The wide adoption of path‐tracing algorithms in high‐end realistic rendering has stimulated
many diverse research initiatives. In this paper we present a coherent survey of methods that …

We present two contributions to the area of volumetric rendering. We develop a novel,
comprehensive theory of volumetric radiance estimation that leads to several new insights …

We present an efficient many-light algorithm for simulating indirect illumination in, and from,
participating media. Instead of creating discrete virtual point lights (VPLs) at vertices of …

We develop a theory of volumetric density estimation which generalizes prior photon point
(0D) and beam (1D) approaches to a broader class of estimators using" n D" samples along …

46: 2• ** Deng, Shaojie Jiao, Benedikt Bitterli, and Wojciech Jarosz 1) suffer from
singularities, and 2) require at least two bounces in the medium past any surface, relegating …

Photon-density estimation techniques are a popular choice for simulating light transport in
scenes with complicated geometry and materials. This class of algorithms can be used to …

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 …

Abstract Central to all Monte Carlo-based rendering algorithms is the construction of light
transport paths from the light sources to the eye. Existing rendering approaches sample path …

We introduce a refractive radiative transfer equation to the graphics community for the
physically based rendering of participating media that have a spatially varying index of …

In this work, we introduce a novel algorithm for transient rendering in participating media.
Our method is consistent, robust and is able to generate animations of time‐resolved light …
