  Well, radiosity is the only problem that is not possible to overcome
(at least not without a complete re-design of the implementation). All
the other things are difficult, but not impossible. It has been done
before.

It's a school-project, so we think there is something to learn ... :-).

You cannot overcome most of the "problems" without rewriting large chunks of
the code.  If it was just radiosity, don't you think somebody would have
done it in the past 12 years? ;-)

What about Francois Dispot and his PVMegaPOV?

It isn't multithreaded at all...

Definitely not, but at least you can get multiple instances to
cooperate. The radiosity octree data is shared, too, so that solves a
major problem.

It might be worth a deeper look. He kept me up to date with it until
some time ago, but it was far beyond my understanding of the code to
really grasp what he was talking about.

Don't bother Peter. The enlightening advice of a guy above definitely 
killed any interest in me to continue this project. Sorry.

To make the story complete. I just got a mail from the author (shortened):

> The people in the POV-Ray newsgroup do not beleive in "patched code"  with
that result currently.

Yes, I saw that. Actually, I gave up on the idea and chose another project
instead. It was partly because they said that it was difficult, and partly
because I found it difficult to understand the code. I had no problems
understanding isolated pieces of code, but rather to get the whole picture.
