BSP trees

Hi, I would like to know what are BSP trees and how to use them. Does anyone have a link to a good BSP tutorial, note that I don’t even know what they are, so the tut has to be for beginners!

Check out Mr. GameMaker’s tutorials . He has 2 very well written tutorials which describe BSPs at a beginner level. He uses D3D for rendering, but you’ll learn everything you need to know about BSPs.

You should check out the BSP tree FAQ link. Most of your questions should be answered there.
