I'm currently working on a 3D car racing game in C adn DirectX but having trouble with the collision detection. I am using OOBs to detect collisions between the cars but cannot determine the intersection point. I am currently working on a 2D level and ignoring the y component. Admittedly I am not a very strong C programmer! I would appreciate any advice on this subject, any alternative methods of implementing collision detection or any good sites. Thank you very much!
