I'd like to be able to do this or similar:
http://home.online.no/~t-o-k/POV-Ray_Images/NURBS_Bivariate.jpg
Is this done with a texture?
UV mapping? (my best guess)
Thanks to anyone who can give me some tips or a full-fledged solution.
Bill

Tor Olav Kristensen used a nurb macro of his making that create a mesh
that can be UV mapped.
That image is an example of that macro.

OK, I'll have to learn some about this NURBS spline.
I got a simple grid made, and image-mapped it, and got something close.
Since it's not NURBS, the extreme curvatures really distort the lines
and text, but I get the idea.
Granted, my layered texturing is BAAAAD, but it's OK for a WIP.
See in p.b.images

So, I wrapped a grid around some items, and the graphic file obviously
gets distorted in places.
Is there a way to create a object whose length and width vary as the
inverse of the mapping transformation? I'd probably be able to puzzle
this out in 2d, but the 3D solution is a little intimidating.
I know squat about NURBS, and this would a good first approximation to
getting the grid to retain most of its shape.
