Yeah, but the problem is figuring out what that means. :-)
It looks simple, but I can't translate it into an algorithm, and I have 
only a slight idea what u() is supposed to do.

Does it require that the density field be converted to a voxel image? I 
hope not...but if it requires multiple passes that can't be done at 
once, I don't see a way around it.
