Well, here is my problem. I can detect collision between two uncomplicated objects(plane, spheres, and such), but now I want to move to a higher level. I am using Nehe''s code for loading Milkshape 3D objects into a scene, and was wondering how I would go about checking for collision with that. How would I check collision between a large model, and a smaller model ? What I plan to do with the smaller one, is make a sphere around the center of the smaller model, and use that to check collision against the larger one. But how would I go about finding the edges of the large model ? Suggesting are needed, validity isn''t necisarry. Just something to get me thinking. Muchos gracias.

I don''''t know what the future holds, but I know who holds the future.
Hmmmm. I''m *trying* to make a raceing type game, and the collision I''m looking for is between track parts, and car\ship\whatever model(not quite sure wich, yet) From the replies I got, I''m not sure my intent was understood, and I apologize for not making my first message acurate enough. Won''t get good answers, unless you ask the right question. 
Not that I''m saying the answers I got were bad, all input is taken gratefully. Thanks again.
