Abstract
This document describes a two-pass algorithm to compute physically accurate solutions of the global illumination in scenes including anisotropically scattering media faster than previous methods. This is achieved by combining the strengths of finite elements and Monte Carlo methods. A quick rough solution is first computed with a view independent clustered directional hierarchical method. This solution is used then by a Monte Carlo view dependent method to accelerate computation of a final accurate solution by importance sampling.
