Hey Robert. Yeah, It can deal with varying sphere sizes. At first I
thought voro++ was mangling the order of my points, but this does not
appear to be the case. This means I can maintain a list of sphere sizes
(or just use the same random seed) in-POV without having to export the
radii to voro++. Other particle-specific data can be maintained as well.

The placement of non-spherical objects is beyond the scope of the
current setup, though some interesting things will be possible. For
instance, after a mass of evenly distributed cells is produced, an
algorithm can be built to "walk" through the point/neighbor lists, with
entries destroyed each time a cell is used. This should allow one to
place non-intersecting cylindrical objects or sphere_sweeps within the
cell mass.
