abreviation for "Sub-Surface Scattering" Physical phenomena, when light hits surface some of the rays bounce right off, but some get absorbed by the material. This absorbtion is called SSS or subsurface scattering, because the rays scatter in the material. The term is used extensively in Computer graphics nowadays.
