Simulating the visual appearance and lighting of human skin is a difficult task, which is addressed by researchers for several years. Because of the availability of high performance, programmable graphics boards, now it is possible to use techniques formerly only available to offline rendering. In this paper we present solutions to improve the visual quality of skin by enhancing such techniques to real-time application. Furthermore dynamic properties like aging and emotional changes in the appearance of a face like blushing and weeping are introduced to obtain convincing results at interactive frame rates for immersive virtual worlds.
