A Rapid Hierarchical Rendering Technique for Translucent Materials

Abstract

In this project, we have implemented the hierarchical BSSRDF evaluation technique introduced by Jensen and Buhler [2002]. This method is based on an efficient decoupling of the computation of irradiance at the surface from the evaluation of scattering inside a translucent material. The computation of irradiance is performed by an extension of pbrt, while the evaluation of subsurface scattering is based on an implementation of the dipole diffusion approximation introduced by Jensen et al. [2001].
