Ugh, I don't even want to think about using 64 subpatches for creating the
mesh! That's 4X the size of the largest mesh I used. I would think that could
be very painful in terms of parsing and memory.
I'm going to move this topic over to programming, since there's some other
things I've been wanting to discuss about bicubic patches.

hehe, I remember one image I did... the entire thing was made with bicubics
(all 4x4 steps)... and there were LOTS of them :)
Take a look here if you want...

Worked fine for me... I notice that Netscape doesn't like you to click on
the address if you did it that way... you may have to copy-paste it in.
