The answer to this question is probably going to go way
over my head, but here goes...
I'm trying to figure out just how these bicubics work.
The pov docs say I should use a modeller, but I wanted to 
try my luck at animating a few patches together, in harmony
using variables for the control points. However, only the 
corners(as far as I know) are stable, that is to say each
corner actually resides at the point in space indicated by its
vector. 
Lets say I have 2 patches side by side, each patch is a square,
together forming a rectangle. When I pull on a corner the middle
seam comes apart.
So, the question is: What frightening math equation do I need to
know and love in order to keep those seams together.


Note: I am mathematically challenged...please explain as though
you are speaking to a moron, because you are. :-)
