Projected Shadow Maps with Cg and OpenGL

This video demonstrates projected texture mapping and projected shadow mapping. Initially, we see a sample of projected texture mapping on the scene. This is an interesting method that can be used to place decals over existing textures in the scene. The we switch to projected shadow maps and the depth texture is also visualized in the scene.

This demo was created for the following article that describes this technique:
