I REALLY want to get into 3D. I''ve written a couple of games in 2D, but I want to at least start learning the basics of 3D. So far I''ve started learning Direct3D from the SDK, but everywhere on this board I hear about BSP trees and Quarterions (spelled right?). Where do I learn about that kind of stuff. Thanks in advance - Cloxs "When people tell you they want to hear the truth, you know that their lying."

Try reading some books on Computer Graphics. I found a good one called ''Computer Graphics: Principles and Practice". It was really easy to read, has exercises etc.. and you can learn all about vectors, normals, matrices, perspective, projection and the like.

Some people recommend ''Computer Graphics: Principles and Practice'' by Foley etc..

There is an article about Quaternions at Gamasutra. Just follow the link from the Gamedev main page: Programming->3D and theory.

Feel free to e-mail me any basic 3D questions if you need help. Just don''t ask me anything difficult.
