I've released another version of UVPov. Like previous versions, this one's
bound to have bugs (but hopefully nothing major) which will be fixed in
subsequent releases. ;-)
I've added a bunch of things, including:
photons are attenuated by media
sample methods 2 and 3 for media (you can still use sample method 1)
(these are uniform & adaptive sampling)
big changes to radiosity - should make radiosity scenes look better, but
might take longer to render
colored attenuation patch added
Website:
http://nathan.kopp.com/patched.htm
(To prepare you for the next version, I just rendered a scene this morning
of a dusty room (media), a clear sphere, and a spotlight, where you can see
the caustic from the sphere in the media! Still a ways to go, but so far,
so good. Plus, render times and memory consupmtion aren't horrible.)

I really like the improvements to radiosity. I once tried to do get it to use
diffuse and reserve ambient for light casting objects myself once but it came
out funny (colors inverted or some such nonsense). The higher recursion level
really improves things too - I was doing a test scene and raising the recursion
level to 4 made things visible that weren't apparent at a lower level. Overall
I'd say it's alot easier to deal with now and the results are pretty
predictable with the 3 or 4 scenes I tried it with.
Btw, my last name is Hough. :)

I'm going to take the challenge of making "the best radiosity image ever
made with povray" using the improved radiosity... :)
I have one question. I quote your example code:
if(high_quality)
// High Quality - slow rendering
ini_option "+QR"
ini_option "Preview_Start_Size=8"
ini_option "Preview_End_Size=4"
What is this "ini_option" keyword? I can't find any reference to it in
your documentation.

Got it! And already using the new media :))

I guess I'll just have to like some others... **DROOL** in anticipation

Speaking of wich, there seems to be a bug with it: after having used
these settings, I wanted to do a test render without radiosity, but with
mosaic preview and I commented out these settings and added +SP4 to the
command line options but uvpov rendered my pic one pixel at a time...

I am receiving the same error message.
