##What is this ?
This piece of code generates a mesh representing the line of sight of a player in a real time 3D Unity Engine scene.
A picture is worth a thousand words:
##How does it works ?
Since this raycasting script focusses on outer edges detection, it works best with angular objects.
First, let's say we cast 20 rays. Then we compare each pair of rays: if they hit a different scene object, we cast 20 other rays between these 2 rays and so on in a recursive way. When we are done (or we reached the number of maximum iterations), we generate a mesh with all the rays hitpoints using a triangulation algorithm.
From the first to the last iteration of raycasting algorithm, the mesh is generated from the hitpoints
Note: your scene must be closed or it won't work! (the rays must hit something sometime)
