Hi,
if I understood manual on radiosity, each time when new radiosity 
point is needed to be calculated (new value of radiosity light in given 
<x,y,z>) then always exacly COUNT samples are shooted?

How about use there variation/confidence adaptive algorithm, like this from 
focal-blur?

That way radiosity will adapt in two ways - how often new samples should be 
taken, and how exacly should they be taken.

IMHO this would in overal improve quality/speed.

For example  count 10,1000  - from 10 to 1000 samples each time when re-
calculating,  variation 1/64 confidence 0.95 - when to stop looking for new 
samples.
