Hi Nicola,

Thanks for writing!  There's work being done on unstructured meshes
right now, and the timeline is that we're aiming to have support for
tetrahedra, hexahedra, and wedges by the end of May.  Jill Naiman and
I are sprinting on this the next couple weeks.  That doesn't *quite*
get you to what you're looking for, but it's a slightly different
situation for voronoi tesselations anyway, since they are both more
complex and simpler to define.

What would be possible, right now, would be to load in the data as
particles, visualize it (by over-refining the mesh by a good amount
and using nearest-neighbor mesh deposition), and if you have the
volumes stored in advance, do quantitative analysis.  Computing the
volumes on the fly isn't yet possible (but could be implemented) and
hopefully in the next couple weeks it'll be a lot easier to make
visualizations without over-refining the mesh.

Please feel free to stop by IRC sometime to chat more about this, and
if you are able to give a try to loading in as particles, let us know
how that goes.
