3D without a depth buffer

[bakpakin]

Just a little something I made while exploring 3D. It generates a BSP tree to draw polygons without using a depth buffer. Because each polygon has to be drawn separately, this is horribly slow and not practical like LOVE3D, but it was a fun little exercise. You add floors and walls and it generates the bsp tree for you, so you could potentially make this render a complex scene.

The most useful code in here is probably the skybox code, which could stand alone. It works well and turns a single texture into a skybox.

Use WASD to move around, and Q and E to move up and down.
