Like Dirac/Schroedinger?

The trick would be to construct it in a way that uses mainly integer arithmetic...
I'm not sure if n-gons have any tangible benefit over squares, other than avoiding square macroblocks. Octrees might be useful for some scenes (time being the third dimension), but not in the general case.
