Research on Scattering

Hey Guys, just wanted to point this speech out.
These guys are doing very nice work - hope many renderers pick this thing up.

Light Diffusion in Multi-Layered Translucent Materials

Paper: A Spectral BSSRDF for Shading Human Skin

oh my skin is getting oily...

Nice. That is some serious maths...

What I got from the presentation was that they ran a simulation on the multi-layered material to derive a Transmittance profile, and that that profile is geometry independent? So for speed, they assume that the material is applied to a thin flat surface, and because the sub-surface scattering occurs within a very thin layer of an object, the actual form of the geometry is considered negligible?

I could be way off?
