Voxel-based representations should be easily implemented
and converted to control hardware; however, they may not
offer acceptable manipulation flexibility or sufficient
precision at tolerable storage sizes.

A 12 inch cube with 0.005" precision and 24-bit color
(or property) resolution would require >41Gb to store
if every voxel were represented explicitly. While
this can be greatly reduced with coding techniques
such as Octree encoding, it seems that there must
be a more efficient way.
