OK, i went through my header files (the OpenGL ones) while I was bored and frustrated with the lack of design by 3dfx on my drivers, and found six clipping planes defined, such as CLIP_PLANE0-CLIP_PLANE5. How do I use these? If I could setup plane 0 as the viewport (the window's client area) I could then let OpenGL do all the clipping automatically, but would that cause a super slow-down? I found a TON of tutorials on OpenGL, but none have what I need, so does anybody know where i can find some REAL help files for OpenGL? I *REALLY* need them, since I have found a ton of things that look useful but have no clue what they do. Thanks!
