Importance sampling of area lights in participating media

Published: 07 August 2011 Publication History

Abstract

We focus on the problem of single scattering in homogeneous volumes and develop a new importance sampling technique that avoids the singularity near point light sources. We then generalize our method to area lights of arbitrary shapes.
