That's the problem I was trying to solve with mirrors - if you place enough
mirrors that you can see key parts of the image, then the radiosity data
isn't entirely dependent on the position of the camera; it should look
decent from other angles, theoretically.

But them files will be HUGE! Even if it wouldn't work properly.

It works.

I'm not sure how the radiosity in POV-ray works, but "normal" radiosity
methods aren't camera dependant. As long as the only thing moving is the
camera, and all objects are stationary, it's easy to do real time radiosity
animation. So it should work.

I wanted to learn a bit more about how radiosity works so I found

Is this the same problem?

The shadows seem to dissapear, watch around the red box...

Maybe it's because the floor simply gets too white? As the shadows
'disappear' the floor seems to be more white than our system can display
(you know the range is clipped between 0-255) and since the shadows are
'light grey' they may turn into 'pure white' as well...?

I just tried the same animation without radiosity, and it seems fine, so
I assume it must the the radiosity causing the problems.

But it makes them look so pretty!  :(

Still not necessarely. By turning off radiosity the floor might become less
white, thus the shadows are nolonger clipped. This is just a theory. You
could try the animation with radiosity but with less strength of light.
