The problem I've been having is creating a shaped density pattern for 
media.  I wanted a non-constant density that conformed to a bezier sweep 
shape.    I figured out a function using a "max" of a few hundred 
functions, but needless to say render time was tortuous.  However, using 
your method I was able to resample that function into a pigment with 
much better render time.  The attached image is the simple scene I was 
working on.  It took about 3 1/2 minutes to render using the resampled 
pigment turned function as the density function.  The original function 
took over an hour to render.   Parse time of course was much higher, but 
once the pigment was written to a file re-rendering was quite quick. 
(Incidentally the file for this pigment is 179Mb).
