I have learned myself how to handcode bicubic patches that fits seamlessly
together. However, I never get the result I want when I try to make a patch
where two of the corners lie in the same point.

Say I want to make a unit-sphere made of 8 bicubic patches. Could you show
me what one of those patches would look like in POV-code? It doesn't have to
be a 100% perfect sphere, but I don't want any "folds" anywhere.
