Thanks, that was what I meant.  :o)
I tried averaging pigments in a circle formation but it's not smooth enough
for isosurfaces. I hoped there was a mathematical way to blob pigments ala
other shapes in isosurfaces.. I think it would be very useful.. Imagine a 3d
pigment taken from an object-pattern (though, until now object patterns are
only 2d..)  Then we could describe an object with ordinary POV primitives,
make it a 3d pattern and blob that shape in an isosurface.
