The Graphics Pipeline

More fun than it sounds...

I wanted to do something constructive with my PEY term, so I decided to learn what I could about 3D graphics. When I say "learn" I don't mean any particular library or product like OpenGL or DirectX or POV-Ray (although I did have some fun with POV-Ray). I decided to learn about the math involved so I could write my own 3D library. I was taking home a paycheck and I was feeling brave.

So here we are. The library's name is GP, for Graphics Pipeline (I never said I was creative). It is low level polygon renderer with a design similar to OpenGL, although not identical (OpenGL, for instance does not allow oblique projections, while this API does). I think the shading might be a bit off but...whatever. It was all in good fun and maybe I'll fix it someday.
