[Radiance-general] pure monte carlo rendering tips

[Mike Martinez]

Hi folks,

I'm experimenting with irradiance cashing turned off, and would appreciate
any tips. In a test scene, I have some curious results where surfaces meet
at a corner or edge. See partial image here (note the short partitions
meeting the floor plane, you also see it along the roof structure
components):

Here are my rpict settings (most generated by rad program, overrides given
for ambient parameters):
-dp 4096 -ms 0.25 -ds .2 -dt .05 -dc .75 -dr 3 -ss 16 -st .01 -lr 12 -lw
1e-5 -ab 4 -aa 0 -av 0 0 0 -ar 800 -ad 3000 -as 1500 -ps 3 -pt .04

I'm guessing -ar doesn't matter, there may be some optimization tricks
between -ad and -as, and probably some really important variable I have
less of a grasp on...

Many thanks in advance!
