 RBezier
This patch is the last in my series of patches for POV-Ray. It extends POV-Ray
by ray tracing of trimmed rational Bezier surface patches using Bezier clipping
(as described by Nishita, Sederberg and Kakimoto).

I understand it, but it would be desirable to learn:
1 . Why remained unaddressed for so many years?
2 . Whether developers want to add now it in the source codes?
3 . Whether the patch if independently to try to use it will be applied?

All new is well forgotten old :)

I have a problem understanding point 3, probably my lack of grammar.

To push point 2, with the new system of source for povray 3.7, you can
have your own derivative of povray on github: with enough interests, it
might even end as a pull request.

For point 1, no clue. may be a lack of something ?

I too understood nothing that you here wrote to me.
Here patch for Povray-3.02:
ftp://atrey.karlin.mff.cuni.cz/pub/local/0rfelyus/povray-3.02/

I understood, you know it, but it isn't interesting to you?

You advise me to study C++, the source Povray-3.7 code and to take part in
development of own version?

Thanks! :)
I will better throw out the computer :)

I too wanted that my exporter was useful to someone such to what I write it,
but, it appeared, it is necessary for nobody.


Then, I won't ask you about opencl. :)

The license might be a problem, unless I misread it.
The site is cz, your email is ru, so I guess you are not the author of
the patch.

Do you have a modeler for rbezier ?
Or a killing-picture with them ? (like in "killing-application" of the
Internet bubble)

If I understand correctly this could have helped me when I made my bass  
for cutting the c-holes from the sound-box.

  You - master in C++

Povray loses on speed, exactly, because of a stubborn position........
The big problem to redistribute calculations on the videocard?

Your guitar - small that I can make.
Simply, I can't brag: God doesn't resolve!

My task - to help all!
