ingo, thanks for thinking this through with me.  First of all upon looking at
your google code site (but not yet d/ling any files) I'm wondering which include
or routine it would be. I want to animate the splines, then generate meshes
inside povray.  And as you describe it, how is the transition from material that
is, say, the seat of pants, to to the upper leg?

I've got a macro where I modified Mike's code to take any arbitrary sectioning
shape-- superellipsoid, cube, squashed cylinder-- instead of a circle, as it
creates the mesh along the backbone. With it, I've made a mesh2 shape that
vaguely represents top of head to bottom of torso, it's just a "two hole"
structure.  I'm now thinking about the transition around the seat to sleeves.
