Installing

1. Install Unity3d >=2019.3.0f3
2. Clone project
3. Open project in Unity

Using

1. Build project (File -> Build Settings -> Select your platform)
2. Move config files (Fen.data, Interval.json) and textures to build project.
3. Run executable file.

Configs

The file Fen.data contains the positions of the chess pieces (one per line) in the format FEN.

The file Interval.json contains generation parameters. Values ​​are randomly selected from the interval. Angles in degrees, dimensions in centimeters relative to each other.

Parameters:

• boardPositionX, boardPositionY: chess board position
• cameraRadius, cameraPhi, cameraTheta: camera position in polar coordinates
• spotLightNumber: number of spotlights
• spotLightPositionX, spotLightPositionY, spotLightPositionZ: spotlights position
• spotLightBrightness: spotlights brightness
• ambientLightBrightness: general light brightness
• ambientLightPhi: general light position
• chessBoardWidth: chess board width
• chessmanOffset: displacement of figures relative to the center of the cell
• screenshotPerFen: number of screenshots for one FEN
• screenshotWidth, screenshotHeight: screenshot size in pixels
• pathToTableTexture: path to table texture
• pathToFloorTexture: path to floor texture
