Not necessarily if the vertices around the joint moves by an average between
the two bones. I think.

That sounds interesting. I'm curious, how have you managed to get around the
topology problem with bicubic patches? Triangular bicubic patches are not
supported in POV-Ray, and I've never seen three bicubic patches sharing one
corner fit seamlessly together. Well, seamlessly I have seen, but not with a
completely smooth surface...

I'd be interested in hearing more about your plans and the format.
