Why is the limit on radiosity samples 1600?  I think
both my computer and patience can handle much more than
that.

Creating a set of good samples is more difficult than it seems. I created a
set that enables 32000 samples, but someone told me that the distribution
wasn't isotropic. When I asked what would be the meaning of isotropic in
this matter, I never got a reply!

so: WHAT WOULD BE AN ISOTROPIC DISTRIBUTION?????

Evenly spaced, with no clumping.

Maybe it would be a good idea to actually read the replies you get...

I can't connect to my computer where I've stored "my" 32000 set, but now I
understand what you're saying and if I remember correctly the 32000 set is
perfectly all right because the densities of the distribution is like the
original 1600 set.

In the same thread I got confused about how radiosity works with the samples
set. It was said that no matter the error_bound and other vars, the amount
of samples taken always equals count. I'm still confused! What's the use of
the other vars if count is the only var that matters?
