I'm glad that POV 3.5 now supports radiosity interaction with double 
illumination. When MegaPOV came out with it's double_illumination 
keyword, I tried a similar experiement with no apparent effects from the 
radiosity.
This is just a simple test of this interaction involving a barn made 
from wood beams and fiberglass panels. Sun shines past a tall box 
casting partial light onto the barn, thus simulating scattered light inside.
Questions, Comments?

I concur with Peter. I would never have thought of that.

Beautiful effect! I'm gonna have to think of a scene for this :)

Here's a second rendering of the same scene. I placed a blue light on 
the other side of the building. It passes through a plane with a fuzzy 
chain-link fence texture. Recursion_limit 2 was used with slightly lower 
radiosity settings to try and compensate for the increased rendering 
time. It took about 44 minutes to render.
Q's, C's?

I don't know why or how you are able to continue posting images of higher
quality than most of us. These are some of the best radiosity scenes I've
seen in POV!

I'm especially impressed by the apparently small amount of time you need to
code these things. You must have a lot of experience.


Regards,
Hugo

Nice idea and image....

...but that's just a cheap trick, you have to use media (^&

More kudos for the POV Team :)

Hmm, what about a room with a dirty or frosted window, where only part 
of the light shines through directly, and the rest is scattered? Might 
be a good effect for stained-glass windows.....

Wow! This one is even greater!
I'm wishing for a wallpaper which I belive would be used for a looong time
:) (or until your next pic ;-) (How about a 1024 version for my little
desktop? ;)
What hardware do you use? (fast render?)

I just have to say it again, this is great work! :)
Keep it up!

I think I can render one next time I go on a hike (when I'm home, the 
only things to do are done through the computer).

P4 1.6 ghz, 256 megs ram

I will! Someday I'll even finish a scene!
