Real-time and interactive rendering for translucent materials such as human skin

Abstract

To synthesize a realistic human animation using computer graphics, it is necessary to simulate subsurface scattering inside a human skin. We have developed a curvature-dependent reflectance functions (CDRF) which mimics the presence of a subsurface scattering effect. In this approach, we provide only a single parameter that represents the intensity of incident light scattering in a translucent material. We implemented our algorithm as a hardware-accelerated real-time renderer with a HLSL pixel shader. This approach is easily implementable on the GPU and does not require any complicated pre-processing and multi-pass rendering as is often the case in this area of research. © 2011 Springer-Verlag.
