Optimization for Realistic Real-Time Rendering Method for Subsurface Scattering

Monte Carlo photon tracking is used to render translucent materials such as marble, milk, skin, etc. The technique encompasses excessive amount of subsurface scattering that is computationally expensive. Faster approaches are based on approximate models derived from observed results. While such models are efficient, they tend to miss some translucency effects in the rendered results. We present an improved approximation model for real-time rendering of materials based upon computational graphs. Excellent results are obtained improving upon the previous studies.
