Much faster than other methods that simulate multiple scattering. POV 
doesn't simulate multiple scattering, for speed reasons.

From what I can tell at a glance, this paper involves a preprocessing 
computation step similar to media photons or radiosity, followed by 
something similar to a standard raytracing media algorithm at render 
time. It is most likely quite a bit slower than the equivalent in POV, 
though more accurate.
