Hi,

Mathematica can't handle 3D voronoi at all, and I think that qhull 
doesn't have an option for periodicy. You might consider doing it 
manually: surround the cube with copies of itself and compute the 
voronoi tesselation. Then delete the objects where none of the vertices 
is in the original cube.

Antti
