NB: Here is a better post about the below algorithm. Includes source code. The idea Did you know you can do pixel accurate collision detection using the OpenGL stencil buffer and occlusion queries? I got this idea while working on a 2D/3D game engine (think of a side-scroller but with 3D objects). A proof that [...]
