I seem to recall hearing that povray's built in pigment functions (like
crackle, bozo, etc...) take a long time in generating isosurfaces. I am not
an isosurface pro though, i've only started playing with them recently like
you. I could be wrong, and the exact opposite could be true about pigment
functions! It would be nice to here someone else say what the story is.
Someone like Tor Olav, with his amazing isosurface experience, would
probably know.

sorry i couldn't be any real help.
