Abstract
A novel approach is presented to efficiently render local subsurface scattering
effects. We introduce an importance sampling scheme for a practical subsurface
scattering model. It leads to a simple and efficient rendering algorithm, which
operates in image-space, and which is even amenable for implementation on
graphics hardware. We demonstrate the applicability of our technique to the
problem of skin rendering, for which the subsurface transport of light
typically remains local. Our implementation shows that plausible images can be
rendered interactively using hardware acceleration.
