Okay thanks for the clarification. I've used the macro often to make
polygonal (I guess they ain't circles) cross sections but I guess I hadn't
peeked under the hood as much as I should have.

I guess I'm thinking about the ability to *change* the closed-loop spline
for the section as you go along the path.


I am thinking of making a head +neck + torso.   Imagine a slice at the nose,
at the chin, at the neck, at the pecs, at the belt.  You could define a
closed loop macro of five points (or ten) at each slice.   Then, if one
merely animates the spline which forms the spine, you've got a completely
animatable character created purely in povray.  This is my dream.

I might be able to program this myself, but I have made gross errors when
programming such a thing.

Thanks.
