Re: [pygame] Collision Detection with Pygame/OpenGL Surfaces

I'm not entirely sure, but I think what you actually want is 
http://pyopengl.sourceforge.net/documentation/manual/gluPickMatrix.3G.xml
this lets you render a small portion of the scene (like the portion 
that's under the cursor) and stores the rendered objects into a 
selection buffer.
