Projective texturing texture coordinates
At its most basic, projective texturing is the use of a 3D texture coordinate to look up into a 2D texture image. The (s, t) coordinates are divided by the (r) coordinate such that a texel is fetched using (s/r, t/r). There is a special built-in function in the OpenGL ES Shading Language to do projective texturing called texture2DProj.
