So Ingo's link to that historical Voro++ image has piqued my interest in an SDL
version.

Here's my first iteration of a basic Voronoi cell generator in 3D, completely in
SDL. This is 100 seed points in a cubic volume, and was pretty slow to parse (19
minutes total render time, almost 18 of which was parsing). The output from the
algorithm is an array of cells, each cell an array of faces, each face an array
of lines, and each line an array of 2 points. The cells were then rendered as
simple meshes, each shrunk slightly towards its seed point.

The method is probably painfully naive and could benefit from all sorts of
optimization, which will probably be my next focus. However, this image is a
good proof of concept!
