Yea, but moreso for more complex transformations. I know that a lot can be done
with CSG, but I was thinking of something more along the lines of the
following:

This was done in Rhino and exported to POV. The rough equivilant in POV (if we
had this feature) would be:

sphere {0,18
 scale_map y{
  [0.0   <1.0,       1.0>]
  [2/36  <5.5/8,     6.5/8>]
  [7/36  <5.5/14,    7/14>]
  [14/36 <14.5/17.5, 13/17.5>]
  [18/36 <16.5/18,   19.5/18>]
  [22/36 <15.5/17.5, 23/17.5>]
  [29/36 <8/14,      12/14>]
  [34/36 <6/8,       7/8>]
  [1.0   <1.0,       1.0>]
 }
}
