Upper left: image in question
Upper right: similar issue on POV sample scene with 'error_bound' = 0.1
Lower left: 'error_bound' = 1.8 will smooth artifacts but has some funny
self-illumination going on
Lower right: 'error_bound' = 0.01 will work OK, after many more hours spent
rendering...
(All three cases use 'count' = 800)
So it's about balancing 'error_bound' vs. render time.
Note, if you use textures (pigment and normal maps), radiosity artifacts can
even add to some nice result.
