Anyone got any good 3D tutorials? I have studied the basics from the Kiwidog tutorials, so I know how to project a 3D point to a 2D plane(screen) as well as 3D rotation. I have already downloaded some tutorials for rendering basic polygons. That is all, small but good grounds.

Where should I go from there?

PS. I am not using OpenGL or other 3D library because I want a deeper understanding of what I am starting from scratch (with z-buffers! ah!).
