ehhhh :) no comment... :)

Nope.
I am writing my own GI renderer and studied radiosity/monte carlo/irradiance caching
over
years.... then tried to look how POV is doing that.

When I saw the GI code in POVRAY, I sat down and started to cry :)
Many bugs! Bugs meant by misunderstanding light theory and many nifty
"methods" of coping with "crossing 1's value".

I know the code is working, but is highly limited in some areas eg. light is not so
well
propagating in corridors, tunnels etc. due to many limits bound on GI values during
caching and mixing with diffuse coefficients - no matter how many GI bounces you
gave in rendering settings.

I think that it is the time to redesign radiosity code, there are so many new theories
and
algos now... somebody could boost POV in XXI century.
