I was always curious why they were called voxels.  Height mapping makes
a lot of sense to me, but voxels??  A voxel object is something built
out of a bunch of cubes.  During rendering, the cubes are treated like
rectangles according to the perspective postion of them.  This is what
I've learned from some free net sources.  I don't know if it's correct
or not, but it makes sense to me. Pixels form 2d space, voxels
form 3d space.  Pixels are tiny squares, while voxels are tiny cubes.
