This has been discussed several times before. I think that someone has
even done a POV-library for C++ (that can even read pov-files).
It has, however, never really hit the spot for one reason or another.
What stops you making a program in C++ that just outputs a pov-file and
calls povray to render it? It shouldn't be hard.

Well, that's almost exactly what I already done... I actually made a program
that renders a OpenGL-Preview scene and I check the movements, the emplacement
of objects, etc... and when I'm satisfied I can make it write a file on disk and
call povray for the job... I was thinking of getting the POV-Ray source file
and include it in my application so the render could be drawn for example over
the opengl preview... etc...
Thanks,
Simon

1) You can't do that. It's expressly prohibited in povlegal.txt.
2) You can call povray as an external program and get the image into your
application using an API in the Windows version of povray. Moray uses this
technique.

Technically, it's only prohibited if you wanted to distribute the resulting
application. If it's just for your personal use, I'm pretty sure it's okay.
I'm not speaking officially, of course.

I somehow completely miss your point...
Do you mean use Python for the framework/library, or for the scene
description language?
If for the scene description language, what would be the benefits? Some
of the problems would be: forcing a language not designed for scene
description to be a scene description language, forcing everyone who
uses POV to relearn the language, making all the sample code, scene
files, includes, and macros out there completely useless, making POV
more difficult to learn, etc, etc, etc.
If for the programmer's framework, I have already suggested Java, which
probably has more people with experience in it, and has many
similarities to C++ which would make a port easier.
And what does this have to do with the definition of a function?

Abstract for povlegal.txt:
/*
PERMITTED MODIFICATION AND CUSTOM VERSIONS
Although the full source code for POV-Ray is distributed, there
are strict rules for the use of the source code. The source
distribution is provided to;
1) promote the porting of POV-Ray to
hardware and operating systems which the POV-Team cannot support.
2) promote experimentation and development of new features to the
core code which might eventually be incorporated into the official
version.
3) provide insight into the inner workings of the
program for educational purposes.
*/
Take a look at number 2... development of new features to the core... such as
instant preview...
/*
The user is granted the privilege to modify and compile the source
code for their own personal use in any fashion they see fit. What
you do with the software in your own home is your business.
*/
There! Did I say I would do it for personnal purpose? However, if my work is
good, I'm sure I can manage to put it at povray.org in the download section as a
plugin, patch, enhancer, etc...

I wont... I'd like my program to be fully independant, don't need any other
installation, except OpenGL drivers for accel, etc...
Next time, read more carefully!

You are not allowed to use POV source code in other programs. Perhaps
*you* should read more carefully...especially the part starting with:
"A "custom version" is defined as a fully functional version of POV-
Ray with all existing features intact. ANY OTHER USE OF ANY POV-
Ray SOURCE CODE IS EXPRESSLY PROHIBITED. The POV-Team does not
license source code for any use outside POV-Ray. No portion of the
POV-Ray source code may be incorporated into another program
unless it is clearly a custom version of POV-Ray that includes all
of the basic functions of POV-Ray."
If all you are doing is adding an OpenGL rendering mode to POV-Ray, you
should be fine, but distributing a different program that uses POV
source code is not allowed.

The key here is the word 'distributing'.

Python doesn't qualify, as it requires indenting, to which some object
