I once made a macro that generates a mesh for
a bezier patch.

(But I don't know if it is this macro ABX is
referring to.)

If you want to try it, you must look for
the BezierPatchFunction() macro in this post:

http://news.povray.org/povray.text.scene-files/22698/157269/

(This macro is not limited to making functions
for bicubuc patches from a 4x4 grid of points.
It can take any number of control points in
both directions.)

You will also need either one of Ingo's
"Meshmerizing Mesh Maker Macros" or one of my
old mesh macros. (Ingo's macros are nicely
documented. Mine are not.)

You can find Ingo's mesh web page here:

If you want to use my mesh macros, you must
look for WriteParamMesh() or ParametricMesh()
in this post:
