I don't see why not.

Ben states that they were unable to scan the interior of the vessel, due to the
limitations of the structured light scanning instrumentation.

They also play around a bit with the mesh and some primitives using Blender.

One very interesting point that brought up is the seemingly anomalous lack of
accuracy in the lug handle holes.   Ben points out that, given there are a large
number of examples of vessels that have no holes whatsoever, that the vase may
have been manufactured without holes, and someone (less skilled) added the holes
later.

Apparently there has been some small bit of controversy between the two main
post-metrology analysts regarding reference points, proportions, and what is
real regarding various dimensions lines and ratios.

It might be interesting to develop a parameterized vessel composed entirely of
primitives as a sort of playground, that can them be exported as a mesh for
comparison in CloudCompare, Polyworks, or other more sophisticated software.

Has anyone opened it in MeshLab to see what sorts of measurement and analysis
tools are available there?
