This paper presents an analytical subsurface-scattering model and effective BRDF for forward-scattering media. The model is not based on diffusion theory, but follows from the functional integral formulation of radiative transport. It handles the full behavior from unscattered straight-line propagation to the fully diffusive limit.

This paper presents an efficient method for rendering explosions with self-illumination and self-shadows by converting the volumetric lighting data into many point lights, and it introduces lighting-grid hierarchy as a novel solution to the many-lights problem that is temporally stable and provides superior performance by precomputing shadows.

This paper presents two unbiased techniques for sampling free paths in heterogeneous, chromatic participating media. It formulates new techniques in the context of a mathematical framework novel to computer graphics, derived directly from the radiative transfer equation.

This generalized theory of volumetric-density estimation shows that photon points and beams are just special cases of a more general class of nD estimators. Implementations of estimators predicted by the theory outperform state-of-the-art volumetric photon mapping techniques by a factor of 2-40x.
