Real-Time Approximate Subsurface Scattering on Graphics Hardware

This paper presents an image-space approximation technique for real-time subsurface scattering. We first create transmitted irradiance samples on shadow maps and then estimate single scattering efficiently using a method similar to shadow mapping, with adaptive deterministic sampling. We incorporate this single-scattering with a recently proposed technique for multiple scattering. We demonstrate that our technique produces high-quality images of animated scenes. We archived hundreds of frames per second on graphics hardware without lengthy preprocessing.
