Hi Bill

That's a very interesting vase.

I just wrote a little Python script using numpy and numpy-stl to
extract the 473864 unique vertices from the STL file and store them
and the corresponding face indices in arrays in a POV-Ray .inc file.
(The number of non unique vertices in the STL file is 2811429.)

Here's a rendering with triangles, cylinders and spheres made with
data from that .inc file, showing the details around one of the
handles on the vase.
