Monte Carlo sampling setting

radiance-general

Hi Greg,

I need a test with true Monte Carlo sampling (in the contrary as many earlier requests, I need as much variance in different runs of rpiece as possible).
I assume rpiece takes the same default values as rpict (?)

"rpict -defaults" gives:

-u- # correlated quasi-Monte Carlo sampling

It is not clear to me how to set true Monte Carlo sampling on.

-u+ ?

Cheers,

Yes and yes. You can use the -u+ option in rpiece, along with all the other rpict options. I recommend setting "-ps 1" as well for pure MC.
