Abstract : We present a GPU algorithm that computes subsurface light transport in real time on arbitrary animated meshes. We evaluate both single scattering and multiple scattering, by using piecewise linear and ring-based approximations of the surface in the fragment shader. We demonstrate our technique on animated meshes at 60 fps.
