Your question is quite broad. There are many ways to do collision detection, depending on the type of 3D object that you are considering. For example, with convex polyhedras, you can try to a plane that "separates" the two objects. If there is none, then there is a collision.

If you don't mind buying some books, 3D Game Engine Design by David Eberly and Real-Time Rendering by Möller and Haines each devote an entire chapter to collision detection. Möller and Haines' chapter on collision detection is easier to understand, but Eberly's is more comprehensive.

How about answer the question without him sacrificing dinero for some book. Lets say you were making a program with 2 red cubes. One red cube is controlled by the user. The controled red cube moves into the other red cube. How would you detect that?

"A programmer being told to ''''go to'''' hell sees the ''''go to'''' part of the sentence as the bad part."
