I''m about 3300 lines into my first 3D graphics engine, and already I''m noticing the biggest slow down comes when the camera gets rotated. I''m basically just using the opengl rotation functions right now. Are there any cool optimizations for rotations?

Do you use glPush/PopMatrix()?

Heh never mind. I was doing it wrong. It runs perfectly normally.
