We address the problem of modeling and rendering granular materials—such as large
structures made of sand, snow, or sugar—where an aggregate object is composed of many …

We introduce a non-exponential radiative framework that takes into account the local spatial
correlation of scattering particles in a medium. Most previous works in graphics have …

Sub‐surface scattering is always an important feature in translucent material rendering.
When light travels through optically thick media, its transport within the medium can be …

Previous proposals to permit nonexponential free-path statistics in radiative transfer have
not included support for volume and boundary sources that are spatially uncorrelated from …

When lifting the assumption of spatially-independent scattering centers in classical linear
transport theory, collision rate is no longer proportional to angular flux/radiance because the …

This paper introduces a mathematical approach that allows one to numerically solve the
nonclassical transport equation in a deterministic fashion using classical numerical …

An improved modification of the Spectral Approach (SA) used for approximating the
nonclassical neutral particle transport equation is described in this work. The term “Spectral” …

Presented here is the application of the spherical harmonic expansion to the nonclassical
transport equation to derive a system of equations for the nonclassical flux moments, namely …

We show that several diffusion-based approximations (classical diffusion or SP_1, SP_2,
SP_3) to the linear Boltzmann equation can (for an infinite, homogeneous medium) be …

We report on a novel analytical solution of the three-dimensional radiative transport
equation for the case of an infinitely extended anisotropically scattering medium that is …
