In this paper, we present our real-time, GPU accelerated Separable Subsurface Scattering method for interactive, Skeletal-based deformable an- imated virtual characters. Our Screen Space implementation is based on state-of-the-art methods and we propose specific algorithmic and implemen- tation extensions so that these can be employed in real-time virtual charac- ters. We have created a physically-principled real-time rendering framework, which features a series of rendering effects based on widely available open-source tools such as Open Scene Graph, C++ and GLSL so that it can be easily integrated in modern rendering engines and scene graphs via commodity graphics h/w.
