I'm interested in knowing more about how bicubic patches work, so that I can
maybe make some macros that can extent the things possible to do with
bicubic patches.

Here's a challenge:

Make a macro takes 16 points as input and then creates a mesh similar to the
corresponding bicubic patch.

Oh, well, I probably can't expect that anyone do that just because I ask,
but then I at least hope someone can point me to resources that contains
enough information that I will be able to do it myself.
