Source code? I really, really want to try something like this but I've never done GP and I'm not sure where to start.

In lieue of the source code, can anyone point me to a reference on GP and maybe something about image generation in C? In particular, what's an efficient graphics pipeline for converting all of these polygons to pixels? Something like bresenham for the edges and then additive coloring in the middle? And then how do I convert an RGB pixel array into some reasonable image format? I apologize for my ignorance, I don't even know what to start googling.

I think it would be a good exercise for me to write something like this from scratch on my own, just want some pointers to start.
