What is the best way to perform collision detection with openGL? Is there a way for retrieving the coordinates of the vertices of an object or what? I’m a beginner and I haven’t thought much about this yet, it’s a question that just occurred to me.
Another of our beloved questions… You could do a little search on the forum about collision detection… There’ll be more discussion than you can count… 
Anyway… No, OpenGL doesn’t help you with collision detection.
