We
propose a novel skin shader which translates the simulation of
subsurface scattering from texture space to a screen-space diffusion
approximation. It naturally scales well while maintaining a
perceptually plausible result. This technique allows us to ensure
real-time performance even when several characters may appear on screen
at the same time. The visual realism of the resulting images is
validated using a subjective psychophysical preference experiment. Our
results show that, independent of distance and light position, the
images rendered using our novel shader have as high visual realism as a
previously developed physically-based shader.
A very efficient implementation is described in the first book of the GPU Pro series [Buy the book!]
