Here's a new version of the NURBS include file: NURBS_29.inc
(The remapping macros were renamed and a couple of errors within them were
fixed.)

I hope you are able to use the macros.
If you have any question about them, then just post them
and I'll try to find time to answer you.

Greetings to you too Thorsten.

Thank you for your kind offer :)
This is what I wanted to get form your NURBS macros:
a) The actual surface... preferable as
b) mesh or mesh2, writeable to file to include it in a complex scene later.
I'm was thinking of architectural things and (space-) shiphulls :)
But it seems I'm have to learn more about two things
a) POV-Ray and
b) Math
first :)
Thank you for having developed NURBS for POV (as far as I understand
them) :)
Greetings :))
