I had never perceived marble to be translucent until now. It is interesting to see how much more rough marble looks when it is completely opaque.

I also wonder how much more computational expensive is compared to BRDF, as we're accounting for both the current outgoing surface interaction as well as the refraction of the scattering medium.

Compared to BRDF image, the light rays in this one is much more scattered. The most noticeable illustration of their difference is the nose of the statue. We could easily recognize its translucent texture because the light hits the nose surface from the left but exits out of the screen. While in the previous image, the nose is dark on the side.
