Abstract: Summary We present techniques that enhance global illumination algorithms by incorporating the effects of participating media. Instead of ray marching we use a sophisticated Monte Carlo method for the realization of propagation events and transmittance estimations. The presented techniques lead to unbiased estimators of the light transport equation with participating media.
