We are working on a project using POV-Ray at university of Bonn. As we have
to use the POV-Ray programming style guides, we would like to know when the
new version (4.0) will be released and if the programming style will be
changed (real classes etc.).
For our implementation we have to use trimmed NURBS surfaces; is there
anyone out there working on this?

POV-Ray v4.0 is still in the planning stages and the design decisions that
will be used have not been finalized. It will be many months before details
of its design are released to the public and quite some time after that before
it is ready for final release. The only thing the POV-Team will say right
now is that it will be rewritten in c++.

None that I am aware of. NURBS surfaces are generally considered to be useful
in Modelling software and usually tesselated/subdivided into triangles before
being used by raytracing software. It my understanding that POV-Ray will likely
never have direct support for rending of NURBS surfaces.

I think someone made a macro to render nurbs as parametric surface or as
mesh.

There is no official release schedule or anything like that and the POV-Team
does not disclose internal schedules in general. That said, while POV-Ray
4.0 will be rewritten in C++, some fundamental aspects of ray-tracing
enforce a certain class structure which at the very least implies all
objects have methods which provide what is currently provided as part of
"Method_Struct" in frame.h .
May I ask which department/professor is leading the research? If you don't
want to post this here, you may also contact me at

Something in the back of my fuzzy little brain recalls something like that but
it still does not imply -direct- support for the rendering of NURBS surfaces
in POV-Ray :)

Ups, "every", of course :-)
