Description

This is the same scene as this previous pic, using a tweaked lighting algorithm.

The differences are rather subtle, but look at the lighting on the various areas of the flat black surface -- the old algo was "too even", whereas the new more accurately reflects (heh) variation over the surface.

Unfortunately the tweaks also make the result much noiser, because the intensity values used don't match the PDF values as well, so it needs a lot more samples to give a smooth result... ugh, I think the basic mechanism is too flaky, gotta redesign the whole thing probably....

Wow, I have to admire your skill in 3D rendering (as I have no such skill myself). I really love your choice of subject matter. Fascinating picture.
