Fast realtime subsurface scattering skin Rendering

Through the vertex texture fetch (VTF) technology of sm3.0, the subsurface scattering of each vertex is calculated in the vertex shader, which greatly improves the performance, in the 1024x768 running window, open the 4x anti-aliasing feature. The FPS can also be stable at around 60 frames, and the rendering effect is also acceptable. Below is:

Because subsurface scattering is used hereAlgorithmThe parameters used are calculated in real time. Therefore, they are applicable to any dynamic scenario and animation model. Therefore, they can achieve real-time subsurface Scattering Effects on any deformed objects.
