo de diferentes + animações no mesmo objeto, bem como em objetos diferentes, podem ser alteradas + independentemente. Várias animações no mesmo objeto e em objetos diferentes podem ser + sincronizadas.

        + + Para conseguir tudo isso em um sistema homogêneo, o sistema de animação three.js + [link:https://github.com/mrdoob/three.js/issues/6881 mudou completamente em 2015] + (cuidado com informações desatualizadas!), e agora tem uma arquitetura semelhante à + Unity/Unreal Engine 4. Esta página fornece uma breve visão geral dos principais componentes do + sistema e como eles trabalham juntos. + +

        + +

        Clipes de animação (Animation Clips)

        + +

        + + Se você importou com sucesso um objeto 3D animado (não importa se + bones ou morph targets ou ambos) — por exemplo, exportando-o do Blender com o + [link:https://github.com/KhronosGroup/glTF-Blender-IO glTF Blender] e + carregando-o em uma cena three.js usando [page:GLTFLoader] — um dos campos da resposta + deve ser um array chamado "animations", contendo o [page:AnimationClip AnimationClips] + para este modelo (veja uma lista de carregadores possíveis abaixo).

        + + Cada `AnimationClip` geralmente contém os dados de uma determinada atividade do objeto. Se o + mesh é um personagem, por exemplo, pode haver um AnimationClip para caminhar, um segundo + para salto, um terceiro para contornar e assim por diante. + +

        + +

        Keyframe Tracks

        + +

        + + Dentro de tal 'AnimationClip' os dados para cada propriedade animada são armazenados em um + [page:KeyframeTrack] separado. Supondo que um objeto de personagem tenha um [page:Skeleton esqueleto] (skeleton), + uma keyframe track pode armazenar os dados para as mudanças de posição do osso do antebraço + ao longo do tempo, uma faixa diferente dos dados para as mudanças de rotação do mesmo osso, uma terceira + a posição da pista, rotação ou dimensionamento de outro osso, e assim por diante. Deve ficar claro, + que um AnimationClip pode ser composto de muitas dessas tracks.

        + + Supondo que o modelo tenha morph targets (por exemplo, um + morph target mostrando um rosto amigável e outro mostrando um rosto irritado), cada track contém as + informações sobre como a [page:Mesh.morphTargetInfluences influence] de um certo morph target + muda durante a execução do clipe. + +

        + +

        Animation Mixer

        + +

        + + Os dados armazenados formam apenas a base para as animações - a reprodução real é controlada pelo + [page:AnimationMixer]. Você pode imaginar isso não apenas como um player de animações, mas + como uma simulação de um hardware como um mixer real, que pode controlar várias animações + simultaneamente, misturando-os e fundindo-os. + +

        + +

        Ações de animação (Animation Actions)

        + +

        + + O próprio `AnimationMixer` tem muito poucas propriedades e métodos (gerais), porque + pode ser controlado por [page:AnimationAction AnimationActions]. Ao configurar um + `AnimationAction` você pode determinar quando um certo `AnimationClip` deve ser reproduzido, pausado + ou parado em um dos mixers, se e com que frequência o clipe deve ser repetido, seja + executado com um fade ou uma escala de tempo, e algumas coisas adicionais, como crossfading + ou sincronização. + +

        + +

        Animação de Grupos de Objetos

        + +

        + + Se você quiser que um grupo de objetos receba um estado de animação compartilhado, você pode usar um + [page:AnimationObjectGroup]. + +

        + +

        Formatos e Loaders suportados

        + +

        + Observe que nem todos os formatos de modelo incluem animação (notadamente o OBJ não inclui), e que apenas alguns + loaders do three.js suportam sequências [page:AnimationClip AnimationClip]. Vários que tem + suporte para este tipo de animação: +

        Gerenciamento de cor

        + +

        O que é um espaço de cor?

        + +

        + Cada espaço de cor é uma coleção de várias decisões de design, escolhidas em conjunto para dar suporte a uma + grande variedade de cores, satisfazendo as restrições técnicas relacionadas à precisão e a tecnologia das telas. Ao criar um recurso 3D ou ao montar recursos 3D em uma cena, é + importante saber quais são essas propriedades e como as propriedades de um espaço de cores se relacionam + com outros espaços de cor na cena. +

        + +
        + +
        + Cores sRGB e ponto branco (D65) exibidos no diagrama de referência cromaticidade CIE 1931. + A região colorida representa uma projeção 2D da gama sRGB, que é um volume 3D. + Fonte: Wikipedia +
        +
        + +
          +
        • + + Cores primárias: As cores primárias (por exemplo, vermelho, verde, azul) não são absolutas; elas são + selecionadas a partir do espectro visível com base em restrições de precisão limitada e + capacidades dos dispositivos de exibição disponíveis. As cores são expressas como uma proporção das cores primárias. +
          • +
        • + Ponto branco: a maioria dos espaços de cores é projetada de forma que uma soma igualmente ponderada das + primárias R = G = B parecerão sem cor, ou "acromáticas". A aparência + de valores acromáticos (como branco ou cinza) dependem da percepção humana, que por sua vez depende + fortemente no contexto do observador. Um espaço de cor especifica seu "ponto branco" para equilibrar + essas necessidades. O ponto branco definido pelo espaço de cores sRGB é + [link:https://en.wikipedia.org/wiki/Illuminant_D65 D65]. +
          • +
        • + Transfer functions: depois de escolher a gama de cores e um modelo de cores, ainda precisamos + definir mapeamentos ("transfer functions") de valores numéricos para o espaço de cores. r = 0,5 + representa 50% menos iluminação física do que r = 1.0? Ou 50% menos brilhante, conforme percebido + por um olho humano médio? São coisas diferentes, e essa diferença pode ser representada como + uma função matemática. As transfer functions podem ser lineares ou não lineares, dependendo + dos objetivos do espaço de cores. sRGB define transfer functions não lineares. Aquelas + funções são às vezes aproximadas como funções gamma, mas o termo "gamma" é + ambíguo e deve ser evitado neste contexto. +
          • +
        + + Esses três parâmetros — cores primárias, ponto branco e transfer functions — definem um espaço de cores, + cada um escolhido para objetivos particulares. Tendo definido os parâmetros, alguns termos adicionais + são úteis: + +
          +
        • + Modelo de cores: Sintaxe para identificar numericamente as cores dentro da gama de cores escolhida — + um sistema de coordenadas para cores. No three.js estamos preocupados principalmente com o modelo de cor RGB, + tendo três coordenadas r, g, b ∈ [0,1] ("domínio fechado") ou + r, g, b ∈ [0,∞] ("domínio aberto"), cada um representando uma fração de uma cor primária. + Outros modelos de cores (HSL, Lab, LCH) são comumente usados ​​para controle artístico. +
          • +
        • + Gama de cores: uma vez que as cores primárias e um ponto branco tenham sido escolhidos, eles representam + um volume dentro do espectro visível (uma "gama"). Cores fora deste volume ("fora da gama") + não podem ser expressas por valores RGB de domínio fechado [0,1]. No domínio aberto [0,∞], a gama é + tecnicamente infinita. +
          • +
        + +

        + Considere dois espaços de cores muito comuns: [page:SRGBColorSpace] ("sRGB") e + [page:LinearSRGBColorSpace] ("Linear-sRGB"). Ambos usam as mesmas cores primárias e ponto branco, + e, portanto, têm a mesma gama de cores. Ambos usam o modelo de cores RGB. Eles diferem apenas + nas transfer functions — Linear-sRGB é linear em relação à intensidade da luz física. + sRGB usa as transfer functions sRGB não lineares e se assemelha mais à maneira que + o olho humano percebe a luz e a capacidade de resposta de dispositivos de exibição comuns. +

        + +

        + Essa diferença é importante. Cálculos de iluminação e outras operações de renderização devem + geralmente ocorrem em um espaço de cores linear. No entanto, cores lineares são menos eficientes para + armazenar em uma imagem ou framebuffer e não parecem corretas quando vistas por um observador humano. + Como resultado, as texturas de entrada e a imagem final renderizada geralmente usarão o método não linear + do espaço de cores sRGB. +

        + +
        +

        + ℹ️ AVISO: Embora alguns monitores modernos sejam compatíveis com gamas mais amplas, como Display-P3, + as APIs gráficas da plataforma web dependem em grande parte do sRGB. Aplicativos que usam three.js + hoje normalmente usarão apenas os espaços de cores sRGB e Linear-sRGB. +

        +
        + +

        Atribuições dos espaços de cores

        + +

        + Fluxos de trabalho lineares - necessários para métodos modernos de renderização - geralmente envolvem mais de + um espaço de cores, cada um atribuído a uma função específica. Espaços de cores lineares e não lineares são + apropriados para diferentes funções, como explicado abaixo. +

        + +

        Input do espaço de cores

        + +

        + Cores fornecidas ao three.js — de seletores de cores, texturas, modelos 3D e outras fontes — + cada um tem um espaço de cor associado. Aqueles que ainda não estão na cor de trabalho Linear-sRGB, + devem ser convertidos e as texturas devem receber a atribuição texture.encoding correta. + Certas conversões (para cores hexadecimais e CSS em sRGB) podem ser feitas automaticamente se + o modo de gerenciamento de cores herdado é desabilitado antes de inicializar as cores: +

        + + +THREE.ColorManagement.legacyMode = false; + + +
          +
        • + Materiais, luzes e shaders: cores nos materiais, luzes e shaders armazenam + componentes RGB no espaço de cores de trabalho Linear-sRGB. +
          • +
        • + Cores de vértices: [page:BufferAttribute BufferAttributes] armazena componentes RGB no + Espaço de cores de trabalho linear-sRGB. +
          • +
        • + Texturas de cores: PNG ou JPEG [page:Texture Textures] contendo informações de cores + (como .map ou .emissiveMap) usam o espaço de cores sRGB de domínio fechado e devem ser anotados com + texture.encoding = sRGBEncoding. Formatos como OpenEXR (às vezes usado para .envMap ou + .lightMap) usam o espaço de cores Linear-sRGB indicado com texture.encoding = LinearEncoding, + e podem conter valores no domínio aberto [0,∞]. +
          • +
        • + Texturas não coloridas: Texturas que não armazenam informações de cores (como .normalMap + ou .roughnessMap) não têm um espaço de cores associado e geralmente usam a textura (padrão) + como texture.encoding = LinearEncoding. Em casos raros, dados sem cor + podem ser representados com outras codificações não lineares por motivos técnicos. +
          • +
        + +
        +

        + ⚠️ AVISO: Muitos formatos para modelos 3D não funcionam de forma correta ou consistente + na definição das informações do espaço de cores. Enquanto o three.js tenta lidar com a maioria dos casos, problemas + são comuns com formatos de arquivo mais antigos. Para melhores resultados, use glTF 2.0 ([page:GLTFLoader]) + e teste modelos 3D em visualizadores on-line antecipadamente para confirmar que o recurso em si está correto. +

        +
        + +

        Espaço de cores de trabalho

        + +

        + Renderização, interpolação e muitas outras operações devem ser executadas em um domínio aberto + do espaço de cores de trabalho linear, no qual os componentes RGB são proporcionais a iluminação + física. No three.js, o espaço de cores de trabalho é Linear-sRGB. +

        + +

        Output do espaço de cores

        + +

        + A saída para um dispositivo de exibição, imagem ou vídeo pode envolver a conversão do domínio aberto + do espaço de cores de trabalho linear-sRGB para outro espaço de cores. Essa conversão pode ser feita em + uma passagem de renderização principal ([page:WebGLRenderer.outputEncoding]), ou durante o pós-processamento. +

        + + +renderer.outputEncoding = THREE.sRGBEncoding; // optional with post-processing + + +
          +
        • + Tela: as cores gravadas em um canvas WebGL para exibição devem estar no espaço sRGB + colorido. +
          • +
        • + Imagem: as cores gravadas em uma imagem devem usar o espaço de cores apropriado para + o formato e o uso. Imagens totalmente renderizadas gravadas em texturas PNG ou JPEG geralmente + usam o espaço de cores sRGB. Imagens contendo emissão, mapas de luz ou outros dados não + confinados ao intervalo [0,1] geralmente usarão o espaço de cores Linear-sRGB de domínio aberto, + e um formato de imagem compatível como OpenEXR. +
          • +
        + +
        +

        + ⚠️ AVISO: + Os render targets podem usar sRGB ou Linear-sRGB. sRGB faz + melhor uso de precisão limitada. No domínio fechado, 8 bits geralmente são suficientes para sRGB + enquanto que ≥12 bits (meio flutuante) podem ser necessários para Linear-sRGB. Se mais tarde + os estágios pipeline precisarem de entrada Linear-sRGB, as conversões adicionais podem ter um pequeno + custo de desempenho. +

        +
        + +

        Trabalhando com instâncias THREE.Color

        + +

        + Métodos de leitura ou modificação de instâncias [page:Color] assumem que os dados já estão no + espaço de cores de trabalho three.js, Linear-sRGB. Os componentes RGB e HSL são + representações diretas de dados armazenados pela instância Color e nunca são convertidos + implicitamente. Os dados de cores podem ser convertidos explicitamente com .convertLinearToSRGB() + ou .convertSRGBToLinear(). +

        + + + // RGB components (no change). + color.r = color.g = color.b = 0.5; + console.log( color.r ); // → 0.5 + + // Manual conversion. + color.r = 0.5; + color.convertSRGBToLinear(); + console.log( color.r ); // → 0.214041140 + + +

        + Com ColorManagement.legacyMode = false definido (recomendado), determinadas conversões + são feitas automaticamente. Como as cores hexadecimais e CSS geralmente são sRGB, métodos [page:Color] + irão converter automaticamente essas entradas de sRGB para Linear-sRGB em setters, ou + converter de Linear-sRGB para sRGB ao retornar hexadecimal ou CSS de getters. +

        + + + // Hexadecimal conversion. + color.setHex( 0x808080 ); + console.log( color.r ); // → 0.214041140 + console.log( color.getHex() ); // → 0x808080 + + // CSS conversion. + color.setStyle( 'rgb( 0.5, 0.5, 0.5 )' ); + console.log( color.r ); // → 0.214041140 + + // Override conversion with 'colorSpace' argument. + color.setHex( 0x808080, LinearSRGBColorSpace ); + console.log( color.r ); // → 0.5 + console.log( color.getHex( LinearSRGBColorSpace ) ); // → 0x808080 + console.log( color.getHex( SRGBColorSpace ) ); // → 0xBCBCBC + + +

        Erros comuns

        + +

        + Quando uma cor ou textura individual é configurada incorretamente, ela aparecerá mais escura ou mais clara do que + esperado. Quando o espaço de cores de saída do renderizador está mal configurado, a cena inteira pode aparecer + mais escura (por exemplo, conversão ausente para sRGB) ou mais clara (por exemplo, uma conversão dupla para sRGB com + pós-processamento). Em cada caso, o problema pode não ser uniforme e simplesmente aumentar/diminuir + a iluminação não resolve. +

        + +

        + Um problema mais sutil aparece quando ambos os espaços de cores de entrada e saída + estão incorretos — os níveis gerais de brilho podem ser bons, mas as cores podem mudar + inesperadamente sob iluminação diferente, ou o sombreamento pode parecer mais estourado e menos suave + do que o pretendido. Esses dois erros não fazem um acerto, e é importante que o trabalho + espaço de cores funcional seja linear ("cena referida") e o espaço de cores de saída seja não linear + ("exibição referida"). +

        Criando uma cena

        + +

        O objetivo dessa seção é dar uma breve introdução ao three.js. Nós iremos começar configurando uma cena (scene) com um cubo giratório. Um exemplo é apresentado no final dessa página, caso você precise de ajuda.

        + +

        Antes de começar

        + +

        Antes de começar usar o three.js, você precisa de algum lugar para mostrá-lo. Salve o HTML abaixo em um arquivo no seu computador, junto com uma cópia do [link:https://threejs.org/build/three.js three.js] na pasta js/, e abra o arquivo no navegador.

        + + + <!DOCTYPE html> + <html> + <head> + <meta charset="utf-8"> + <title>My first three.js app</title> + <style> + body { margin: 0; } + </style> + </head> + <body> + <script src="js/three.js"></script> + <script> + // Our Javascript will go here. + </script> + </body> + </html> + + +

        Isso é tudo. Todo o código abaixo vai dentro da tag <script> vazia.

        + +

        Criando a cena

        + +

        Para realmente ser capaz de exibir algum conteúdo com o three.js, nós precisamos de três coisas: cena (scene), câmera (camera) e renderizador (renderer), para que possamos então renderizar a cena com a câmera. +

        + + + const scene = new THREE.Scene(); + const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 ); + + const renderer = new THREE.WebGLRenderer(); + renderer.setSize( window.innerWidth, window.innerHeight ); + document.body.appendChild( renderer.domElement ); + + +

        Vamos tirar um momento para explicar o que está acontecendo aqui. Nós temos agora configurados a cena, nossa câmera e o renderizador.

        + +

        Existem alguns diferentes tipos de câmera no three.js. Por enquanto usaremos a `PerspectiveCamera`.

        + +

        O primeiro atributo é o `field of view`. FOV é a extensão da cena que é vista na tela em um dado momento. O valor está em graus.

        + +

        O segundo atributo é o `aspect ratio`. Você quase sempre irá usar o comprimento do elemento dividido pela sua altura, ou você terá o mesmo resultado de quando reproduz filmes antigos em uma TV widescreen - a imagem parece esmagada.

        + +

        Os próximos dois atributos são os planos de corte `near` e `far`. Isso significa que os objetos mais distantes da câmera do que o valor `far` ou mais próximos que o valor `near` não serão renderizados. Você não precisa se preocupar com isso agora, mas pode ser necessário usar outros valores em seus apps para obter uma melhor performance.

        + +

        Em seguida temos o renderizador. É aqui que a mágica acontece. Além do WebGLRenderer que usamos aqui, three.js vem com alguns outros, frequentemente usados como substitutos para usuários com navegadores antigos ou para aqueles que não possuem suporte para WebGL por algum motivo.

        + +

        Além da criação da intância do renderizador, nós também precisamos configurar o tamanho em que queremos renderizar nossa aplicação. É uma boa ideia usar o comprimento e a altura da área que queremos preencher com nossa aplicação - no nosso caso, o comprimento e altura da janela do navegador. Para aplicativos de alto desempenho, você pode fornecer valores menores para o `setSize`, como `window.innerWidth/2` e `window.innerHeight/2`, o que fará com que a aplicação seja renderizada no tamanho de um quarto do original.

        + +

        Se você deseja manter o tamanho do seu aplicativo mas renderizá-lo em uma resolução mais baixa, você pode chamar o `setSize` passando false como `updateStyle` (o terceiro argumento). Por exemplo, `setSize(window.innerWidth/2, window.innerHeight/2, false)` irá renderizar sua aplicação na metade da resolução, já que seu elemento <canvas> tem 100% de comprimento e altura.

        + +

        Por último mas não menos importante, nós adicionamos o elemento `renderer` ao nosso HTML. Este é o elemento <canvas> que o renderizador usa para exibir a cena para nós.

        + +

        "Tudo bem, mas onde está aquele cubo que você prometeu?". Vamos adicioná-lo agora.

        + + + const geometry = new THREE.BoxGeometry( 1, 1, 1 ); + const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } ); + const cube = new THREE.Mesh( geometry, material ); + scene.add( cube ); + + camera.position.z = 5; + + +

        Para criar um cubo, nós precisamos de um `BoxGeometry`. Este é um objeto que contém todos os pontos (`vertices`) e preenchimento (`faces`) do cubo. Nós vamos explorar mais sobre isso no futuro.

        + +

        Além da geometria, nós precisamos de um material para colorir. Three.js vem com vários materiais, mas vamos nos ater ao `MeshBasicMaterial` por enquanto. Todos os materiais têm um objeto de propriedades que serão aplicadas a eles. Para manter as coisas simples, forneceremos apenas um atributo de cor `0x00ff00`, que é verde. Isso funciona da mesma maneira que as cores no CSS ou no Photoshop (`hex colors`).

        + +

        A terceira coisa que precisamos é de um `Mesh`. Um mesh é um objeto que pega a geometria e aplica um material a ela, para que então possamos inseri-lo em nossa cena e move-lo livremente.

        + +

        Por padrão, quando nós chamamos `scene.add()`, o elemento que queremos adicionar será inserido nas coordenadas `(0,0,0)`. Isso faz com que a câmera e o cubo fiquem um dentro do outro. Para evitar isso, simplesmente movemos a câmera um pouco para fora.

        + +

        Renderizando a cena

        + +

        Se você copiou o código acima para o arquivo HTML criado anteriormente, você não será capaz de ver nada. Isso acontece porque ainda não estamos renderizando nada. Para isso, precisamos chamar um `render ou animate loop`.

        + + + function animate() { + requestAnimationFrame( animate ); + renderer.render( scene, camera ); + } + animate(); + + +

        Isso criará um loop que fará com que o renderizador desenhe a cena novamente toda vez que a tela for atualizada (em uma tela típica, isso significa 60 vezes por segundo). Se você é novato em escrever jogos no navegador, pode perguntar "por que não criamos um setInterval?". A questão é - nós poderíamos, mas `requestAnimationFrame` tem várias vantagens. Talvez a mais importante seja que ele pausa quando o usuário navega para outra aba do navegador, portanto, não desperdiçando seu precioso poder de processamento e vida útil da bateria.

        + +

        Animando o cubo

        + +

        Se você inseriu todo o código acima no arquivo que criamos no início, deve visualizar uma caixa verde. Vamos deixar isso tudo um pouco mais interessante rotacionando o cubo. +

        + +

        Adicione o seguinte trecho logo acima da chamada `renderer.render` na função `animate`:

        + + + cube.rotation.x += 0.01; + cube.rotation.y += 0.01; + + +

        Isso será executado a cada quadro (normalmento 60 vezes por segundo), e dará ao cubo uma boa animação de rotação. Basicamente, quaquer coisa que você queira mover ou alterar enquanto a aplicação está sendo executada tem que passar pelo loop de animação. É claro que você pode chamar outras funções de lá para que não acabe com uma função `animate` com centenas de linhas.

        + +

        O resultado

        +

        Parabéns! Agora você concluiu seu primeiro aplicativo three.js. É simples, mas você tem que começar de algum lugar.

        Criando texto

        +
        +

        + Muitas vezes, você pode precisar usar texto em sua aplicação three.js - aqui estão algumas maneiras de fazer isso. +

        +
        + +

        1. DOM + CSS

        +
        +

        + Usar HTML geralmente é a maneira mais fácil e rápida de adicionar texto. Este é o método + usado para sobreposições descritivas na maioria dos exemplos three.js. +

        +

        Você pode adicionar conteúdo para uma

        + <div id="info">Description</div> + +

        + e usar marcação CSS para posicionar absolutamente em uma posição acima de todas as outras com um + z-index, especialmente se você estiver executando o three.js em tela cheia. +

        + + +#info { + position: absolute; + top: 10px; + width: 100%; + text-align: center; + z-index: 100; + display:block; +} + + +
        + + +

        2. Usar [page:CSS2DRenderer] ou [page:CSS3DRenderer]

        +
        +

        + Use esses renderizadores para desenhar texto de alta qualidade contido em elementos DOM para sua cena three.js. + Isso é semelhante ao item 1. exceto que esses elementos de renderização podem ser integrados + mais firmemente e dinamicamente na cena. +

        +
        + + +

        3. Desenhe texto na tela e use como [page:Texture]

        +
        +

        + Use este método se deseja desenhar texto facilmente em um plano na sua cena three.js. +

        +
        + + +

        4. Crie um modelo em seu aplicativo 3D favorito e exporte para three.js

        +
        +

        Use este método se preferir trabalhar com seus aplicativos 3D e importar os modelos para o three.js.

        +
        + + +

        5. Geometria de Texto Procedural

        +
        +

        + Se você preferir trabalhar puramente em THREE.js ou criar geometrias de texto 3D + procedurais e dinâmicas, você pode criar um mesh cuja geometria é uma instância de THREE.TextGeometry: +

        +

        + new THREE.TextGeometry( text, parameters ); +

        +

        + Para que isso funcione, no entanto, seu TextGeometry precisará de uma instância de THREE.Font + para ser definido em seu parâmetro "fonte". + + Veja a página [page:TextGeometry] para mais informações sobre como isso pode ser feito, descrição de cada + um dos parâmetros aceitos e uma lista das fontes JSON que vêm com a própria distribuição THREE.js. +

        + +

        Exemplos

        + +

        + [example:webgl_geometry_text WebGL / geometry / text]
        + [example:webgl_shadowmap WebGL / shadowmap] +

        + +

        + Se o Typeface estiver desativado ou você quiser usar uma fonte que não está lá, há um tutorial + com um script python para blender que permite exportar texto para o formato JSON do Three.js: + [link:http://www.jaanga.com/2012/03/blender-to-threejs-create-3d-text-with.html] +

        + +
        + + +

        6. Fontes Bitmap

        +
        +

        + BMFonts (fontes Bitmap) permitem agrupar glifos em um único BufferGeometry. A renderização do + BMFont suporta quebra de palavras, espaçamento entre letras, kerning, campos de distância assinados com padrão + derivados, campos de distância com sinal multicanal, fontes com várias texturas e muito mais. + Veja [link:https://github.com/felixmariotto/three-mesh-ui three-mesh-ui] ou [link:https://github.com/Jam3/three-bmfont-text three-bmfont-text]. +

        +

        + As Stock Fonts estão disponíveis em projetos como + [link:https://github.com/etiennepinchon/aframe-fonts A-Frame Fonts], ou você pode criar o seu próprio + de qualquer fonte .TTF, otimizando para incluir apenas os caracteres necessários para um projeto. +

        +

        7. Troika Text

        +
        +

        + O pacote [link:https://www.npmjs.com/package/troika-three-text troika-three-text] renderiza + texto com suavização de qualidade usando uma técnica semelhante ao BMFonts, mas funciona diretamente com qualquer + arquivo de fonte .TTF ou .WOFF, para que você não precise pré-gerar uma textura de glifo offline. Também adiciona + capacidades incluindo: +

        +
          +
        • Efeitos como traços, sombras e curvatura
          • +
        • A capacidade de aplicar qualquer material three.js, até mesmo um ShaderMaterial personalizado
          • +
        • Suporte para ligaduras de fonte, scripts com letras unidas e layout da direita para a esquerda/bidirecional
          • +
        • Otimização para grandes quantidades de texto dinâmico, realizando a maior parte do trabalho fora da thread principal em um web worker

        Desenhando linhas

        +
        +

        + Digamos que você queira desenhar uma linha ou um círculo, não um wireframe [page:Mesh]. + Primeiro precisamos configurar o [page:WebGLRenderer renderizador] (renderer), a [page:Scene cena] (scene) e + a câmera (camera) (veja a página Criando uma cena). +

        + +

        + Aqui está o código que vamos usar: +

        + +const renderer = new THREE.WebGLRenderer(); +renderer.setSize( window.innerWidth, window.innerHeight ); +document.body.appendChild( renderer.domElement ); + +const camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 500 ); +camera.position.set( 0, 0, 100 ); +camera.lookAt( 0, 0, 0 ); + +const scene = new THREE.Scene(); + + +

        + A próxima coisa que vamos fazer é definir um material. + Para linhas nós temos que usar [page:LineBasicMaterial] ou [page:LineDashedMaterial]. +

        + + +//create a blue LineBasicMaterial +const material = new THREE.LineBasicMaterial( { color: 0x0000ff } ); + + +

        + Depois do material, nós vamos precisar de uma geometria com alguns vértices: +

        + + +const points = []; +points.push( new THREE.Vector3( - 10, 0, 0 ) ); +points.push( new THREE.Vector3( 0, 10, 0 ) ); +points.push( new THREE.Vector3( 10, 0, 0 ) ); + +const geometry = new THREE.BufferGeometry().setFromPoints( points ); + + +

        + Note que linhas são desenhadas entre cada par consecutivo de vértices, + mas não entre o primeiro e o último (a linha não é fechada). +

        + +

        + Agora que nós temos os pontos para duas linhas e um material, + podemos juntar tudo e formar uma linha +

        + +const line = new THREE.Line( geometry, material ); + + +

        + Tudo o que falta é adicioná-la na cena e chamar o [page:WebGLRenderer.render renderizador]. +

        + + +scene.add( line ); +renderer.render( scene, camera ); + + +

        + Agora você deve estar vendo uma seta apontando para cima, feita de duas linhas azuis. +

        FAQ

        + +

        Qual formato de modelo 3D é melhor suportado?

        +
        +

        + O formato recomendado para importar e exportar recursos é + o glTF (GL Transmission Format). Isso porque o glTF é focado na entrega de recursos em + tempo de execução, é compacto para transmitir e rápido para carregar. +

        +

        + O three.js também fornece loaders para muitos outros formatos populares como FBX, Collada ou OBJ. + No entanto, primeiro você deve sempre tentar estabelecer um fluxo de trabalho baseado em glTF em seus projetos. + Para obter mais informações, consulte [link:#manual/introduction/Loading-3D-models Carregando modelos 3D]. +

        +
        + +

        Por que existem meta tags de viewport nos exemplos?

        +
        + <meta name="viewport" content="width=device-width, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0"> + +

        + Essas tags controlam o tamanho e a escala da janela de visualização para navegadores móveis + (onde o conteúdo da página pode ser renderizado em tamanho diferente da janela de visualização visível). +

        +
        + +

        Como a escala da cena pode ser preservada no redimensionamento?

        +

        + Queremos que todos os objetos, independentemente da sua distância da câmera, apareçam do mesmo tamanho, + mesmo que a janela seja redimensionada. + + A equação chave para resolver isso é esta fórmula para a altura visível dada uma determinada distância da câmera: + + +visible_height = 2 * Math.tan( ( Math.PI / 180 ) * camera.fov / 2 ) * distance_from_camera; + + Se aumentarmos a altura da janela por uma certa porcentagem, o que queremos é que a altura visível em todas as distâncias + aumentem na mesma porcentagem. + + Isso não pode ser feito alterando a posição da câmera. Em vez disso, você tem que mudar + o campo de visão da câmera (FOV). + [link:http://jsfiddle.net/Q4Jpu/ Exemplo]. +

        + +

        Por que parte do meu objeto está invisível?

        +

        + Isso pode acontecer por causa do corte de faces. As faces têm uma orientação que decide qual lado + é qual. E o corte remove a parte traseira em circunstâncias normais. + Para verificar se este é o seu problema, altere o lado do material para THREE.DoubleSide. + + material.side = THREE.DoubleSide +

        + +

        + Por que o three.js às vezes retorna resultados estranhos para entradas inválidas? +

        +

        Como criar conteúdo de VR

        + +

        + Este guia fornece uma breve visão geral dos componentes básicos de uma aplicação de VR baseada na web + feita com three.js. +

        + +

        Workflow

        + +

        + Primeiro, você deve incluir [link:https://github.com/mrdoob/three.js/blob/master/examples/jsm/webxr/VRButton.js VRButton.js] + em seu projeto. +

        + + +import { VRButton } from 'three/addons/webxr/VRButton.js'; + + +

        + *VRButton.createButton()* faz duas coisas importantes: Cria um botão que indica + compatibilidade com VR. Além disso, inicia uma sessão de VR se o usuário ativar o botão. A única coisa que você tem + fazer é adicionar a seguinte linha de código ao seu aplicativo. +

        + + +document.body.appendChild( VRButton.createButton( renderer ) ); + + +

        + Em seguida, você deve informar sua instância do `WebGLRenderer` para habilitar a renderização XR. +

        + + +renderer.xr.enabled = true; + + +

        + Finalmente, você precisa ajustar seu loop de animação, pois não podemos usar nossa conhecida função + *window.requestAnimationFrame()*. Para projetos de VR usamos [page:WebGLRenderer.setAnimationLoop setAnimationLoop]. + O código mínimo fica assim: +

        + + +renderer.setAnimationLoop( function () { + + renderer.render( scene, camera ); + +} ); + + +

        Como descartar objetos

        + +

        + Um aspecto importante para aumentar o desempenho e evitar vazamentos de memória em sua aplicação é o descarte de entidades da biblioteca não utilizadas. + Sempre que você cria uma instância do tipo *three.js*, você aloca uma certa quantidade de memória. No entanto, o *three.js* cria para objetos específicos, + como geometrias ou materiais, entidades relacionadas ao WebGL como buffers ou programas de shader que são necessários para renderização. É importante + destacar que esses objetos não são liberados automaticamente. Em vez disso, o aplicativo precisa usar uma API especial para liberar esses recursos. + Este guia fornece uma breve visão geral sobre como essa API é utilizada e quais objetos são relevantes nesse contexto. +

        + +

        Geometrias (Geometries)

        + +

        + Uma geometria geralmente representa informações de vértices definidas como uma coleção de atributos. *three.js* cria internamente um objeto do tipo [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLBuffer WebGLBuffer] + para cada atributo. Essas entidades são excluídas apenas se você chamar [page:BufferGeometry.dispose](). Se uma geometria se tornar obsoleta em seu aplicativo, + execute o método para liberar todos os recursos relacionados. +

        + +

        Materiais (Materials)

        + +

        + Um material define como os objetos são renderizados. *three.js* usa as informações de uma definição de material para construir um shader para a renderização. + Os shaders só podem ser excluídos se o respectivo material for descartado. Por motivos de desempenho, o *three.js* tenta reutilizar + shaders, se possível. Portanto, um shader só é excluído se todos os materiais relacionados forem descartados. Você pode indicar o descarte de um material + executando [page:Material.dispose](). +

        + +

        Texturas (Textures)

        + +

        + O descarte de um material não afeta as texturas. Eles são manuseados separadamente, pois uma única textura pode ser usada por vários materiais ao mesmo tempo. + Sempre que você cria uma instância de [page:Texture], o three.js cria internamente uma instância de [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLTexture WebGLTexture]. + Semelhante aos buffers, este objeto só pode ser excluído chamando [page:Texture.dispose](). +

        + +

        + Se você usar uma `ImageBitmap` como fonte de dados da textura, você deve chamar [link:https://developer.mozilla.org/en-US/docs/Web/API/ImageBitmap/close ImageBitmap.close]() no nível da aplicação para descartar todos os recursos relacionados à CPU. + Uma chamada automatizada de `ImageBitmap.close()` em [page:Texture.dispose]() não é possível, pois o bitmap da imagem se torna inutilizável e o mecanismo não tem como saber se o bitmap da imagem é usado em outro lugar. +

        + +

        Render Targets

        + +

        + Objetos do tipo [page:WebGLRenderTarget] não apenas alocam uma instância de [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLTexture WebGLTexture], mas também + [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLFramebuffer WebGLFramebuffer]s e [link:https://developer.mozilla.org/en-US/docs/Web/API WebGLRenderbuffer]s + para realizar render targets personalizados. Esses objetos são desalocados apenas executando [page:WebGLRenderTarget.dispose](). +

        + +

        Diversos

        + +

        + Existem outras classes da pasta de exemplos como controles ou passes de pós-processamento que fornecem métodos `dispose()` para remover listeners de eventos internos + ou renderizar targets. Em geral, é recomendado verificar a API ou a documentação de uma classe e procurar o método `dispose()`. Se existir, você deve usá-lo ao limpar as coisas. +

        + +

        FAQ

        + +

        Por que o *three.js* não pode descartar objetos automaticamente?

        + +

        + Esta pergunta foi feita muitas vezes pela comunidade, por isso é importante esclarecer este assunto. O fato é que o *three.js* não conhece o tempo de vida ou o escopo + das entidades criadas pelo usuário, como geometrias ou materiais. Isso é responsabilidade do aplicativo. Por exemplo, mesmo que um material não seja usado atualmente para renderização, + ele pode ser necessário no próximo quadro. Portanto, se o aplicativo decidir que um determinado objeto pode ser excluído, ele deve notificar a engine chamando o respectivo + método `dispose()`. +

        + +

        A remoção de um mesh da cena também descarta sua geometria e material?

        + +

        + Não, você precisa descartar explicitamente a geometria e o material via *dispose()*. Tenha em mente que geometrias e materiais podem ser compartilhados entre objetos 3D como meshes. +

        + +

        *three.js* fornece informações sobre a quantidade de objetos em cache?

        + +

        + Sim. É possível avaliar [page:WebGLRenderer.info], uma propriedade especial do renderizador (renderer) com uma série de informações estatísticas sobre a memória da placa gráfica + e o processo de renderização. Entre outras coisas, ele informa quantas texturas, geometrias e shaders são armazenados internamente. Se você notar problemas de desempenho + em seu aplicativo, é uma boa ideia depurar essa propriedade para identificar facilmente um vazamento de memória. +

        + +

        O que acontece quando você chama `dispose()` em uma textura, mas a imagem ainda não foi carregada?

        + +

        + Os recursos internos para uma textura são alocados apenas se a imagem estiver totalmente carregada. Se você descartar uma textura antes de carregar a imagem, + nada acontece. Nenhum recurso foi alocado, portanto, também não há necessidade de limpeza. +

        + +

        O que acontece quando eu chamo `dispose()` e uso o respectivo objeto posteriormente?

        + +

        + Os recursos internos excluídos serão criados novamente pela engine. Portanto, nenhum erro em tempo de execução ocorrerá, mas você poderá notar um impacto negativo no desempenho do quadro atual, + especialmente quando shaders precisam ser compilados. +

        + +

        Como devo gerenciar objetos *three.js* em minha aplicação? Quando eu sei como descartar as coisas?

        + +

        + Em geral, não existe uma recomendação definitiva para isso. Depende muito do caso específico de uso quando será mais apropriado chamar `dispose()`. É importante destacar que + nem sempre é necessário descartar objetos o tempo todo. Um bom exemplo disso é um jogo que consiste de vários níveis. Um bom momento para descarte de objetos é quando + ocorre uma mudança de nível. A aplicação pode percorrer a cena antiga e descartar todos os materiais, geometrias e texturas obsoletos. Como mencionado na seção anterior, não + ocorrerá um erro em tempo de execução se você descartar um objeto que ainda está em uso. A pior coisa que pode acontecer é a queda de desempenho para um único quadro. +

        + +

        Exemplos que demonstram o uso de dispose()

        Como executar localmente

        + +

        + Se você usar apenas geometrias procedurais e não carregar nenhuma textura, + as páginas web devem funcionar direto do sistema de arquivos, bastando clicar duas vezes + no arquivo HTML em um gerenciador de arquivos para então funcionar no navegador (você verá file:///yourFile.html na barra de endereço). +

        + +

        Conteúdo carregado de arquivos externos

        + +
        +

        + Se você carregar modelos ou texturas de arquivos externos, devido a [link:http://en.wikipedia.org/wiki/Same_origin_policy same origin policy] + dos navegadores, o carregamento de um sistema de arquivos falhará com uma exceção de segurança. +

        + +

        + Para resolver isso, execute os arquivos de um servidor web local. Isso permitirá acessar a página por: +

        + +

        + http://localhost/yourFile.html +

        + +

        + Embora também seja possível alterar as configurações de segurança do navegador ao invés de executar + um servidor local, não recomendamos essa abordagem. Isso pode abrir seu dispositivo para vulnerabilidades, + se o mesmo navegador é usado para navegação regular na web. O uso de um servidor local é uma prática padrão + em desenvolvimento web e explicamos abaixo como instalar e usar um servidor local. +

        Como atualizar as coisas

        +
        +

        Todos os objetos, por padrão, atualizam automaticamente suas matrizes se + forem adicionados à cena (scene) dessa forma

        + +const object = new THREE.Object3D(); +scene.add( object ); + + ou se eles são filhos de outro objeto que foi adicionado à cena: + +const object1 = new THREE.Object3D(); +const object2 = new THREE.Object3D(); + +object1.add( object2 ); +scene.add( object1 ); //object1 and object2 will automatically update their matrices + +
        + +

        + No entanto, se você sabe que o objeto será estático, pode desativar este recurso e atualizar + a matriz de transformação manualmente apenas quando necessário. +

        + + +object.matrixAutoUpdate = false; +object.updateMatrix(); + + +

        BufferGeometry

        +
        +

        + BufferGeometries armazenam informações (tais como posições de vértice, índice de faces, normais, cores, + UVs, e quaisquer outros atributos personalizados) em [page:BufferAttribute buffers] - isto é, + [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays arrays tipados]. + Isso os torna geralmente mais rápidos do que os Geometries padrão, ao custo de serem um pouco mais difíceis de + trabalhar. +

        +

        + Com relação à atualização dos BufferGeometries, o mais importante é entender que + você não pode redimensionar buffers (isso é muito custoso, sendo basicamente o equivalente a criar uma nova geometria). + No entanto, você pode atualizar o conteúdo dos buffers. +

        +

        + Isso significa que se você sabe que um atributo do seu BufferGeometry vai crescer, digamos o número de vértices, + você deve pré-alocar um buffer grande o suficiente para conter quaisquer novos vértices que possam ser criados. + É claro, isso também significa que haverá um tamanho máximo para o seu BufferGeometry - + não há como criar um BufferGeometry que possa ser estendido de forma eficiente indefinidamente. +

        +

        + Usaremos o exemplo de uma linha que é estendida em tempo de renderização. Vamos alocar espaço + no buffer para 500 vértices, mas desenhando apenas dois primeiro, usando [page:BufferGeometry.drawRange]. +

        + +const MAX_POINTS = 500; + +// geometry +const geometry = new THREE.BufferGeometry(); + +// attributes +const positions = new Float32Array( MAX_POINTS * 3 ); // 3 vertices per point +geometry.setAttribute( 'position', new THREE.BufferAttribute( positions, 3 ) ); + +// draw range +const drawCount = 2; // draw the first 2 points, only +geometry.setDrawRange( 0, drawCount ); + +// material +const material = new THREE.LineBasicMaterial( { color: 0xff0000 } ); + +// line +const line = new THREE.Line( geometry, material ); +scene.add( line ); + +

        + Em seguida, adicionaremos aleatoriamente pontos à linha usando um padrão como: +

        + +const positions = line.geometry.attributes.position.array; + +let x, y, z, index; +x = y = z = index = 0; + +for ( let i = 0, l = MAX_POINTS; i < l; i ++ ) { + + positions[ index ++ ] = x; + positions[ index ++ ] = y; + positions[ index ++ ] = z; + + x += ( Math.random() - 0.5 ) * 30; + y += ( Math.random() - 0.5 ) * 30; + z += ( Math.random() - 0.5 ) * 30; + +} + +

        + Se você quiser alterar o número de pontos renderizados após a primeira renderização, faça o seguinte: +

        + +line.geometry.setDrawRange( 0, newValue ); + +

        + Se você deseja alterar os valores dos dados de posição após a primeira renderização, você precisa + definir a propriedade needsUpdate assim: +

        + +line.geometry.attributes.position.needsUpdate = true; // required after the first render + + +

        + Se você alterar os valores dos dados de posição após a renderização inicial, pode ser necessário recalcular + os limites de volume para que outros recursos da engine, como view frustum culling ou helpers, + funcionem corretamente +

        + +line.geometry.computeBoundingBox(); +line.geometry.computeBoundingSphere(); + + +

        + [link:https://jsfiddle.net/t4m85pLr/1/ O fiddle] mostra uma linha animada que você pode adaptar ao seu caso de uso. +

        + +
        + +

        Materiais (Materials)

        +
        +

        + Todos os valores uniformes podem ser alterados livremente (por exemplo, cores, texturas, opacidade, etc), + os valores são enviados para o shader a cada quadro. +

        + +

        + Também os parâmetros relacionados ao GLstate podem mudar a qualquer momento + (depthTest, blending, polygonOffset, etc). +

        + +

        + As seguintes propriedades não podem ser alteradas facilmente em tempo de execução + (uma vez que o material é renderizado pelo menos uma vez): +

        +
          +
        • números e tipos de uniformes
          • +
        • presença ou não de +
            +
          • textura (texture)
            • +
          • fog
            • +
          • cores dos vértices (vertex colors)
            • +
          • morphing
            • +
          • shadow map
            • +
          • alpha test
            • +
          • transparent
            • +
          +
          • +
        + +

        + Mudanças nestas propriedades requerem a construção de um novo programa de shader. Você precisará definir

        + material.needsUpdate = true + +

        + Tenha em mente que isso pode ser bastante lento e induzir lags na taxa de quadros (especialmente no Windows, pois a compilação do shader é mais lenta no DirectX do que no OpenGL). +

        + +

        + Para uma experiência mais suave, você pode emular alterações nessas propriedades + até certo ponto, por ter valores "fictícios" como luzes de intensidade zero, texturas brancas ou fog de densidade zero. +

        + +

        + Você pode alterar livremente o material usado para partes da geometria, + no entanto, você não pode alterar como um objeto é dividido em partes (de acordo com os materiais da face). +

        + +

        Se você precisar ter diferentes configurações de materiais durante o tempo de execução:

        +

        + Se o número de materiais / partes for pequeno, você pode pré-dividir o objeto + de antemão (por exemplo, cabelo / rosto / corpo / roupa superior / calças para um humano, + frente / laterais /topo / vidro / pneu / interior para um carro). +

        + +

        + Se o número for grande (por exemplo, cada rosto pode ser potencialmente diferente), + considere uma solução diferente, como usar atributos / texturas para produzir diferenças + nos rostos. +

        + +

        Exemplos

        +

        + [example:webgl_materials_car WebGL / materials / car]
        + [example:webgl_postprocessing_dof WebGL / webgl_postprocessing / dof] +

        +
        + + +

        Texturas

        +
        +

        + Imagem, canvas, vídeo e dados de textura precisam ter a seguinte + propriedade definida se eles forem alterados: +

        + + texture.needsUpdate = true; + +

        Os alvos de renderização são atualizados automaticamente.

        + +

        Exemplos

        +

        + [example:webgl_materials_video WebGL / materials / video]
        + [example:webgl_rtt WebGL / rtt] +

        + +
        + + +

        Câmeras

        +
        +

        + A posição e o alvo de uma câmera são atualizados automaticamente. Se você precisa mudar +

        +
          +
        • + fov +
          • +
        • + aspect +
          • +
        • + near +
          • +
        • + far +
          • +
        +

        + então você precisará recalcular a matriz de projeção: +

        + +camera.aspect = window.innerWidth / window.innerHeight; +camera.updateProjectionMatrix(); + +

        Como usar o pós-processamento

        + +

        + Muitas aplicações three.js renderizam seus objetos 3D diretamente na tela. Às vezes, no entanto, você deseja aplicar um ou mais efeitos gráficos + como Depth-Of-Field, Bloom, Film Grain ou vários tipos de Anti-aliasing. + + O pós-processamento é uma abordagem amplamente utilizada para implementar tais efeitos. Primeiro, a cena é renderizada para um render target que representa + um buffer na memória da placa de vídeo. Na próxima etapa, um ou mais passos de pós-processamento aplicam filtros e efeitos ao buffer de imagem antes que ele seja renderizado para a tela. +

        +

        + three.js fornece uma solução completa de pós-processamento via [page:EffectComposer] para implementar esse workflow. +

        + +

        Workflow

        + +

        + A primeira etapa do processo é importar todos os arquivos necessários do diretório de exemplos. Este guia assume que você está usando o + pacote [link:https://www.npmjs.com/package/three npm] do three.js. Para nossa demonstração básica, precisamos dos seguintes arquivos. +

        + + + import { EffectComposer } from 'three/addons/postprocessing/EffectComposer.js'; + import { RenderPass } from 'three/addons/postprocessing/RenderPass.js'; + import { GlitchPass } from 'three/addons/postprocessing/GlitchPass.js'; + + +

        + Depois que todos os arquivos forem importados com sucesso, podemos criar nosso composer passando uma instância de [page:WebGLRenderer]. +

        + + + const composer = new EffectComposer( renderer ); + + +

        + Ao usar um composer, é necessário alterar o loop de animação da aplicação. Em vez de chamar o método render de + [page:WebGLRenderer], agora usamos a respectiva contraparte de [page:EffectComposer]. +

        + + + function animate() { + + requestAnimationFrame( animate ); + + composer.render(); + + } + + +

        + Nosso composer já está pronto para que seja possível configurar a cadeia de passos de pós-processamento. Esses passos são responsáveis ​​por criar + a saída visual final do aplicativo. Eles são processados ​​na ordem de sua adição/inserção. Em nosso exemplo, a instância de `RenderPass` + é executada primeiro e depois a instância de `GlitchPass`. A última passagem habilitada na cadeia é renderizada automaticamente na tela. A configuração + dos passos fica assim: +

        + + + const renderPass = new RenderPass( scene, camera ); + composer.addPass( renderPass ); + + const glitchPass = new GlitchPass(); + composer.addPass( glitchPass ); + + +

        + O `RenderPass` é normalmente colocado no início da cadeia para fornecer a cena renderizada como entrada para a próxima etapa de pós-processamento. No nosso caso, + o `GlitchPass` usará esses dados de imagem para aplicar um efeito de glitch selvagem. Confira este [link:https://threejs.org/examples/webgl_postprocessing_glitch exemplo] + para vê-lo em ação. +

        + +

        Passes integrados

        + +

        + Você pode usar uma ampla variedade de passos de pós-processamento predefinidos fornecidos pela engine. Estão localizados no diretório + [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm/postprocessing postprocessing]. +

        + +

        Passos Personalizados

        + +

        + Às vezes, você deseja escrever um shader de pós-processamento personalizado e incluí-lo na cadeia de passos de pós-processamento. Para este cenário, + você pode utilizar o `ShaderPass`. Depois de importar o arquivo e seu shader personalizado, você pode usar o código a seguir para configurar o passo. +

        + + + import { ShaderPass } from 'three/addons/postprocessing/ShaderPass.js'; + import { LuminosityShader } from 'three/addons/shaders/LuminosityShader.js'; + + // later in your init routine + + const luminosityPass = new ShaderPass( LuminosityShader ); + composer.addPass( luminosityPass ); + + +

        + O repositório fornece um arquivo chamado [link:https://github.com/mrdoob/three.js/blob/master/examples/jsm/shaders/CopyShader.js CopyShader] que é um + bom código inicial para seu próprio shader personalizado. `CopyShader` apenas copia o conteúdo da imagem do buffer de leitura do [page:EffectComposer] + para seu buffer de gravação sem aplicar nenhum efeito. +

        Instalação

        + +

        Você pode instalar o three.js através do [link:https://www.npmjs.com/ npm] e modernas ferramentas de build ou começar rapidamente apenas com hospedagem estática ou um CDN. Para a maioria dos usuários, instalar pelo npm é a melhor opção.

        + +

        Seja qual for a maneira que escolher, seja consistente e importe todos os arquivos na mesma versão da biblioteca. A mistura de arquivos de versões diferentes pode causar a inclusão de código duplicado ou até mesmo quebrar a aplicação de maneiras inesperadas.

        + +

        Todos os métodos de instalação do three.js dependem dos ES modules (veja [link:https://eloquentjavascript.net/10_modules.html#h_hF2FmOVxw7 Eloquent JavaScript: ECMAScript Modules]), que permitem incluir somente as partes necessárias da biblioteca no projeto final.

        + +

        Instalar pelo npm

        + +

        + Para instalar o módulo do npm do [link:https://www.npmjs.com/package/three three], abra uma janela do terminal na sua pasta do projeto e execute: +

        + + + npm install three + + +

        + O pacote será baixado e instalado. Então você estará pronto para importar no seu código: +

        + + + // Option 1: Import the entire three.js core library. + import * as THREE from 'three'; + + const scene = new THREE.Scene(); + + + // Option 2: Import just the parts you need. + import { Scene } from 'three'; + + const scene = new Scene(); + + +

        Ao instalar a partir do npm, você quase sempre usará algum tipo de [link:https://eloquentjavascript.net/10_modules.html#h_zWTXAU93DC ferramenta de build] para combinar todos os pacotes que seu projeto precisa em um único arquivo JavaScript. Embora alguns modernos empacotadores JavaScript possam ser usados com o three.js, a escolha mais popular é o [link:https://webpack.js.org/ webpack].

        + +

        Nem todos os recursos são acessados diretamente pelo módulo three. Outras partes populares da biblioteca - tais como controls, loaders e post-processing effects - devem ser importados da subpasta [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm examples/jsm]. Para aprender mais, veja o Exemplo abaixo.

        + +

        Aprenda mais sobre módulos do npm em [link:https://eloquentjavascript.net/20_node.html#h_J6hW/SmL/a Eloquent JavaScript: Installing with npm].

        + +

        Instalar através de CDN ou hospedagem estática

        + +

        A biblioteca three.js pode ser utilizada sem nenhum sistema de build, seja fazendo o upload dos arquivos para seu próprio servidor web ou usando um CDN existente. Como a biblioteca depende dos ES modules, qualquer script que faça referência a eles deve usar type="module" como mostrado abaixo. Também é necessário definir um mapa de importação que resolva a importação direta do `three`.

        + + + <script async src="https://unpkg.com/es-module-shims@1.3.6/dist/es-module-shims.js"></script> + + <script type="importmap"> + { + "imports": { + "three": "https://unpkg.com/three@<version>/build/three.module.js" + } + } + </script> + + <script type="module"> + + import * as THREE from 'three'; + + const scene = new THREE.Scene(); + + </script> + + +

        + Nem todos os recursos disponíveis são acessados diretamente através do módulo three. Outras partes populares da biblioteca - tais como controls, loaders e post-processing effects - devem ser importados da subpasta [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm examples/jsm]. Para aprender mais, veja o Exemplo abaixo. +

        + +

        + Como os mapas de importação ainda não são suportados por todos os navegadores, é necessário adicionar o polyfill *es-module-shims.js*. +

        + +

        Addons

        + +

        + O núcleo do three.js está focado nos componentes mais importantes de uma engine 3D. Muitos outros componentes úteis - como controls, loaders e post-processing effects - fazem parte da pasta [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm examples/jsm]. Eles são chamados de "exemplos" porque embora você possa usá-los diretamente, eles também podem ser remixados e personalizados. Esses componentes são sempre mantidos em sincronia com a biblioteca principal, enquanto pacotes semelhantes de terceiros no npm são mantidos por pessoas diferentes e podem estar desatualizados. +

        + +

        + Os addons não precisam ser instalados separadamente, mas precisam ser importados separadamente. Se o three.js foi instalado com npm, você pode carregar o componente [page:OrbitControls] com: +

        + + + import { OrbitControls } from 'three/addons/controls/OrbitControls.js'; + + const controls = new OrbitControls( camera, renderer.domElement ); + + +

        Se o three.js foi instalado de um CDN, use o mesmo CDN para instalar outros componentes:

        + + + <script async src="https://unpkg.com/es-module-shims@1.3.6/dist/es-module-shims.js"></script> + + <script type="importmap"> + { + "imports": { + "three": "https://unpkg.com/three@<version>/build/three.module.js", + "three/addons/": "https://unpkg.com/three@<version>/examples/jsm/" + } + } + </script> + + <script type="module"> + + import * as THREE from 'three'; + import { OrbitControls } from 'three/addons/controls/OrbitControls.js'; + + const controls = new OrbitControls( camera, renderer.domElement ); + + </script> + + +

        + É importante que todos os arquivos utilizem a mesma versão. Não importe diferentes addons de diferentes versões, ou use addons de uma versão diferente que a própria biblioteca three.js. +

        + +

        Compatibilidade

        + +

        Importação CommonJS

        + +

        + Embora a maioria dos bundlers JavaScript modernos atualmente suportem os ES modules por padrão, algumas ferramentas de build mais antigas podem não suportar. Nesses casos você provavelmente pode configurar o bundler para entender os ES modules: [link:http://browserify.org/ Browserify] precisa apenas do plugin [link:https://github.com/babel/babelify babelify], por exemplo. +

        + +

        Node.js

        + +

        + Como o three.js foi desenvolvido para a web, ele depende do navegador e das APIs DOM que nem sempre existem no Node.js. Alguns desses problemas podem ser resolvidos usando ferramentas como [link:https://github.com/stackgl/headless-gl headless-gl], ou substituindo componentes como [page:TextureLoader] por alternativas personalizadas. Outras APIs DOM podem ser profundamente entrelaçadas com o código que as utiliza, e serão mais difíceis de contornar. Aceitamos solicitações de pull simples e fáceis de manter para melhorar o suporte ao Node.js, mas recomendo abrir uma issue para discutir suas melhorias primeiro. +

        + +

        + Certifique-se de adicionar `{ "type": "module" }` ao seu `package.json` para habilitar os ES6 modules em seu projeto Node.js. +

        Carregando modelos 3D

        + +

        + Os modelos 3D estão disponíveis em centenas de formatos de arquivo, cada um com diferentes + propósitos, recursos variados e complexidade variável. Embora o + + three.js forneça muitos loaders, escolher o formato e o fluxo de trabalho certos economizará tempo e frustração mais tarde. + Alguns formatos são difíceis de trabalhar, ineficientes para experiências em tempo real + ou simplesmente não são totalmente suportados por enquanto. +

        + +

        + Este guia fornece um fluxo de trabalho recomendado para a maioria dos usuários e sugestões + do que tentar se as coisas não correrem como o esperado. +

        + +

        Antes de começar

        + +

        + Se você é iniciante na execução de um servidor local, comece com + [link:#manual/introduction/How-to-run-things-locally Como executar localmente] + primeiro. Muitos erros comuns de visualização de modelos 3D podem ser evitados hospedando arquivos + corretamente. +

        + +

        Fluxo de trabalho recomendado

        + +

        + Sempre que possível, recomendamos o uso do glTF (GL Transmission Format). Ambas versões do formato, + .GLB e .GLTF, são bem suportadas. + Como o glTF está focado na entrega de recursos em tempo de execução, + ele é compacto para transmitir e rápido para carregar. Seus recursos incluem meshs, materiais, + texturas, skins, skeletons, morph targets, animações, luzes e câmeras. +

        + +

        + Os arquivos glTF de domínio público estão disponíveis em sites como + + Sketchfab, ou várias ferramentas que incluem exportação glTF: +

        + + + +

        + Se suas ferramentas preferidas não suportam glTF, considere solicitar exportação de glTF para os autores, + ou postar no glTF roadmap thread. +

        + +

        + Quando o glTF não é uma opção, formatos populares como FBX, OBJ ou COLLADA + também estão disponíveis e são mantidos regularmente. +

        + +

        Carregando

        + +

        + Apenas alguns poucos loaders (por exemplo [page:ObjectLoader]) são incluídos por padrão com o + three.js — outros devem ser adicionados ao seu aplicativo individualmente. +

        + + + import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'; + + +

        + Depois de importar um loader você está pronto para adicionar um modelo à sua cena. A sintaxe varia entre + loaders diferentes — ao usar outro formato, verifique os exemplos e a documentação para esse loader. + Para glTF, o uso com scripts globais ficaria: +

        + + + const loader = new GLTFLoader(); + + loader.load( 'path/to/model.glb', function ( gltf ) { + + scene.add( gltf.scene ); + + }, undefined, function ( error ) { + + console.error( error ); + + } ); + + +

        + Veja a documentação [page:GLTFLoader GLTFLoader] para mais detalhes. +

        + +

        Solução de problemas

        + +

        + Você passou horas modelando uma obra-prima artesanal, você a carrega em + uma página web e — ah, não! 😭 Está distorcido, descolorido ou totalmente ausente. + Comece com estas etapas de solução de problemas: +

        + +
          +
        1. + Verifique se há erros no console JavaScript e certifique-se de ter usado um + callback `onError` ao chamar `.load()` para logar o resultado. +
          2. +
        2. + Visualize o modelo em outro aplicativo. Para glTF, visualizadores drag-and-drop + estão disponíveis para + three.js e + babylon.js. + Se o modelo aparece corretamente em um ou mais aplicativos, + registre um bug do three.js. + Se o modelo não puder ser mostrado em nenhum aplicativo, recomendamos + registrar um bug com o aplicativo usado para criar o modelo. +
          3. +
        3. + Tente dimensionar o modelo para cima ou para baixo por um fator de 1.000. Muitos modelos são + dimensionados de forma diferente, e modelos grandes podem não aparecer se a câmera estiver + dentro do modelo. +
          4. +
        4. + Tente adicionar e posicionar uma fonte de luz. O modelo pode estar escondido no escuro. +
          5. +
        5. + Procure requisições de textura com falha na aba network, como + `"C:\\Path\To\Model\texture.jpg"`. Use caminhos relativos ao seu + modelo em vez disso, tal como `images/texture.jpg` — + isso pode exigir edição do arquivo de modelo em um editor de texto. +
          6. +
        + +

        Pedindo ajuda

        + +

        + Se você passou pelo processo de solução de problemas acima e seu modelo + ainda não está funcionando, uma abordagem correta para pedir ajuda fará com que você + tenha uma solução mais rápida. Poste uma pergunta no + fórum three.js + e, sempre que possível, + inclua seu modelo (ou um modelo mais simples com o mesmo problema) em qualquer formato que + você tiver disponível. Inclua informações suficientes para outra pessoa reproduzir + o problema rapidamente - idealmente, uma demonstração ao vivo. +

        Transformações de matriz

        + +

        + Three.js usa `matrizes` para codificar transformações 3D --- translações (posição), rotações e dimensionamento. + Cada instância de [page:Object3D] tem uma [page:Object3D.matrix matriz] (matrix) que armazena a + posição, rotação e escala. Esta página descreve como atualizar a transformação de um objeto. +

        + +

        Propriedades de conveniência e `matrixAutoUpdate`

        + +

        + Existem duas maneiras de atualizar a transformação de um objeto: +

        +
          +
        1. + Modifique as propriedades `position`, `quaternion` e `scale` do objeto e deixe o three.js recalcular + a matriz do objeto a partir destas propriedades: + +object.position.copy( start_position ); +object.quaternion.copy( quaternion ); + + Por padrão, a propriedade `matrixAutoUpdate` é definida como verdadeira e a matriz será recalculada automaticamente. + Se o objeto é estático, ou você deseja controlar manualmente quando ocorre o recálculo, um melhor desempenho pode ser obtido configurando a propriedade false: + +object.matrixAutoUpdate = false; + + E depois de alterar qualquer propriedade, atualize manualmente a matriz: + +object.updateMatrix(); + +
          2. +
        2. + Modifique a matriz do objeto diretamente. A classe [page:Matrix4] tem vários métodos para modificar a matriz: + +object.matrix.setRotationFromQuaternion( quaternion ); +object.matrix.setPosition( start_position ); +object.matrixAutoUpdate = false; + + Observe que `matrixAutoUpdate` deve ser definido como `false` neste caso, e você deve ter certeza de não chamar `updateMatrix`. Chamar `updateMatrix` irá destruir as alterações manuais feitas na matriz, recalculando a matriz de `position`, `scale` e assim por diante. +
          3. +
        + +

        Objeto e matrizes mundo (world matrices)

        +

        + A [page:Object3D.matrix matriz] (matrix) de um objeto armazena a transformação do objeto relativa ao objeto [page:Object3D.parent pai] (parent); para obter a transformação do objeto em coordenadas mundo, deve-se acessar a [page:Object3D.matrixWorld] do objeto. +

        +

        + Quando a transformação do objeto pai ou filho muda, você pode solicitar que a [page:Object3D.matrixWorld matrixWorld] do objeto filho seja atualizada chamando [page:Object3D.updateMatrixWorld updateMatrixWorld](). +

        + +

        Rotação e Quaternion

        +

        + Three.js fornece duas maneiras de representar rotações 3D: [page:Euler Euler angles] e [page:Quaternion Quaternions], bem como métodos para converter entre os dois. + Os ângulos de Euler estão sujeitos a um problema chamado "gimbal lock", onde certas configurações podem perder um grau de liberdade (impedindo que o objeto seja girado em torno de um eixo). Por esta razão, + as rotações do objeto são sempre armazenadas no objeto [page:Object3D.quaternion quaternion]. +

        +

        + As versões anteriores da biblioteca incluíam uma propriedade `useQuaternion` que, quando definida como false, faria com que a [page:Object3D.matrix matrix] do objeto fosse calculada a partir de um ângulo de Euler. Essa prática está obsoleta --- em vez disso, você deve usar o método [page:Object3D.setRotationFromEuler setRotationFromEuler], que atualizará o quaternion. +

        Чтобы на самом деле иметь возможность отображать что-либо с three.js, Нам нужны три вещи: сцена, камера и средство визуализации, чтобы мы могли визуализировать сцену с помощью камеры.

        + + + const scene = new THREE.Scene(); + const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 ); + + const renderer = new THREE.WebGLRenderer(); + renderer.setSize( window.innerWidth, window.innerHeight ); + document.body.appendChild( renderer.domElement ); + + +

        Давайте воспользуемся моментом, чтобы объяснить, что здесь происходит. Теперь мы настроили сцену, нашу камеру и средство визуализации.

        + +

        Есть несколько разных камер в three.js . А пока давайте воспользуемся `PerspectiveCamera`.

        +

        Первый атрибут - это `поле зрения (field of view)`. FOV - это масштаб сцены, которая видна на дисплее в любой данный момент. Значение указано в градусах.

        + +

        Второй - это `соотношение сторон (aspect ratio)`. Вы почти всегда хотите использовать ширину элемента, деленную на высоту, иначе вы получите тот же результат, что и при воспроизведении старых фильмов на широкоэкранном телевизоре - изображение выглядит сплющенным.

        + +

        Следующие два атрибута - это `ближняя (near)` и `дальняя (far)` плоскость отсечения. Это означает, что объекты, находящиеся дальше от камеры, чем значение `far`, или ближе, чем `near`, не будут отображаться. Сейчас вам не нужно беспокоиться об этом, но вы можете использовать другие значения в своих приложениях, чтобы повысить производительность.

        + +

        Далее следует средство визуализации. Вот тут-то и происходит волшебство. В дополнение к средству визуализации WebGL, которое мы используем здесь, three.js поставляется с несколькими другими, часто используемыми в качестве резервных для пользователей со старыми браузерами или для тех, у кого по какой-либо причине нет поддержки WebGL.

        +

        В дополнение к созданию экземпляра средства визуализации нам также необходимо установить размер, в котором мы хотим, чтобы оно отображало наше приложение. Рекомендуется использовать ширину и высоту области, которую мы хотим заполнить с помощью нашего приложения - в данном случае ширину и высоту окна браузера. Для приложений с высокой производительностью вы также можете задать `setSize` меньшее значения, например `window.innerWidth/2` и `window.innerHeight/2`, что приведет к рендерингу приложения в четверть размера.

        +

        Если вы хотите сохранить размер своего приложения, но отобразить его с меньшим разрешением, вы можете сделать это, вызвав `setSize` с `updateStyle`(третий аргумент) равному false. Например, `setSize(window.innerWidth/2, window.innerHeight/2, false)` будет отображать ваше приложение с половинным разрешением, учитывая, что ваш <canvas > имеет 100% ширины и высоты.

        + +

        И последнее, но не менее важное: мы добавляем элемент `renderer` в наш HTML-документ. Это элемент <canvas>, который рендерер использует для отображения сцены для нас.

        +

        "Все это хорошо, но, где тот кубик, который Вы так обещали?" Давайте добавим его сейчас.

        + + + const geometry = new THREE.BoxGeometry( 1, 1, 1 ); + const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } ); + const cube = new THREE.Mesh( geometry, material ); + scene.add( cube ); + + camera.position.z = 5; + + +

        Чтобы создать куб, нам нужна `BoxGeometry`. Это объект, который содержит все точки (`vertices/вершины`) и заливку (`faces/грани`) куба. Мы подробнее рассмотрим это в будущем.

        + +

        В дополнение к геометрии нам нужен материал, чтобы раскрасить его. Three.js поставляется с несколькими материалами, но пока мы будем придерживаться `MeshBasicMaterial`. Все материалы приобретают объект свойств, которые будут к ним применены. Чтобы все было очень просто, мы предоставляем только атрибут цвета `0x00ff00`, который является зеленым. Это работает так же, как цвета работают в CSS или Photoshop (`шестнадцатеричные цвета/hex colors`).

        + +

        Третья вещь, которая нам нужна, - это `Mesh(Сетка)`. Сетка - это объект, который принимает геометрию и применяет к ней материал, который затем мы можем вставить в нашу сцену и свободно перемещать по ней.

        + +

        По умолчанию, когда мы вызываем `scene.add()`, то, что мы добавляем, будет добавлено к координатам `(0,0,0)`. Это привело бы к тому, что и камера, и куб оказались бы внутри друг друга. Чтобы избежать этого, мы просто немного выдвигаем камеру.

        + +

        Рендеринг сцены

        + +

        Если бы вы скопировали приведенный выше код в HTML-файл, который мы создали ранее, вы бы ничего не смогли увидеть. Это потому, что на самом деле мы еще ничего не рендерим. Для этого нам нужно то, что называется `цикл рендеринга или анимации`.

        + + + function animate() { + requestAnimationFrame( animate ); + renderer.render( scene, camera ); + } + animate(); + + +

        Это создаст цикл, который заставляет средство визуализации отрисовывать сцену каждый раз при обновлении экрана (на обычном экране это означает 60 раз в секунду). Если вы новичок в написании игр в браузере, вы можете сказать "Почему бы нам просто не создать setInterval?" Дело в том, что мы могли бы, но `requestAnimationFrame` имеет ряд преимуществ. Возможно, самым важным из них является то, что он приостанавливается, когда пользователь переходит на другую вкладку браузера, следовательно, не тратя впустую свою драгоценную вычислительную мощность и время автономной работы.

        + +

        Анимация куба

        + +

        Если вы вставите весь приведенный выше код в файл, который вы создали до того, как мы начали, вы должны увидеть зеленое поле. Давайте сделаем все это немного интереснее, повернув его.

        + +

        Добавьте следующий код прямо над вызовом `renderer.render` в вашей функции `animate`:

        + + + cube.rotation.x += 0.01; + cube.rotation.y += 0.01; + + +

        Это будет выполняться каждый кадр (обычно 60 раз в секунду) и придаст кубу приятную анимацию вращения. По сути, все, что вы хотите переместить или изменить во время работы приложения, должно пройти через цикл анимации. Конечно, вы можете вызывать оттуда другие функции, чтобы в итоге не получить `анимированную` функцию, состоящую из сотен строк.

        + +

        Результат

        + +

        Поздравляю! Теперь вы завершили свой первый three.js применение. Это просто, но вы должны с чего-то начать.

        Создание текста ([name])

        +
        +

        + Часто бывают случаи, когда вам может понадобиться использовать текст в вашем three.js приложение - вот + несколько способов, как это сделать. +

        +
        + +

        1. DOM + CSS

        +
        +

        + Использование HTML, как правило, является самым простым и быстрым способом добавления текста. Этот метод + используется для наложения текста в большинстве three.js приложений. +

        +

        Вы можете добавлять содержимое в

        + <div id="info">Описание</div> + +

        + и использовать разметку CSS для абсолютного позиционирования над всеми остальным с + z-index, особенно если вы используете полноэкранный режим three.js. +

        + + +#info { + position: absolute; + top: 10px; + width: 100%; + text-align: center; + z-index: 100; + display:block; +} + + +
        + + +

        2. Использование [page:CSS2DRenderer] или [page:CSS3DRenderer]

        +
        +

        + Используйте эти рендереры для отрисовки высококачественного текста, содержащегося в элементах DOM, в вашу сцену three.js. + Это похоже на 1. за исключением того, что с помощью этих средств визуализации элементы могут быть более тесно и динамично интегрированы в сцену. +

        +
        + + +

        3. Нарисуйте текст на холсте используя [page:Texture]

        +
        +

        Используйте этот способ, если вы хотите легко нарисовать текст на плоскости в вашем three.js сцене.

        +
        + + +

        4. Создайте модель в вашем любимом 3D-приложении и экспортируйте в three.js

        +
        +

        Используйте этот способ, если вы предпочитаете работать со своими 3d-приложениями и импортировать модели в three.js .

        +
        + + +

        5. Процедурная геометрия текста

        +
        +

        + Если вы предпочитаете работать исключительно в three.js или создавать процедурные и динамические 3D + текстовые геометрии, вы можете создать mesh, геометрия которой является экземпляром THREE.TextGeometry: +

        +

        + new THREE.TextGeometry( text, parameters ); +

        +

        + Однако для того, чтобы это сработало, вашей текстовой геометрии потребуется экземпляр из THREE.Font + должен быть установлен в его параметре "шрифт". + + Смотрите страницу [page:TextGeometry] для получения дополнительной информации о том, как это можно сделать, описания каждого + принимаемого параметра и список шрифтов JSON, которые поставляются с THREE.js. +

        + +

        Примеры

        + +

        + [example:webgl_geometry_text WebGL / geometry / text]
        + [example:webgl_shadowmap WebGL / shadowmap] +

        + +

        + Если шрифт не работает или вы хотите использовать шрифт, которого там нет, есть учебное пособие по + скрипту python для blender, который позволит экспортировать текст в Three.js в формате JSON: + [link:http://www.jaanga.com/2012/03/blender-to-threejs-create-3d-text-with.html] +

        + +
        + + +

        6. Растровые шрифты

        +
        +

        + Растровые шрифты (bitmap fonts) позволяют группировать глифы в единую BufferGeometry. Рендеринг BMFont + поддерживает перенос слов, межбуквенный интервал, кернинг, поля расстояния со знаком со стандартными + производными, многоканальные поля расстояния со знаком, шрифты с несколькими текстурами и многое другое. + Смотрите [link:https://github.com/felixmariotto/three-mesh-ui three-mesh-ui] или [link:https://github.com/Jam3/three-bmfont-text three-bmfont-text]. +

        +

        + Стандартные шрифты доступны в таких проектах, как + [link:https://github.com/etiennepinchon/aframe-fonts A-Frame Fonts], или вы можете создать свой собственный + из любого .TTF шрифта, оптимизированный для включения только символов, необходимых для проекта. +

        +

        + Некоторые полезные инструменты: +

          • +
        +
        + + +

        7. Текст Тройка (Troika Text)

        +
        +

        + Пакет [link:https://www.npmjs.com/package/troika-three-text troika-three-text] отображает + качественный сглаженный текст, использующий ту же технику, что и BMFonts, но работающий напрямую с любым .TTF + или .WOFF файлом шрифта, чтобы вам не приходилось восстанавливать текстуру глифа в автономном режиме. Он также добавляет + возможности, в том числе: +

        +
          +
        • Такие эффекты, как штрихи, отбрасываемые тени и кривизна
          • +

        Рисование линий ([name])

        +
        +

        + Допустим, вы хотите нарисовать линию или круг, а не каркас [page:Mesh]. + Сначала нам нужно настроить [page:WebGLRenderer renderer](рендеринг), [page:Scene scene](сцену) и камеру (см. страницу Создания сцены). +

        + +

        Вот код, который мы будем использовать:

        + +const renderer = new THREE.WebGLRenderer(); +renderer.setSize( window.innerWidth, window.innerHeight ); +document.body.appendChild( renderer.domElement ); + +const camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 500 ); +camera.position.set( 0, 0, 100 ); +camera.lookAt( 0, 0, 0 ); + +const scene = new THREE.Scene(); + +

        Следующее, что мы сделаем, - это определим материал. Для линий мы должны использовать [page:LineBasicMaterial] или [page:LineDashedMaterial].

        + +// создаем синий LineBasicMaterial +const material = new THREE.LineBasicMaterial( { color: 0x0000ff } ); + + +

        + После материала нам понадобится геометрия с некоторыми вершинами: +

        + + +const points = []; +points.push( new THREE.Vector3( - 10, 0, 0 ) ); +points.push( new THREE.Vector3( 0, 10, 0 ) ); +points.push( new THREE.Vector3( 10, 0, 0 ) ); + +const geometry = new THREE.BufferGeometry().setFromPoints( points ); + + +

        Обратите внимание, что линии рисуются между каждой последовательной парой вершин, но не между первой и последней (линия не замкнута).

        + +

        Теперь, когда у нас есть точки для двух линий и материал, мы можем соединить их вместе, чтобы сформировать линию.

        + +const line = new THREE.Line( geometry, material ); + +

        Все, что осталось, это добавить его в сцену и вызвать [page:WebGLRenderer.render render].

        + + +scene.add( line ); +renderer.render( scene, camera ); + + +

        Теперь вы должны увидеть стрелку, направленную вверх, сделанную из двух синих линий.

        Часто задаваемые вопросы [name]

        + +

        Какой формат 3D-модели лучше всего поддерживается?

        +
        +

        + Рекомендуемый формат для импорта и экспорта - golf (формат передачи GL). Поскольку glTF ориентирован на доставку ресурсов во время выполнения, он компактен для передачи и быстр для загрузки. +

        +

        + three.js предоставляет загрузчики для многих других популярных форматов, таких как FBX, Collada или OBJ. Тем не менее, вы всегда должны сначала пытаться настроить рабочий процесс на основе glTF в своих проектах. Для получения дополнительной информации см. [link:#manual/introduction/Loading-3D-models loading 3D models] (загрузка 3D-моделей). +

        +
        + +

        Почему в примерах присутствуют теги meta viewport?

        +
        + <meta name="viewport" content="width=device-width, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0"> + +

        + Эти теги управляют размером и масштабом областью просмотра экрана для мобильных браузеров (где содержимое страницы может отображаться с размером, отличным от видимой области просмотра экрана). +

        + +

        +
        + +

        Как можно сохранить масштаб сцены при изменении размера?

        +

        + Мы хотим, чтобы все объекты, независимо от их расстояния от камеры, отображались одинакового размера, даже при изменении размера окна. + + Ключевым уравнением для решения этой проблемы является следующая формула для видимой высоты на заданном расстоянии: + + +visible_height = 2 * Math.tan( ( Math.PI / 180 ) * camera.fov / 2 ) * distance_from_camera; + + Если мы увеличим высоту окна на определенный процент, то мы хотим, чтобы видимая высота на всех расстояниях + увеличилась на тот же процент. Этого нельзя сделать, просто изменив положение камеры. + Вместо этого вы должны изменить поле зрения камеры. + [link:http://jsfiddle.net/Q4Jpu/ Example] (пример). +

        + +

        Почему часть моего объекта невидима?

        +

        + Это может быть связано с определением граней. Грани имеют ориентацию, которая определяет, + какая сторона является какой. И определение удаляет заднюю часть при нормальных условиях. + Чтобы увидеть, это ли ваша проблема, измените сторону материала на THREE.DoubleSide. + material.side = THREE.DoubleSide +

        + +

        Почему three.js иногда возвращает странные результаты для недопустимых входных данных?

        +

        + Из соображений производительности в большинстве случаев three.js не проверяет входные данные. Ваше приложение должно убедиться, что все входные данные действительны. +

        +

        Если у вас установлен Ruby, вы можете получить тот же результат, выполнив:

        + + ruby -r webrick -e "s = WEBrick::HTTPServer.new(:Port => 8000, :DocumentRoot => Dir.pwd); trap('INT') { s.shutdown }; s.start" + +
        + +

        PHP сервер

        +
        +

        PHP также имеет встроенный веб-сервер, начиная с php 5.4.0:

        + php -S localhost:8000 +
        + +

        Lighttpd

        +
        +

        + Lighttpd - это очень легкий веб-сервер общего назначения. Мы рассмотрим установку его на OSX с помощью + HomeBrew. В отличие от других серверов, обсуждаемых здесь, lighttpd является полноценным прод. сервером. +

        + +
          +
        1. + Установка с помощью homebrew + brew install lighttpd +
          2. +
        2. + Создайте конфигурационный файл с именем lighttpd.conf в каталоге, в котором вы хотите запустить + ваш веб-сервер. Пример [link:http://redmine.lighttpd.net/projects/lighttpd/wiki/TutorialConfiguration + here]. +
          3. +
        3. + В файле conf измените корневой каталог server.document на каталог, из которого вы хотите обслуживать + файлы. +
          4. +
        4. + Запуск + lighttpd -f lighttpd.conf +
          5. +
        5. + Перейдите в http://localhost:3000/ и он будет обслуживать статические файлы из каталога, который вы + выбрали. +
          6. +
        +
        +

        IIS

        +
        +

        Если вы используете Microsoft IIS в качестве веб-сервера. Пожалуйста, добавьте настройки типа MIME для + расширения .fbx перед загрузкой.

        + File name extension: fbx MIME Type: text/plain +

        По умолчанию IIS блокирует загрузку файлов .fbx, .obj. Вы должны настроить IIS, чтобы такие файлы можно было + загружать.

        Установка ([name])

        + +

        + Вы можете установить three.js с помощью [link:https://www.npmjs.com/ npm] и современных инструментов сборки или + быстро начните работу со статического хостинга или CDN. Для большинства пользователей установка из npm является + лучшим выбором. +

        + +

        + Что бы вы ни выбрали, будьте последовательны и импортируйте все файлы из одной и той же версии библиотеки. + Смешивание файлов из разных источников может привести к включению дублирующегося кода или даже к неожиданной + поломке + приложения. +

        + + +

        + Все способы установки three.js зависят от модулей ES (см. + [link:https://eloquentjavascript.net/10_modules.html#h_hF2FmOVxw7 Eloquent JavaScript: ECMAScript Modules]), + которые + позволяют включать в конечный проект только те части библиотеки, которые необходимы. +

        + +

        Установка из npm

        + +

        + Чтобы установить [link:https://www.npmjs.com/package/three three] модуль npm, откройте окно терминала в папке + вашего + проекта и запустите: +

        + + + npm install three + + +

        + Пакет будет загружен и установлен. Когда вы будете готовы импортировать его в свой код: +

        + + + // Вариант 1: Импортируйте весь three.js основная библиотека. + import * as THREE from 'three'; + + const scene = new THREE.Scene(); + + + // Вариант 2: Импортируйте только те детали, которые вам нужны. + import { Scene } from 'three'; + + const scene = new Scene(); + + +

        + При установке из npm вы почти всегда будете использовать какой-либо + [link:https://eloquentjavascript.net/10_modules.html#h_zWTXAU93DC bundling tool], чтобы объединить все пакеты, + необходимые вашему проекту, в один файл JavaScript. В то время как любой современный пакет JavaScript можно + использовать с three.js , самым популярным выбором является [link:https://webpack.js.org/ webpack]. +

        + +

        + Не ко всем функциям можно получить доступ непосредственно через модуль three (также называемый "голым + импортом"). Другие популярные части библиотеки, такие как элементы управления, загрузчики и эффекты + постобработки, + должны быть импортированы из подпапки [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm + examples/jsm]. + Чтобы узнать больше, смотрите Примеры ниже. +

        + +

        + Узнайте больше о модулях npm по ссылке [link:https://eloquentjavascript.net/20_node.html#h_J6hW/SmL/a Eloquent + JavaScript: Installing with npm](Выразительный JavaScript: Установка с помощью npm). +

        + +

        Установка с CDN или статического хостинга

        + +

        + В three.js библиотеку можно использовать без какой-либо системы сборки, либо загрузив файлы на свой собственный + веб-сервер, либо используя существующий CDN. Поскольку библиотека полагается на модули ES, любой скрипт, который + ссылается на нее, должен использовать type="module", как показано ниже. + Также требуется определить карту импорта, которая разрешает пустой модуль, указанный как `three`. +

        + + + <script async src="https://unpkg.com/es-module-shims@1.3.6/dist/es-module-shims.js"></script> + + <script type="importmap"> + { + "imports": { + "three": "https://unpkg.com/three@<version>/build/three.module.js" + } + } + </script> + + <script type="module"> + + import * as THREE from 'three'; + + const scene = new THREE.Scene(); + + </script> + + +

        + Поскольку импорт карт еще не поддерживается всеми браузерами, необходимо добавить полифил *es-module-shims.js*. +

        + +

        Дополнения

        + +

        + Ядро three.js сосредоточен на наиболее важных компонентах 3D-движка. Многие другие полезные компоненты, такие + как элементы управления, загрузчики и эффекты постобработки, являются частью каталога + [link:https://github.com/mrdoob/three.js/tree/dev/examples/jsm examples/jsm]. Они называются "дополнениями"(addons) (ранее назывались "примерами"(examples)), + потому что, хотя вы можете использовать их в готовом виде, они также предназначены для ремиксов и кастомизации. + Эти компоненты всегда синхронизируются с основной библиотекой, в то время как аналогичные пакеты сторонних + разработчиков в npm поддерживаются разными пользователями и могут быть устаревшими. +

        + +

        + Дополнения не нужно устанавливать отдельно, но их нужно импортировать отдельно. Если three.js был + установлен с помощью npm, вы можете загрузить компонент [page:OrbitControls](Управление орбитой) с помощью: +

        + + + + import { OrbitControls } from 'three/addons/controls/OrbitControls.js'; + + const controls = new OrbitControls( camera, renderer.domElement ); + + +

        + Если three.js был установлен с CDN, используйте тот же код, но с `three/addons/` в карте импорта. +

        + + + <script async src="https://unpkg.com/es-module-shims@1.3.6/dist/es-module-shims.js"></script> + + <script type="importmap"> + { + "imports": { + "three": "https://unpkg.com/three@<version>/build/three.module.js", + "three/addons/": "https://unpkg.com/three@<version>/examples/jsm/" + } + } + </script> + <script type="module"> + + import * as THREE from 'three'; + import { OrbitControls } from 'three/addons/controls/OrbitControls.js'; + + const controls = new OrbitControls( camera, renderer.domElement ); + + </script> + + +

        + Важно, чтобы все файлы использовали одну и ту же версию. Не импортируйте разные дополнения(addons) из разных версий и + не используйте дополнения(addons) из версии, отличной от three.js самой библиотека. +

        + +

        Совместимость

        + +

        CommonJS импорт

        + +

        + В то время как большинство современных пакетов JavaScript теперь поддерживают модули по умолчанию, некоторые + старые + инструменты сборки могут этого не делать. В этих случаях вы, вероятно, можете настроить пакет для подключения + модулей ES: [link:http://browserify.org/ Browserify] просто нужен плагин [link:https://github.com/babel/babelify babelify] , как пример. + +

        + +

        Node.js

        + +

        + Так как three.js создан для Интернета, он зависит от браузера и DOM API, которые не всегда существуют в Node.js. + Некоторые из этих проблем могут быть решены с помощью прослоек, таких как + [link:https://github.com/stackgl/headless-gl headless-gl], или путем замены компонентов, таких как + [page:TextureLoader], пользовательскими альтернативами. Другие API-интерфейсы DOM могут быть глубоко переплетены + с использующим их кодом, и обойти их будет сложнее. + Мы приветствуем простые и поддерживаемые предложения `pull requests` для улучшения поддержки Node.js, но + рекомендуем сначала открыть `issue`(вопрос), чтобы обсудить ваши улучшения. +

        + +

        + Обязательно добавьте `{ "type": "module" }` в свой `package.json`, чтобы включить модули ES6 в ваш проект. +

        Загрузка 3D-моделей ([name])

        + +

        + 3D-модели доступны в сотнях форматов, каждый из которых имеет различные + цели, разнообразные функции и различную сложность. Хотя three.js предоставляет множество + + загрузчиков, выбор правильного формата и + рабочего процесса сэкономит время и не разочарует в дальнейшем. С некоторыми форматами + сложно работать, они неэффективны для работы в реальном времени или просто не + поддерживаются в полной мере в настоящее время. +

        + +

        + В этом руководстве представлен рабочий процесс, рекомендуемый для большинства пользователей, и рекомендации + о том, что предпринять, если что-то пойдет не так, как ожидалось. +

        + +

        + +

        + Если вы новичок в управлении локальным сервером, начните с раздела + [link:#manual/introduction/How-to-run-things-locally how to run things locally] (Локальная разработка). + Многих распространенных ошибок при просмотре 3D-моделей можно избежать, правильно разместив файлы. +

        + +

        Прежде чем начать

        + +

        + Там, где это возможно, мы рекомендуем использовать glTF (GL Transmission Format). Оба + .GLB и .GLTF версии формата + хорошо поддерживаются. Поскольку glTF ориентирован на доставку ресурсов во время выполнения, он + компактен для передачи и быстр для загрузки. Объекты включают в себя mesh, материалы, + текстуры, скины, скелеты, цели морфинга, анимацию, освещение и + камеры. +

        + +

        + Файлы glTF, находящиеся в открытом доступе, доступны на таких сайтах, как + + Sketchfab, так же есть различные инструменты включающие экспорт glTF: +

        + + + +

        + Если предпочитаемые вами инструменты не поддерживают glTF, рассмотрите возможность запроса экспорта glTF у авторов или опубликуйте + в ветке glTF roadmap. +

        + +

        + Если glTF не подходит, используйте популярные форматы, такие как FBX, OBJ или COLLADA + также доступны и регулярно обновляются. +

        + +

        Loading

        + +

        + Только несколько загрузчиков (например, [page:ObjectLoader]) включены по умолчанию с + three.js — другие должны быть добавлены в ваше приложение индивидуально. +

        + + + import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'; + + +

        + После того, как вы импортировали загрузчик, вы готовы добавить модель в свою сцену. Синтаксис отличается у + разных загрузчиков — при использовании другого формата ознакомьтесь с примерами и документацией для этого + загрузчика. Для glTF использование с глобальными скриптами было бы: +

        + + + const loader = new GLTFLoader(); + + loader.load( 'path/to/model.glb', function ( gltf ) { + + scene.add( gltf.scene ); + + }, undefined, function ( error ) { + + console.error( error ); + + } ); + + +

        + См. [page:GLTFLoader GLTFLoader documentation] для получения более подробной информации. +

        + +

        Диагностика

        + +

        + Вы потратили часы на создание шедевра ручной работы, загружаете его на + веб—страницу и - о нет! 😭 Он искажен, неправильно окрашен или полностью отсутствует. + Начните с выполнения следующих действий по устранению неполадок: +

        + +
          +
        1. + Проверьте консоль JavaScript на наличие ошибок и убедитесь, что вы использовали + обратный вызов `onError` при вызове `.load()` для регистрации результата. +
          2. +
        2. + Просмотрите модель в другом приложении. Для glTF, средства просмотра с помощью перетаскивания + доступны для + three.js и + babylon.js. Если модель + отображается правильно в одном или нескольких приложениях, + сообщить об ошибке в three.js. + Если модель не может быть показана ни в одном приложении, мы настоятельно рекомендуем предоставить приложение + (можно в песочнице) для воспроизведения бага. +
          3. +
        3. + Попробуйте увеличить или уменьшить масштаб модели в 1000 раз. Многие модели + масштабируются по-разному, и большие модели могут не отображаться, если камера находится + внутри модели. +
          4. +
        4. + Попробуйте добавить и расположить источник света. Модель может быть скрыта в темноте. +
          5. +
        5. + Ищите неудачные запросы текстур на вкладке сеть, например + `"C:\\Path\To\Model\texture.jpg "`. Вместо этого используйте пути относительно вашей + модели, например `images/texture.jpg ` — для этого может потребоваться + редактирование файла модели в текстовом редакторе. +
          6. +
        + +

        Помощь

        + +

        + Если вы прошли шаги описанные выше для устранения неполадок, а ваша модель + по-прежнему не работает, правильный подход это обращение за помощью которое поможет вам + быстрее найти решение. Разместите вопрос на + форуме three.js и, по возможности, + приложите свою модель (или более простую модель с той же проблемой) в любых + доступных вам форматах. Предоставьте достаточно информации, чтобы кто-то другой мог воспроизвести + проблему быстро — в идеале, живая демонстрация. +

        - -

        - 首先， three.js 是为 web 而构建的，其依赖于浏览器，以及并不总是存在于 Node.js 中的 DOM API。其中的一些问题可使用类似 [link:https://github.com/stackgl/headless-gl headless-gl] 的 shim ，或使用定制的替代品来替换掉一些组件（例如 [page:TextureLoader] ）来进行解决。其他的 DOM API 或许和使用它们的代码紧密相连在一起，并且很难解决。我们欢迎简单且可维护的 pull request，以改善对 Node.js 的支持。但建议您首先提出一个 issue 来讨论您的改进。 + Because three.js is built for the web, it depends on browser and DOM APIs that don't always exist in Node.js. Some of these issues can be resolved by using shims like [link:https://github.com/stackgl/headless-gl headless-gl], or by replacing components like [page:TextureLoader] with custom alternatives. Other DOM APIs may be deeply intertwined with the code that uses them, and will be harder to work around. We welcome simple and maintainable pull requests to improve Node.js support, but recommend opening an issue to discuss your improvements first.

        - 第二，Node.js 对于 ES module 的支持可以说……很复杂。在 Node.js v12 中， three.js 的核心库可使用 require('three') 来作为 CommonJS module 进行导入。然而，大多数在 examples/jsm 中的示例组件并不能够这样。未来版本的 Node.js 或许可以解决这个问题，但同时你可能需要一些类似 [link:https://github.com/standard-things/esm esm] 的解决方案，来使得你的 Node.js 应用程序识别 ES module。 + Make sure to add `{ "type": "module" }` to your `package.json` to enable ES6 modules in your node project.

They can be changed but the ray will change its form abruptly: - * - * @param {boolean} isEternal If true the ray never extinguishes. Otherwise its life is controlled by the 'birthTime' and 'deathTime' parameters. Default: true if any of those two parameters is undefined. - * - * @param {double} birthTime The time at which the ray starts its life and begins propagating. Only if isEternal is false. Default: None. - * - * @param {double} deathTime The time at which the ray ends vanishing and its life. Only if isEternal is false. Default: None. - * - * @param {double} propagationTimeFactor From 0 to 1. Lifetime factor at which the ray ends propagating and enters the steady phase. For example, 0.1 means it is propagating 1/10 of its lifetime. Default: 0.1 - * - * @param {double} vanishingTimeFactor From 0 to 1. Lifetime factor at which the ray ends the steady phase and begins vanishing. For example, 0.9 means it is vanishing 1/10 of its lifetime. Default: 0.9 - * - * @param {double} subrayPeriod Subrays cycle periodically. This is their time period. Default: 4 - * - * @param {double} subrayDutyCycle From 0 to 1. This is the fraction of time a subray is active. Default: 0.6 - * - * - * These parameters cannot change after lightning creation: - * - * @param {integer} maxIterations: Greater than 0. The number of ray's leaf segments is 2**maxIterations. Default: 9 - * - * @param {boolean} isStatic Set to true only for rays which won't change over time and are not attached to moving objects (Rare case). It is used to set the vertex buffers non-dynamic. You can omit calling update() for these rays. - * - * @param {integer} ramification Greater than 0. Maximum number of child subrays a subray can have. Default: 5 - * - * @param {integer} maxSubrayRecursion Greater than 0. Maximum level of recursion (subray descendant generations). Default: 3 - * - * @param {double} recursionProbability From 0 to 1. The lower the value, the less chance each new generation of subrays has to generate new subrays. Default: 0.6 - * - * @param {boolean} generateUVs If true, the ray geometry will have uv coordinates generated. u runs along the ray, and v across its perimeter. Default: false. - * - * @param {Object} randomGenerator Set here your random number generator which will seed the THREE.SimplexNoise and other decisions during ray tree creation. - * It can be used to generate repeatable rays. For that, set also the noiseSeed parameter, and each ray created with that generator and seed pair will be identical in time. - * The randomGenerator parameter should be an object with a random() function similar to Math.random, but seedable. - * It must have also a getSeed() method, which returns the current seed, and a setSeed( seed ) method, which accepts as seed a fractional number from 0 to 1, as well as any other number. - * The default value is an internal generator for some uses and Math.random for others (It is non-repeatable even if noiseSeed is supplied) - * - * @param {double} noiseSeed Seed used to make repeatable rays (see the randomGenerator) - * - * @param {function} onDecideSubrayCreation Set this to change the callback which decides subray creation. You can look at the default callback in the code (createDefaultSubrayCreationCallbacks)for more info. - * - * @param {function} onSubrayCreation This is another callback, more simple than the previous one. It can be used to adapt the form of subrays or other parameters once a subray has been created and initialized. It is used in the examples to adapt subrays to a sphere or to a plane. - * - * -*/ - - class LightningStrike extends THREE.BufferGeometry { - - constructor( rayParameters = {} ) { - - super(); - this.isLightningStrike = true; - this.type = 'LightningStrike'; // Set parameters, and set undefined parameters to default values - - this.init( LightningStrike.copyParameters( rayParameters, rayParameters ) ); // Creates and populates the mesh - - this.createMesh(); - - } - - static createRandomGenerator() { - - const numSeeds = 2053; - const seeds = []; - - for ( let i = 0; i < numSeeds; i ++ ) { - - seeds.push( Math.random() ); - - } - - const generator = { - currentSeed: 0, - random: function () { - - const value = seeds[ generator.currentSeed ]; - generator.currentSeed = ( generator.currentSeed + 1 ) % numSeeds; - return value; - - }, - getSeed: function () { - - return generator.currentSeed / numSeeds; - - }, - setSeed: function ( seed ) { - - generator.currentSeed = Math.floor( seed * numSeeds ) % numSeeds; - - } - }; - return generator; - - } - - static copyParameters( dest = {}, source = {} ) { - - const vecCopy = function ( v ) { - - if ( source === dest ) { - - return v; - - } else { - - return v.clone(); - - } - - }; - - dest.sourceOffset = source.sourceOffset !== undefined ? vecCopy( source.sourceOffset ) : new THREE.Vector3( 0, 100, 0 ), dest.destOffset = source.destOffset !== undefined ? vecCopy( source.destOffset ) : new THREE.Vector3( 0, 0, 0 ), dest.timeScale = source.timeScale !== undefined ? source.timeScale : 1, dest.roughness = source.roughness !== undefined ? source.roughness : 0.9, dest.straightness = source.straightness !== undefined ? source.straightness : 0.7, dest.up0 = source.up0 !== undefined ? vecCopy( source.up0 ) : new THREE.Vector3( 0, 0, 1 ); - dest.up1 = source.up1 !== undefined ? vecCopy( source.up1 ) : new THREE.Vector3( 0, 0, 1 ), dest.radius0 = source.radius0 !== undefined ? source.radius0 : 1, dest.radius1 = source.radius1 !== undefined ? source.radius1 : 1, dest.radius0Factor = source.radius0Factor !== undefined ? source.radius0Factor : 0.5, dest.radius1Factor = source.radius1Factor !== undefined ? source.radius1Factor : 0.2, dest.minRadius = source.minRadius !== undefined ? source.minRadius : 0.2, // These parameters should not be changed after lightning creation.

          Aligning HTML Elements to 3D

          Let's start simple. We'll make a 3D scene with a few primitives and then add a label to each primitive. We'll start with an example from the article on responsive pages

          We'll add some OrbitControls like we did in the article on lighting.

-NOTE! This article is deprecated. Three.js r125
-removed support for Geometry. Please refer to
-the article on custom BufferGeometry.
-
          
-
-
          A previous article gave a tour of
-the various built in primitives included in THREE.js. In this
-article we'll cover making our own geometry.
          
-
          Just to be clear, if you are serious about making 3D content,
-the most common way is to use a 3D modeling package like
-Blender,
-Maya,
-3D Studio Max,
-Cinema4D, etc...
-You'd build a model and then export to gLTF
-or .obj and load them up.
-Whichever one you choose, expect to spend 2 or 3 weeks going through
-their respective tutorials as all of them have a learning curve
-to be useful.
          
-
          Still, there are times when we might want to generate our own
-3D geometry in code instead of using a modeling package.
          
-
          First let's just make a cube. Even though three.js already
-provides us with BoxGeometry and BoxGeometry a
-cube is easy to understand so let's start there.
          
-
          There are 2 ways to make custom geometry in THREE.js. One
-is with the Geometry class, the other is BufferGeometry.
-Each has their advantages. Geometry is arguably easier to
-use but slower and uses more memory. For few 1000s triangles
-it's a great choice but for 10s of thousands of triangles
-it might be better to use BufferGeometry.
          
-
          BufferGeometry is arguably harder to use but uses less
-memory and is faster. If quick rule of thumb might be
-if you're going to generate more than 10000 triangles
-consider using BufferGeometry.
          
-
          Note when I say Geometry is slower I mean it is slower to
-start and slower to modify but it is not slower to draw so
-if you're not planning on modifying your geometry then
-as long as it's not too large there will only be slightly more
-delay for your program to start using Geometry vs using
-BufferGeometry. We'll go over both eventually. For now
-though let's use geometry as it's easier to understand IMO.
          
-
          First let's make a cube with Geometry. We'll start
-with an example from the article on responsiveness.
          
-
          Let's remove the part that uses BoxGeometry and replace it with
-a Geometry.
          
-
          -const boxWidth = 1;
--const boxHeight = 1;
--const boxDepth = 1;
--const geometry = new THREE.BoxGeometry(boxWidth, boxHeight, boxDepth);
-+const geometry = new THREE.Geometry();
-
          
-
          Now let's add the 8 corners of a cube. Here are the 8 corners.
          
-
          
-
-
          Centered around the origin we can add the vertex positions like this
          
-
          const geometry = new THREE.Geometry();
-+geometry.vertices.push(
-+  new THREE.Vector3(-1, -1,  1),  // 0
-+  new THREE.Vector3( 1, -1,  1),  // 1
-+  new THREE.Vector3(-1,  1,  1),  // 2
-+  new THREE.Vector3( 1,  1,  1),  // 3
-+  new THREE.Vector3(-1, -1, -1),  // 4
-+  new THREE.Vector3( 1, -1, -1),  // 5
-+  new THREE.Vector3(-1,  1, -1),  // 6
-+  new THREE.Vector3( 1,  1, -1),  // 7
-+);
-
          
-
          We then need to make triangles, 2 for each face of the cube
          
-
          
-
-
          We do that by creating Face3 objects and specifying the indices
-of the 3 vertices that make up that face.
          
-
          The order we specify the vertices is important. To be pointing toward the
-outside of the cube they must be specified in a counter clockwise direction
-when that triangle is facing the camera.
          
-
          
-
-
          Following that pattern we can specify the 12 triangles that make
-the cube like this
          
-
          geometry.faces.push(
-  // front
-  new THREE.Face3(0, 3, 2),
-  new THREE.Face3(0, 1, 3),
-  // right
-  new THREE.Face3(1, 7, 3),
-  new THREE.Face3(1, 5, 7),
-  // back
-  new THREE.Face3(5, 6, 7),
-  new THREE.Face3(5, 4, 6),
-  // left
-  new THREE.Face3(4, 2, 6),
-  new THREE.Face3(4, 0, 2),
-  // top
-  new THREE.Face3(2, 7, 6),
-  new THREE.Face3(2, 3, 7),
-  // bottom
-  new THREE.Face3(4, 1, 0),
-  new THREE.Face3(4, 5, 1),
-);
-
          
-
          A few other minor changes to the original code and it should
-work.
          
-
          These cubes are twice as large as the BoxGeometry we were
-using before so let's move the camera back a little
          
-
          const fov = 75;
-const aspect = 2;  // the canvas default
-const near = 0.1;
--const far = 5;
-+const far = 100;
-const camera = new THREE.PerspectiveCamera(fov, aspect, near, far);
--camera.position.z = 2;
-+camera.position.z = 5;
-
          
-
          and let's separate them a little more and I changed their colors just because
          
-
          const cubes = [
--  makeInstance(geometry, 0x44aa88,  0),
--  makeInstance(geometry, 0x8844aa, -2),
--  makeInstance(geometry, 0xaa8844,  2),
-+  makeInstance(geometry, 0x44FF44,  0),
-+  makeInstance(geometry, 0x4444FF, -4),
-+  makeInstance(geometry, 0xFF4444,  4),
-];
-
          
-
          One last thing is we haven't added normals yet so we
-can't do any lighting. Let's change the material
-to something that doesn't need lights.
          
-
          function makeInstance(geometry, color, x) {
--  const material = new THREE.MeshPhongMaterial({color});
-+  const material = new THREE.MeshBasicMaterial({color});
-
-  const cube = new THREE.Mesh(geometry, material);
-  scene.add(cube);
-
-  ...
-
          
-
          and we get cubes we made ourselves.

          We can specify a color per face by setting the color property of
-each face.
          
-
          geometry.faces[ 0].color = geometry.faces[ 1].color = new THREE.Color('red');
-geometry.faces[ 2].color = geometry.faces[ 3].color = new THREE.Color('yellow');
-geometry.faces[ 4].color = geometry.faces[ 5].color = new THREE.Color('green');
-geometry.faces[ 6].color = geometry.faces[ 7].color = new THREE.Color('cyan');
-geometry.faces[ 8].color = geometry.faces[ 9].color = new THREE.Color('blue');
-geometry.faces[10].color = geometry.faces[11].color = new THREE.Color('magenta');
-
          
-
          note we need to tell the material we want to use vertex colors
          
-
          -const material = new THREE.MeshBasicMaterial({color});
-+const material = new THREE.MeshBasicMaterial({vertexColors: true});

-  click here to open in a separate window
-
          
-
-
          
-
          We can instead set the color of each individual vertex by setting the vertexColors
-property of a Face to an array of the 3 colors for the 3 vertices.
          
-
          geometry.faces.forEach((face, ndx) => {
-  face.vertexColors = [
-    (new THREE.Color()).setHSL(ndx / 12      , 1, 0.5),
-    (new THREE.Color()).setHSL(ndx / 12 + 0.1, 1, 0.5),
-    (new THREE.Color()).setHSL(ndx / 12 + 0.2, 1, 0.5),
-  ];
-});
-
          
-
          
-  
          
-  click here to open in a separate window
-
          
-
-
          
-
          To use lighting we need normals. Normals are vectors that specify direction.
-Just like the colors we can specify a normal for the face by setting the normal
-property on each face with
          
-
          face.normal = new THREE.Vector3(...)
-
          
-
          or we can specify a normal for each vertex by setting the vertexNormals
-property with something like
          
-
          face.vertexNormals = [
-  new THREE.Vector3(...),
-  new THREE.Vector3(...),
-  new THREE.Vector3(...),
-]
-
          
-
          but often it's much easier to just ask THREE.js to compute normals
-for us based on the positions we specified.
          
-
          For face normals we'd call Geometry.computeFaceNormals as in
          
-
          geometry.computeFaceNormals();
-
          
-
          Removing the vertex color stuff and changing the material back to MeshPhongMaterial
          
-
          -const material = new THREE.MeshBasicMaterial({vertexColors: true});
-+const material = new THREE.MeshPhongMaterial({color});
-
          
-
          and now our cubes can be lit.

-
          
-
-
          
-
          Using face normals will always give us a faceted look. We can use
-vertex normals for a smoother look by calling Geometry.computeVertexNormals
          
-
          -geometry.computeFaceNormals();
-+geometry.computeVertexNormals();
-
          
-
          Unfortunately a cube is not a good candidate for vertex normals since it
-means each vertex gets its normal from the
-normals of all the faces it shares.

-
-
          
-
          Adding texture coordinates, sometimes called UVs, is done via an array of
-layers of parallel arrays to the faces array which is set via Geometry.faceVertexUvs.
-For our cube we could do something like
          
-
          geometry.faceVertexUvs[0].push(
-  // front
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 1), new THREE.Vector2(0, 1) ],
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 0), new THREE.Vector2(1, 1) ],
-  // right
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 1), new THREE.Vector2(0, 1) ],
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 0), new THREE.Vector2(1, 1) ],
-  // back
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 1), new THREE.Vector2(0, 1) ],
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 0), new THREE.Vector2(1, 1) ],
-  // left
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 1), new THREE.Vector2(0, 1) ],
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 0), new THREE.Vector2(1, 1) ],
-  // top
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 1), new THREE.Vector2(0, 1) ],
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 0), new THREE.Vector2(1, 1) ],
-  // bottom
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 1), new THREE.Vector2(0, 1) ],
-  [ new THREE.Vector2(0, 0), new THREE.Vector2(1, 0), new THREE.Vector2(1, 1) ],
-);
-
          
-
          It's important to notice faceVertexUvs is an array of layers. Each layer
-is another set of UV coordinates. By default there is one layer of UV coordinates,
-layer 0, so we just add our UVs to that layer.
          
-
          Let's add a texture to our material and switch back to compute face normals

          Putting that all together, let's make a simple heightmap based
-terrain mesh.
          
-
          A heightmap based terrain is where you have a 2D array of heights
-that you apply them to a grid. An easy way to get a 2D array of heights
-is to draw them in an image editing program. Here's an image I drew.
-It's 96x64 pixels
          
-
          
-
-
          We'll load that and then generate a heightmap mesh from it.
-We can use the ImageLoader to load the image.
          
-
          const imgLoader = new THREE.ImageLoader();
-imgLoader.load('resources/images/heightmap-96x64.png', createHeightmap);
-
-function createHeightmap(image) {
-  // extract the data from the image by drawing it to a canvas
-  // and calling getImageData
-  const ctx = document.createElement('canvas').getContext('2d');
-  const {width, height} = image;
-  ctx.canvas.width = width;
-  ctx.canvas.height = height;
-  ctx.drawImage(image, 0, 0);
-  const {data} = ctx.getImageData(0, 0, width, height);
-
-  const geometry = new THREE.Geometry();
-
          
-
          We extracted the data from the image, now we'll make a grid of cells.
-The cells are the squares formed by the center points of each pixel
-from the image
          
-
          
-
-
          For each cell we'll generate 5 vertices. One for each corner of the cell
-and one at the center point of the cell with the average height of the 4
-corner heights.
          
-
          const cellsAcross = width - 1;
-const cellsDeep = height - 1;
-for (let z = 0; z < cellsDeep; ++z) {
-  for (let x = 0; x < cellsAcross; ++x) {
-    // compute row offsets into the height data
-    // we multiply by 4 because the data is R,G,B,A but we
-    // only care about R
-    const base0 = (z * width + x) * 4;
-    const base1 = base0 + (width * 4);
-
-    // look up the height for the for points
-    // around this cell
-    const h00 = data[base0] / 32;
-    const h01 = data[base0 + 4] / 32;
-    const h10 = data[base1] / 32;
-    const h11 = data[base1 + 4] / 32;
-    // compute the average height
-    const hm = (h00 + h01 + h10 + h11) / 4;
-
-    // the corner positions
-    const x0 = x;
-    const x1 = x + 1;
-    const z0 = z;
-    const z1 = z + 1;
-
-    // remember the first index of these 5 vertices
-    const ndx = geometry.vertices.length;
-
-    // add the 4 corners for this cell and the midpoint
-    geometry.vertices.push(
-      new THREE.Vector3(x0, h00, z0),
-      new THREE.Vector3(x1, h01, z0),
-      new THREE.Vector3(x0, h10, z1),
-      new THREE.Vector3(x1, h11, z1),
-      new THREE.Vector3((x0 + x1) / 2, hm, (z0 + z1) / 2),
-    );
-
          
-
          We'll then make 4 triangles from those 5 vertices
          
-
          
-
-
              // create 4 triangles
-    geometry.faces.push(
-      new THREE.Face3(ndx + 0, ndx + 4, ndx + 1),
-      new THREE.Face3(ndx + 1, ndx + 4, ndx + 3),
-      new THREE.Face3(ndx + 3, ndx + 4, ndx + 2),
-      new THREE.Face3(ndx + 2, ndx + 4, ndx + 0),
-    );
-
-    // add the texture coordinates for each vertex of each face
-    const u0 = x / cellsAcross;
-    const v0 = z / cellsDeep;
-    const u1 = (x + 1) / cellsAcross;
-    const v1 = (z + 1) / cellsDeep;
-    const um = (u0 + u1) / 2;
-    const vm = (v0 + v1) / 2;
-    geometry.faceVertexUvs[0].push(
-      [ new THREE.Vector2(u0, v0), new THREE.Vector2(um, vm), new THREE.Vector2(u1, v0) ],
-      [ new THREE.Vector2(u1, v0), new THREE.Vector2(um, vm), new THREE.Vector2(u1, v1) ],

            That seems to work but unfortunately we lost the colors.
            
-
            Three.js does not support morphtarget colors and in fact this is an issue
-with the original webgl globe.
-Basically it just makes colors for the first data set. Any other datasets
-use the same colors even if they are vastly different.
            
-
            Let's see if we can add support for morphing the colors. This might
-be brittle. The least brittle way would probably be to 100% write our own
-shaders but I think it would be useful to see how to modify the built
-in shaders.
            
-
            The first thing we need to do is make the code extract color a BufferAttribute from

            We then need to modify the three.js shader. Three.js materials have an
-Material.onBeforeCompile property we can assign a function. It gives us a
-chance to modify the material's shader before it is passed to WebGL. In fact the
-shader that is provided is actually a special three.js only syntax of shader
-that lists a bunch of shader chunks that three.js will substitute with the
-actual GLSL code for each chunk. Here is what the unmodified vertex shader code

            Three.js also sorts morphtargets and applies only the highest influences. This

            VR
            
+

+        
            
+          
            Making a VR app in three.js is pretty simple. You basically just have to tell
+three.js you want to use WebXR. If you think about it a few things about WebXR
+should be clear. Which way the camera is pointing is supplied by the VR system
+itself since the user turns their head to choose a direction to look. Similarly
+the field of view and aspect will be supplied by the VR system since each system
+has a different field of view and display aspect.
            
+
            Let's take an example from the article on making a responsive webpage
+and make it support VR.
            
+
            Before we get started you're going to need a VR capable device like an Android
+smartphone, Google Daydream, Oculus Go, Oculus Rift, Vive, Samsung Gear VR., an
+iPhone with a WebXR browser.
            
+
            Next, if you are running locally you need to run a simple web server like is
+covered in the article on setting up. 
            
+
            If the device you are using to view VR is not the same computer you're running
+on you need to serve your webpage via https or else the browser will not allow using
+the WebXR API. The server mentioned in the article on setting up
+called Servez has an option to use https. 
+Check it and start the server. 
            
+
            
+
+
            The note the URLs. You need the one that is your computer's local ipaddress.
+It will usually start with 192, 172 or 10. Type that full address, including the https:// part
+into your VR device's browser. Note: Your computer and your VR device need to be on the same local network
+or WiFi and you probably need to be on a home network. note: Many cafes are setup to disallow this kind of
+machine to machine connection.
            
+
            You'll be greeted with an error something like the one below. Click "advanced" and then click
+proceed.
            
+
            
+
+
            Now you can run your examples.
            
+
            If you're really going to do WebXR development another thing you should learn about is
+remote debugging
+so that you can see console warnings, errors, and of course actually 
+debug your code.
            
+
            If you just want to see the code work below you can just run the code from
+this site.
            
+
            The first thing we need to do is include the VR support after
+including three.js
            
+
            import * as THREE from 'three';
++import {VRButton} from 'three/addons/webxr/VRButton.js';
+
            
+
            Then we need to enable three.js's WebXR support and add its
+VR button to our page
            
+
            function main() {
+  const canvas = document.querySelector('#c');
+  const renderer = new THREE.WebGLRenderer({canvas});
++  renderer.xr.enabled = true;
++  document.body.appendChild(VRButton.createButton(renderer));
+
            
+
            We need to let three.js run our render loop. Until now we have used a
+requestAnimationFrame loop but to support VR we need to let three.js handle
+our render loop for us. We can do that by calling
+WebGLRenderer.setAnimationLoop and passing a function to call for the loop.
            
+
            function render(time) {
+  time *= 0.001;
+
+  if (resizeRendererToDisplaySize(renderer)) {
+    const canvas = renderer.domElement;
+    camera.aspect = canvas.clientWidth / canvas.clientHeight;
+    camera.updateProjectionMatrix();
+  }
+
+  cubes.forEach((cube, ndx) => {
+    const speed = 1 + ndx * .1;
+    const rot = time * speed;
+    cube.rotation.x = rot;
+    cube.rotation.y = rot;
+  });
+
+  renderer.render(scene, camera);
+
+-  requestAnimationFrame(render);
+}
+
+-requestAnimationFrame(render);
++renderer.setAnimationLoop(render);
+
            
+
            There is one more detail. We should probably set a camera height
+that's kind of average for a standing user.
            
+
            const camera = new THREE.PerspectiveCamera(fov, aspect, near, far);
++camera.position.set(0, 1.6, 0);
+
            
+
            and move the cubes up to be in front of the camera
            
+
            const cube = new THREE.Mesh(geometry, material);
+scene.add(cube);
+
+cube.position.x = x;
++cube.position.y = 1.6;
++cube.position.z = -2;
+
            
+
            We set them to z = -2 since the camera will now be at z = 0 and
+camera defaults to looking down the -z axis.
            
+
            This brings up an extremely important point. Units in VR are in meters.
+In other words One Unit = One Meter. This means the camera is 1.6 meters above 0.
+The cube's centers are 2 meters in front of the camera. Each cube
+is 1x1x1 meter large. This is important because VR needs to adjust things to the
+user in the real world. That means we need the units used in three.js to match
+the user's own movements.
            
+
            And with that we should get 3 spinning cubes in front
+of the camera with a button to enter VR.
            
+
            
+  
            
+  click here to open in a separate window
+
            
+
+
            
+
            I find that VR works better if we have something surrounding the camera like
+room for reference so let's add a simple grid cubemap like we covered in
+the article on backgrounds. We'll just use the same grid
+texture for each side of the cube which will give as a grid room.
            
+
            const scene = new THREE.Scene();
++{
++  const loader = new THREE.CubeTextureLoader();
++  const texture = loader.load([
++    'resources/images/grid-1024.png',
++    'resources/images/grid-1024.png',
++    'resources/images/grid-1024.png',
++    'resources/images/grid-1024.png',
++    'resources/images/grid-1024.png',
++    'resources/images/grid-1024.png',
++  ]);
++  scene.background = texture;
++}
+
            
+
            That's better.
            
+
            
+  
            
+  click here to open in a separate window
+
            
+
+
            
+
            Note: To actually see VR you will need a WebXR compatible device.
+I believe most Android Phones can support WebXR using Chrome or Firefox.
+For iOS you might be able to use this WebXR App
+though in general WebXR support on iOS is unsupported as of May 2019.
            
+
            To use WebXR on Android or iPhone you'll need a VR Headset
+for phones. You can get them for anywhere from $5 for one made of cardboard
+to $100. Unfortunately I don't know which ones to recommend. I've purchased
+6 of them over the years and they are all of varying quality. I've
+never paid more than about $25.
            
+
            Just to mention some of the issues
            
+
              
+
            1. Do they fit your phone
              
+
              Phones come in a variety of sizes and so the VR headsets need to match.
+Many headsets claim to match a large variety of sizes. My experience
+is the more sizes they match the worse they actually are since instead
+of being designed for a specific size they have to make compromises
+to match more sizes. Unfortunately multi-size headsets are the most common type.
              
+
              2. 
+
            2. Can they focus for your face
              
+
              Some devices have more adjustments than others. Generally there
+are at most 2 adjustments. How far the lenses are from your eyes
+and how far apart the lenses are.
              
+
              3. 
+
            3. Are they too reflective
              
+
              Many headsets of a cone of plastic from your eye to the phone.
+If that plastic is shinny or reflective then it will act like
+a mirror reflecting the screen and be very distracting.
              
+
              Few if any of the reviews seem to cover this issue.
              
+
              4. 
+
            4. Are the comfortable on your face.
              
+
              Most of the devices rest on your nose like a pair of glasses.
+That can hurt after a few minutes. Some have straps that go around
+your head. Others have a 3rd strap that goes over your head. These
+may or may not help keep the device at the right place.
              
+
              It turns out for most (all?) devices, you eyes need to be centered
+with the lenses. If the lenses are slightly above or below your
+eyes the image gets out of focus. This can be very frustrating
+as things might start in focus but 45-60 seconds later the device
+has shifted up or down 1 millimeter and you suddenly realize you've
+been struggling to focus on a blurry image.
              
+
              5. 
+
            5. Can they support your glasses.
              
+
              If you wear eye glasses then you'll need to read the reviews to see
+if a particular headset works well with eye glasses.
              
+
              6. 
+
            
+
            I really can't make any recommendations unfortunately. Google has some
+cheap recommendations made from cardboard
+some of them as low as $5 so maybe start there and if you enjoy it
+then consider upgrading. $5 is like the price of 1 coffee so seriously, give it try!
            
+
            There are also 3 basic types of devices.
            
+
              
+
            1. 3 degrees of freedom (3dof), no input device
              
+
              This is generally the phone style although sometimes you can
+buy a 3rd party input device. The 3 degrees of freedom
+mean you can look up/down (1), left/right(2) and you can tilt
+your head left and right (3).
              
+
              2. 
+
            2. 3 degrees of freedom (3dof) with 1 input device (3dof)
              
+
              This is basically Google Daydream and Oculus GO
              
+
              These also allow 3 degrees of freedom and include a small
+controller that acts like a laser pointer inside VR.
+The laser pointer also only has 3 degrees of freedom. The
+system can tell which way the input device is pointing but
+it can not tell where the device is.
              
+
              3. 
+
            3. 6 degrees of freedom (6dof) with input devices (6dof)
              
+
              These are the real deal haha. 6 degrees of freedom
+means not only do these device know which way you are looking
+but they also know where your head actually is. That means
+if you move from left to right or forward and back or stand up / sit down
+the devices can register this and everything in VR moves accordingly.
+It's spookily and amazingly real feeling. With a good demo
+you'll be blown away or at least I was and still am.
              
+
              Further these devices usually include 2 controllers, one
+for each hand and the system can tell exactly where your
+hands are and which way they are oriented and so you can
+manipulate things in VR by just reaching out, touching,
+pushing, twisting, etc...
              
+
              6 degree of freedom devices include the Vive and Vive Pro,
+the Oculus Rift and Quest, and I believe all of the Windows MR devices.
              
+
              4. 
+
            
+
            With all that covered I don't for sure know which devices will work with WebXR.
+I'm 99% sure that most Android phones will work when running Chrome. You may
+need to turn on WebXR support in about:flags. I also know Google
+Daydream will also work and similarly you need to enable WebXR support in
+about:flags. Oculus Rift, Vive, and Vive Pro will work via
+Chrome or Firefox. I'm less sure about Oculus Go and Oculus Quest as both of
+them use custom OSes but according to the internet they both appear to work.
            
+
            Okay, after that long detour about VR Devices and WebXR
+there's some things to cover
            
+
              
+
            • Supporting both VR and Non-VR
              
+
              AFAICT, at least as of r112, there is no easy way to support
+both VR and non-VR modes with three.js. Ideally
+if not in VR mode you'd be able to control the camera using
+whatever means you want, for example the OrbitControls,
+and you'd get some kind of event when switching into and
+out of VR mode so that you could turn the controls on/off.
              
+
              • 
+
            
+
            If three.js adds some support to do both I'll try to update
+this article. Until then you might need 2 versions of your 
+site OR pass in a flag in the URL, something like
            
+
            https://mysite.com/mycooldemo?allowvr=true
+
            Then we could add some links in to switch modes
            
+
            <body>
+  <canvas id="c"></canvas>
++  <div class="mode">
++    <a href="?allowvr=true" id="vr">Allow VR</a>
++    <a href="?" id="nonvr">Use Non-VR Mode</a>
++  </div>
+</body>
+
            
+
            and some CSS to position them
            
+
            body {
+    margin: 0;
+}
+#c {
+    width: 100%;
+    height: 100%;
+    display: block;
+}
++.mode {
++  position: absolute;
++  right: 1em;
++  top: 1em;
++}
+
            
+
            in your code you could use that parameter like this
            
+
            function main() {
+  const canvas = document.querySelector('#c');
+  const renderer = new THREE.WebGLRenderer({canvas});
+-  renderer.xr.enabled = true;
+-  document.body.appendChild(VRButton.createButton(renderer));
+
+  const fov = 75;
+  const aspect = 2;  // the canvas default
+  const near = 0.1;
+  const far = 5;
+  const camera = new THREE.PerspectiveCamera(fov, aspect, near, far);
+  camera.position.set(0, 1.6, 0);
+
++  const params = (new URL(document.location)).searchParams;
++  const allowvr = params.get('allowvr') === 'true';
++  if (allowvr) {
++    renderer.xr.enabled = true;
++    document.body.appendChild(VRButton.createButton(renderer));
++    document.querySelector('#vr').style.display = 'none';
++  } else {
++    // no VR, add some controls
++    const controls = new OrbitControls(camera, canvas);
++    controls.target.set(0, 1.6, -2);
++    controls.update();
++    document.querySelector('#nonvr').style.display = 'none';
++  }
+
            
+
            Whether that's good or bad I don't know. I have a feeling the differences
+between what's needed for VR and what's needed for non-VR are often
+very different so for all but the most simple things maybe 2 separate pages
+are better? You'll have to decide.
            
+
            Note for various reasons this will not work in the live editor
+on this site so if you want to check it out 
+click here.
+It should start in non-VR mode and you can use the mouse or fingers to move
+the camera. Clicking "Allow VR" should switch to allow VR mode and you should
+be able to click "Enter VR" if you're on a VR device.

            • Deciding on the level of VR support
              
+
              Above we covered 3 types of VR devices. 
              
+
                
+
              • 3DOF no input
                • 
+
              • 3DOF + 3DOF input
                • 
+
              • 6DOF + 6DOF input
                • 
+
              
+
              You need to decide how much effort you're willing to put in
+to support each type of device.
              
+
              For example the simplest device has no input. The best you can
+generally do is make it so there are some buttons or objects in the user's view
+and if the user aligns some marker in the center of the display
+on those objects for 1/2 a second or so then that button is clicked.
+A common UX is to display a small timer that will appear over the object indicating
+if you keep the marker there for a moment the object/button will be selected.
              
+
              Since there is no other input that's about the best you can do
              
+
              The next level up you have one 3DOF input device. Generally it
+can point at things and the user has at least 2 buttons. The Daydream
+also has a touchpad which provides normal touch inputs.
              
+
              In any case if a user has this type of device it's far more
+comfortable for the user to by able to point at things with
+their controller than it is to make them do it with their
+head by looking at things.
              
+
              A similar level to that might be 3DOF or 6DOF device with a
+game console controller. You'll have to decide what to do here.
+I suspect the most common thing is the user still has to look
+to point and the controller is just used for buttons.
              
+
              The last level is a user with a 6DOF headset and 2 6DOF controllers.
+Those users will find an experience that is only 3DOF to often
+be frustrating. Similarly they usually expect to be able to 
+virtually manipulate things with their hands in VR so you'll
+have to decide if you want to support that or not.
              
+
              • 
+
            
+
            As you can see getting started in VR is pretty easy but
+actually making something shippable in VR will require
+lots of decision making and design.
            
+
            This was a pretty brief intro into VR with three.js. We'll
+cover some of the input methods in future articles.

-        
            
-          
            Making a VR app in three.js is pretty simple. You basically just have to tell
-three.js you want to use WebXR. If you think about it a few things about WebXR
-should be clear. Which way the camera is pointing is supplied by the VR system
-itself since the user turns their head to choose a direction to look. Similarly
-the field of view and aspect will be supplied by the VR system since each system
-has a different field of view and display aspect.
            
-
            Let's take an example from the article on making a responsive webpage
-and make it support VR.
            
-
            Before we get started you're going to need a VR capable device like an Android
-smartphone, Google Daydream, Oculus Go, Oculus Rift, Vive, Samsung Gear VR., an
-iPhone with a WebXR browser.
            
-
            Next, if you are running locally you need to run a simple web server like is
-covered in the article on setting up. 
            
-
            If the device you are using to view VR is not the same computer you're running
-on you need to serve your webpage via https or else the browser will not allow using
-the WebXR API. The server mentioned in the article on setting up
-called Servez has an option to use https. 
-Check it and start the server. 
            
-
            
-
-
            The note the URLs. You need the one that is your computer's local ipaddress.
-It will usually start with 192, 172 or 10. Type that full address, including the https:// part
-into your VR device's browser. Note: Your computer and your VR device need to be on the same local network
-or WiFi and you probably need to be on a home network. note: Many cafes are setup to disallow this kind of
-machine to machine connection.
            
-
            You'll be greeted with an error something like the one below. Click "advanced" and then click
-proceed.
            
-
            
-
-
            Now you can run your examples.
            
-
            If you're really going to do WebXR development another thing you should learn about is
-remote debugging
-so that you can see console warnings, errors, and of course actually 
-debug your code.
            
-
            If you just want to see the code work below you can just run the code from
-this site.
            
-
            The first thing we need to do is include the VR support after
-including three.js
            
-
            import * as THREE from '/build/three.module.js';
-+import {VRButton} from '/examples/jsm/webxr/VRButton.js';
-
            
-
            Then we need to enable three.js's WebXR support and add its
-VR button to our page
            
-
            function main() {
-  const canvas = document.querySelector('#c');
-  const renderer = new THREE.WebGLRenderer({canvas});
-+  renderer.xr.enabled = true;
-+  document.body.appendChild(VRButton.createButton(renderer));
-
            
-
            We need to let three.js run our render loop. Until now we have used a
-requestAnimationFrame loop but to support VR we need to let three.js handle
-our render loop for us. We can do that by calling
-WebGLRenderer.setAnimationLoop and passing a function to call for the loop.
            
-
            function render(time) {
-  time *= 0.001;
-
-  if (resizeRendererToDisplaySize(renderer)) {
-    const canvas = renderer.domElement;
-    camera.aspect = canvas.clientWidth / canvas.clientHeight;
-    camera.updateProjectionMatrix();
-  }
-
-  cubes.forEach((cube, ndx) => {
-    const speed = 1 + ndx * .1;
-    const rot = time * speed;
-    cube.rotation.x = rot;
-    cube.rotation.y = rot;
-  });
-
-  renderer.render(scene, camera);
-
--  requestAnimationFrame(render);
-}
-
--requestAnimationFrame(render);
-+renderer.setAnimationLoop(render);
-
            
-
            There is one more detail. We should probably set a camera height
-that's kind of average for a standing user.
            
-
            const camera = new THREE.PerspectiveCamera(fov, aspect, near, far);
-+camera.position.set(0, 1.6, 0);
-
            
-
            and move the cubes up to be in front of the camera
            
-
            const cube = new THREE.Mesh(geometry, material);
-scene.add(cube);
-
-cube.position.x = x;
-+cube.position.y = 1.6;
-+cube.position.z = -2;
-
            
-
            We set them to z = -2 since the camera will now be at z = 0 and
-camera defaults to looking down the -z axis.
            
-
            This brings up an extremely important point. Units in VR are in meters.
-In other words One Unit = One Meter. This means the camera is 1.6 meters above 0.
-The cube's centers are 2 meters in front of the camera. Each cube
-is 1x1x1 meter large. This is important because VR needs to adjust things to the
-user in the real world. That means we need the units used in three.js to match
-the user's own movements.
            
-
            And with that we should get 3 spinning cubes in front
-of the camera with a button to enter VR.

-
            
-
-
            
-
            I find that VR works better if we have something surrounding the camera like
-room for reference so let's add a simple grid cubemap like we covered in
-the article on backgrounds. We'll just use the same grid
-texture for each side of the cube which will give as a grid room.
            
-
            const scene = new THREE.Scene();
-+{
-+  const loader = new THREE.CubeTextureLoader();
-+  const texture = loader.load([
-+    'resources/images/grid-1024.png',
-+    'resources/images/grid-1024.png',
-+    'resources/images/grid-1024.png',
-+    'resources/images/grid-1024.png',
-+    'resources/images/grid-1024.png',
-+    'resources/images/grid-1024.png',
-+  ]);
-+  scene.background = texture;
-+}
-
            
-
            That's better.
            
-
            
-  
            
-  click here to open in a separate window
-
            
-
-
            
-
            Note: To actually see VR you will need a WebXR compatible device.
-I believe most Android Phones can support WebXR using Chrome or Firefox.
-For iOS you might be able to use this WebXR App
-though in general WebXR support on iOS is unsupported as of May 2019.
            
-
            To use WebXR on Android or iPhone you'll need a VR Headset
-for phones. You can get them for anywhere from $5 for one made of cardboard
-to $100. Unfortunately I don't know which ones to recommend. I've purchased
-6 of them over the years and they are all of varying quality. I've
-never paid more than about $25.
            
-
            Just to mention some of the issues
            
-
              
-
            1. Do they fit your phone
              
-
              Phones come in a variety of sizes and so the VR headsets need to match.
-Many headsets claim to match a large variety of sizes. My experience
-is the more sizes they match the worse they actually are since instead
-of being designed for a specific size they have to make compromises
-to match more sizes. Unfortunately multi-size headsets are the most common type.
              
-
              2. 
-
            2. Can they focus for your face
              
-
              Some devices have more adjustments than others. Generally there
-are at most 2 adjustments. How far the lenses are from your eyes
-and how far apart the lenses are.
              
-
              3. 
-
            3. Are they too reflective
              
-
              Many headsets of a cone of plastic from your eye to the phone.
-If that plastic is shinny or reflective then it will act like
-a mirror reflecting the screen and be very distracting.
              
-
              Few if any of the reviews seem to cover this issue.
              
-
              4. 
-
            4. Are the comfortable on your face.
              
-
              Most of the devices rest on your nose like a pair of glasses.
-That can hurt after a few minutes. Some have straps that go around
-your head. Others have a 3rd strap that goes over your head. These
-may or may not help keep the device at the right place.
              
-
              It turns out for most (all?) devices, you eyes need to be centered
-with the lenses. If the lenses are slightly above or below your
-eyes the image gets out of focus. This can be very frustrating
-as things might start in focus but 45-60 seconds later the device
-has shifted up or down 1 millimeter and you suddenly realize you've
-been struggling to focus on a blurry image.
              
-
              5. 
-
            5. Can they support your glasses.
              
-
              If you wear eye glasses then you'll need to read the reviews to see
-if a particular headset works well with eye glasses.
              
-
              6. 
-
            
-
            I really can't make any recommendations unfortunately. Google has some
-cheap recommendations made from cardboard
-some of them as low as $5 so maybe start there and if you enjoy it
-then consider upgrading. $5 is like the price of 1 coffee so seriously, give it try!
            
-
            There are also 3 basic types of devices.
            
-
              
-
            1. 3 degrees of freedom (3dof), no input device
              
-
              This is generally the phone style although sometimes you can
-buy a 3rd party input device. The 3 degrees of freedom
-mean you can look up/down (1), left/right(2) and you can tilt
-your head left and right (3).
              
-
              2. 
-
            2. 3 degrees of freedom (3dof) with 1 input device (3dof)
              
-
              This is basically Google Daydream and Oculus GO
              
-
              These also allow 3 degrees of freedom and include a small
-controller that acts like a laser pointer inside VR.
-The laser pointer also only has 3 degrees of freedom. The
-system can tell which way the input device is pointing but
-it can not tell where the device is.
              
-
              3. 
-
            3. 6 degrees of freedom (6dof) with input devices (6dof)
              
-
              These are the real deal haha. 6 degrees of freedom
-means not only do these device know which way you are looking
-but they also know where your head actually is. That means
-if you move from left to right or forward and back or stand up / sit down
-the devices can register this and everything in VR moves accordingly.
-It's spookily and amazingly real feeling. With a good demo
-you'll be blown away or at least I was and still am.
              
-
              Further these devices usually include 2 controllers, one
-for each hand and the system can tell exactly where your
-hands are and which way they are oriented and so you can
-manipulate things in VR by just reaching out, touching,
-pushing, twisting, etc...
              
-
              6 degree of freedom devices include the Vive and Vive Pro,
-the Oculus Rift and Quest, and I believe all of the Windows MR devices.
              
-
              4. 
-
            
-
            With all that covered I don't for sure know which devices will work with WebXR.
-I'm 99% sure that most Android phones will work when running Chrome. You may
-need to turn on WebXR support in about:flags. I also know Google
-Daydream will also work and similarly you need to enable WebXR support in
-about:flags. Oculus Rift, Vive, and Vive Pro will work via
-Chrome or Firefox. I'm less sure about Oculus Go and Oculus Quest as both of
-them use custom OSes but according to the internet they both appear to work.
            
-
            Okay, after that long detour about VR Devices and WebXR
-there's some things to cover
            
-
              
-
            • Supporting both VR and Non-VR
              
-
              AFAICT, at least as of r112, there is no easy way to support
-both VR and non-VR modes with three.js. Ideally
-if not in VR mode you'd be able to control the camera using
-whatever means you want, for example the OrbitControls,
-and you'd get some kind of event when switching into and
-out of VR mode so that you could turn the controls on/off.
              
-
              • 
-
            
-
            If three.js adds some support to do both I'll try to update
-this article. Until then you might need 2 versions of your 
-site OR pass in a flag in the URL, something like
            
-
            https://mysite.com/mycooldemo?allowvr=true
-
            Then we could add some links in to switch modes
            
-
            <body>
-  <canvas id="c"></canvas>
-+  <div class="mode">
-+    <a href="?allowvr=true" id="vr">Allow VR</a>
-+    <a href="?" id="nonvr">Use Non-VR Mode</a>
-+  </div>
-</body>
-
            
-
            and some CSS to position them
            
-
            body {
-    margin: 0;
-}
-#c {
-    width: 100%;
-    height: 100%;
-    display: block;
-}
-+.mode {
-+  position: absolute;
-+  right: 1em;
-+  top: 1em;
-+}
-
            
-
            in your code you could use that parameter like this
            
-
            function main() {
-  const canvas = document.querySelector('#c');
-  const renderer = new THREE.WebGLRenderer({canvas});
--  renderer.xr.enabled = true;
--  document.body.appendChild(VRButton.createButton(renderer));
-
-  const fov = 75;
-  const aspect = 2;  // the canvas default
-  const near = 0.1;
-  const far = 5;
-  const camera = new THREE.PerspectiveCamera(fov, aspect, near, far);
-  camera.position.set(0, 1.6, 0);
-
-+  const params = (new URL(document.location)).searchParams;
-+  const allowvr = params.get('allowvr') === 'true';
-+  if (allowvr) {
-+    renderer.xr.enabled = true;
-+    document.body.appendChild(VRButton.createButton(renderer));
-+    document.querySelector('#vr').style.display = 'none';
-+  } else {
-+    // no VR, add some controls
-+    const controls = new OrbitControls(camera, canvas);
-+    controls.target.set(0, 1.6, -2);
-+    controls.update();
-+    document.querySelector('#nonvr').style.display = 'none';
-+  }
-
            
-
            Whether that's good or bad I don't know. I have a feeling the differences
-between what's needed for VR and what's needed for non-VR are often
-very different so for all but the most simple things maybe 2 separate pages

            • Deciding on the level of VR support
              
-
              Above we covered 3 types of VR devices. 
              
-
                
-
              • 3DOF no input
                • 
-
              • 3DOF + 3DOF input
                • 
-
              • 6DOF + 6DOF input
                • 
-
              
-
              You need to decide how much effort you're willing to put in
-to support each type of device.
              
-
              For example the simplest device has no input. The best you can
-generally do is make it so there are some buttons or objects in the user's view
-and if the user aligns some marker in the center of the display
-on those objects for 1/2 a second or so then that button is clicked.
-A common UX is to display a small timer that will appear over the object indicating
-if you keep the marker there for a moment the object/button will be selected.
              
-
              Since there is no other input that's about the best you can do
              
-
              The next level up you have one 3DOF input device. Generally it
-can point at things and the user has at least 2 buttons. The Daydream
-also has a touchpad which provides normal touch inputs.
              
-
              In any case if a user has this type of device it's far more
-comfortable for the user to by able to point at things with
-their controller than it is to make them do it with their
-head by looking at things.
              
-
              A similar level to that might be 3DOF or 6DOF device with a
-game console controller. You'll have to decide what to do here.
-I suspect the most common thing is the user still has to look
-to point and the controller is just used for buttons.
              
-
              The last level is a user with a 6DOF headset and 2 6DOF controllers.
-Those users will find an experience that is only 3DOF to often
-be frustrating. Similarly they usually expect to be able to 
-virtually manipulate things with their hands in VR so you'll
-have to decide if you want to support that or not.
              
-
              • 
-
            
-
            As you can see getting started in VR is pretty easy but
-actually making something shippable in VR will require
-lots of decision making and design.
            
-
            This was a pretty brief intro into VR with three.js. We'll
-cover some of the input methods in future articles.

            Le brouillard dans un moteur 3D est généralement un moyen d'atténuer les couleurs de la scène vers une couleur désirée en fonction de la distance par rapport à la caméra. Dans Three.js, vous pouvez ajouter du brouillard en crééant dans la propriété fog de votre scène, soit un objet Fog soit un objet FogExp2.
            
 
            Fog permet de définir les paramètres near et far en tant que distance par rapport à la caméra. Ce qui se trouve entre la caméra et near n'est pas affecté par le brouillard.
 Ce qui est au-delà de far est complètement dans le brouillard. Ce qui se trouve entre les deux, est altéré par le brouillard.

Les pièces et la maison faisant plus de 4 mètres, il vous faudra donc définir les matériaux utilisés à l'intérieur de la maison pour qu'il n'y ait pas de brouillard, sinon, cela donnerait l'aspect non désiré suivant :

            fog: true, all
            
+    
            fog à true sur tous les objets.
            
   
            
 
            
 
-
            Remarquez que les murs et le plafond au fond de la pièce sont dans le brouillard. En désactivant le brouillard sur les matériaux de la maison, on résoud le problème.

            Pourquoi avoir les 3, si MeshPhongMaterial peut faire les mêmes choses que MeshBasicMaterial et MeshLambertMaterial ? La raison est simple. Le materials le plus sophistiqué nécessite aussi plus de puissance de la part du GPU. Sur un GPU plus lent comme par exemple sur un téléphone mobile, vous souhaiterez peut-être réduire la puissance du GPU  en utilisant l'un des materials les moins complexes. Il s'ensuit également que si vous n'avez pas besoin des fonctionnalités supplémentaires, utilisez le materials le plus simple. Si vous n'avez pas besoin de l'éclairage et de la surbrillance spéculaire, utilisez le MeshBasicMaterial.

-avec une grande différence. Plutôt que d'ombrager en douceur, il utilise une carte de dégradé (une texture X par 1) pour décider comment ombrager. La valeur par défaut utilise une carte de dégradé dont la luminosité est de 70 % pour les premiers 70 % et 100 % après, mais vous pouvez fournir votre propre carte de dégradé. Cela finit par donner un look 2 tons qui ressemble à un dessin animé.

            Ensuite, il y a 2 materials de rendu physique. Le rendu physique est souvent abrégé PBR.
            
-
            Les materials ci-dessus utilisent des mathématiques simples pour créer des materials qui semblent 3D, mais ne réagissent pas comme dans le monde réel. Les 2 materials PBR utilisent des mathématiques beaucoup plus complexes pour se rapprocher de ce qui se passe réellement dans le monde réel.

            Le premier est MeshStandardMaterial. La plus grande différence entre MeshPhongMaterial et MeshStandardMaterial est qu'il utilise des paramètres différents.
-MeshPhongMaterial a un paramètre shininess. MeshStandardMaterial a 2 paramètres roughness (rugosité) et metalness (metalique).

            Basiquement, roughness est l'opposé de shininess.

            L'autre paramètre, metalness, indique
 à quel point le matériau est métallique. Les métaux se comportent différemment des non-métaux. 0
 pour le non-métal et 1 pour le métal.

            Mais allons-y une étape à la fois! Imaginez que nous voulions faire un diagramme du Soleil, de la Terre et de la Lune. Nous allons commencer par le Soleil en créant une simpme sphère et en la mettant à l'origine. Remarque : Nous utilisons le Soleil, la Terre et la Lune comme démonstration de l'utilisation d'une scène. Bien sûr, le vrai Soleil, la Terre et la Lune utilisent la physique, mais pour nos besoins, nous allons faire semblant.

Le moyen le plus simple de le faire est d'utiliser la fonction lookAt. Cette fonction oriente la caméra pour "regarder" vers la position que nous passons à lookAt. Avant de faire cela, nous devons cependant indiquer à la caméra dans quelle direction le haut de la caméra est orienté ou plutôt dans quelle direction est "vers le haut" pour la caméra. Pour la plupart des situations, un Y positif est suffisant, mais puisque nous regardons vers le bas, nous devons dire à la caméra que Z positif est levé.
