speed ?
We have i.e. 1 room (inverted box) inside with we have camera, lightsource
and i.e. white sphere.
Box is covered with function with 1-3 constructions like
max(0,min(1,x+y...))
And now we add radiosity - fo reach pixel formula min(max(... must be
counted about 10..50 times depending on radiosity setting - that can
probably give 5-15% of render time lost. Hmm I guess I should just add this
minmax() function and see is speed improvment notacible :)
