Collision between triangulated surfaces

Is there am OPENGL library which will allow detection of collision. I have written my own code using vector algebra but as soon as the number of edges on each surface exceeds 100, the speed of execution drops.

Hi !

There are a few, at least there was a few years ago when I looked for one, I don’t have any URL’s here, but google for collision detection and opengl and you should get some hits.
