Spectral and Decomposition Tracking for Rendering Heterogeneous Volumes

SIGGRAPH 2017

Peter Kutz, Ralf Habel, Yining Karl Li, Jan Novák

We present two complementary, unbiased techniques for sampling free paths in heterogeneous, chromatic participating media: decomposition tracking for reducing costs and spectral tracking for reducing variance. We formulate our new techniques in the context of a mathematical framework novel to computer graphics, derived directly from the radiative transfer equation.
