hey, how is all today?  

could someone tell me how much faster the different speed-up techniques
are that are used by pov-ray for ray intersection calc., in comparison
to a ray tracer not using ANY speed-up techniques. (could you please
tell me for each method seperatly!)I realize this is dependent on the
specific scene being traced, but either an average, worst/best case
senerios, or citing a specific scene would help) Is there not any
websites that have this kind of info???

also, besides for 1st hit speed-ups, and light buffers for point light
sources, are there any methods used in pov-ray besides just progressing
through a obj. tree??

thanx HUGE amounts on any replies,
