Real-Time Rendering for Multi-Layered Translucent Materials such as Human Skin under Dynamic Environment Lighting
Abstract:
Human skin is a highly scattering translucent material and is difficult to be scaled. In this paper, we combine approximation of specular reflection with subsurface scattering in the texture space and introduce the dynamic environment lighting to render the human skin to obtain a much more realistic expression. Considering lower computation and requirement for real-time, we use few spherical harmonics coefficients to represent the environment lighting approximated by the environment map. Further, by rotating the environment map, we obtain dynamic rendering effect of human skin appearance, which has a great practical value for creation of virtual character in real scene.
