Great idea. No idea though about what could be done to pull it all together,
as you said.

My meager knowledge of the POV-Ray isosurface tells me you'd be adding a
bunch of individual "container" objects instead of accumaluating the whole
structure within a single iso.

That wouldn't be so tough I guess, collecting it all based on the container
orientation and size, since the CSG of primitives way of doing such things
is done by tying all the ends into a group too. The isosurfaces could
probably be controlled enough to make contact points since they'd be set
into 3D space as usual (whoa, am I ever making wild guesses!).

Hmmm, just had a thought. Photos of plant or tree textures might be applied
into a function as texture, maybe. You've no doubt been thinking about all
that. I just wonder if someone knows of a way to piece a whole object like a
tree into one iso. To me, that would be fascinating. All I know to do is
clump functions into a homogeneous thing :-) instead of heterogeneous.
