Looks interesting... well go deeper [SMILEY :-P]
Thanks

I've recently implemented this, with good results (particularly from the diffuse multiple scattering) but I'm stuck on how to numerically integrate the diffusion in order to calculate the Rd->alpha_prime table for artist-friendly parameterization.
Has anyone else implemented this? Or has read the paper and can see how to do this? I tink my lack of a mathematical background is letting me down here...
