Is there a built in function to OpenGl that can determine if 2 polygons are intersecting? If not, how can I find out if they are? This is for collision detection purposes btw.

OpenGL is just a graphics library and as such I don't think it has any collision routines.

No there's not, OpenGL is only a graphics api. You need to do the calculations yourself. I would suggest using bounding volumes before moving down to the individual polygons.

I suggest looking at the Open Dynamics Engine which has both collision and simulation of what happens when you collide.

enum Bool { True, False, FileNotFound };
