Actually, my question was a little bit different. Yes, I know how radiosity
is implemented in POV, but it's still raytracing, since it relies on
shooting rays, intersecting with (mostly polynomial) objects etc. I think
Radiance uses a completely different approach. For example, in the c.g.r.r.
faq it is said that rendering speed in Radiance is not affected by the
number of objects in the scene (?!?!?). I am just curios, that's all.
