Just look at this http://luxlab.com/tmp/rad_brilliance.gif
The radiosity rays definitely have a direction. The algorithm may
be limited only to Lambertian surfaces because of difficult integrals
or something.

Equivalent ambient source has the same dimensions as the light source.
Just look up "equivalent" in the images group. I guess I did the impossible.
I marked it as experimental as I knew this was pushing the limits of what
POV-Ray can do. Brilliance is the limit :)
