Well it was an attempt to to make a bowel in sptach (before I started
messing with lathes in povray) so it's circular with a flat bottom and as it
turns out a cone like thing in the middle. I could probably re-do it as a
union of lathes but doing csg on bicubit patches shouldn't be a problem
since most spatch models are actually unions of several bi-cubic patches.
