It sounds as if you are worried about irrational
numbers and all kinds of monsters creeping in
when you do geometric operations with real numbers,
even if you started out with rational numbers.

So, it would seem that sci.math is the correct
newsgroup to ask this on, but all you will get
is a lot of insult from arrogant people.

Instead, can you answer why you think a voxel
model isn't enough for your discrete needs? What
do you think your discrete and finite model should
provide in addition to a basic cellular model?
