Have any of you ingenious (and I mean that) programmers ever looked into
incorporating what is called the Metropolis Light Transport algorithms into
POVRay. This looks like a great method of adding more accurate radiosity
rendering to the already #1 raytracer.

I forgot to give a URL where you can find out about Metropolis if you don't
know. Find it at http://graphics.stanford.edu/papers/metro/

It looks very interesting, but it's unfortunately beyond my skills to
code this sort of thing. Perhaps someone else is able and interested?
The demo images do look nice.
I wonder if photon mapping would be of any use to this technique?

Nathan said it wouldn't help MegaPOV's current radiosity.

Actually, I said that theoretically it should be able to help the current
radiosity, but I have been unsuccessful in implementing that part (the
global photon stuff, in case people happen to be looking at the source
code).
I'll have to look more closely at this new light transport model to find out
if it compliments photons and radiosity or replaces them. The sample images
look pretty neat, though. :-)

Replaces them. Its main flaw is it's not very useful in programs that want
to generate pixels in a predefined order, as POV is wont to do.

These are my opinions. I do NOT speak for the POV-Team.
