Hello,

One year ago, I wrote a patch for PoV 3.1g that implements a stochastic
ray-tracing technique using hemisphere sampling (Monte Carlo
integration) to compute global illumination.  This technique is a bit
different than the monte carlo technique already existant in PoV, but it
gives pretty nice, more "radiosity-esque" and interesting results.  In
fact, the effect of inter-diffuse reflection is much more realistic and
distinctly visible.  The hemisphere sampling distribution can be
computed by 8 methods, each of them giving differents rendering results.
The complete illustrated html documentation, the source code, and a
patched WinPoV executable can be downloadable from my web page :

Mr Kopp (a.k.a. Nathan), if you think this patch is interesting enough
to become a part of the next MegaPoV release, feel free to include it.
Yes, it sounds like an authorization... ;o)
In a near future, I will probably improve it by adding a few more
options.

Best regards,
