Minecraft 4K C++ Port

A while ago I discovered Minecraft4k, a java demo written by Notch fitting into a 4kb object file.  He used software raycasting to rasterize a large 3d array of voxels. The original demo can be played here as an applet:


At the same time I found that Notch had made a Javascript port of the same basic engine, minus user input.


One awesome thing about these two demos is that all of the textures are synthesized proceduraly for space saving reasons.

Seeing his work, I got a strong urge to port the code to C++ and SDL.
