This tutorial survey paper reviews several different models for light interaction with volume
densities of absorbing, glowing, reflecting, and/or scattering material. They are, in order of …

The interaction of light and matter in the world surrounding us is of striking complexity and
beauty. Since the very beginning of computer graphics, adequate modelling of these …

This paper presents a new method for computing global illumination in scenes with
participating media. The method is based on bidirectional Monte Carlo ray tracing and uses …

Develo** a visually convincing model of fire, smoke, and other gaseous phenomena is
among the most difficult and attractive problems in computer graphics. We have created new …

Multiple scattering in participating media is generally a complex phenomenon. In the limit of
an optically thick medium, ie, when the mean free path of each photon is much smaller than …

In this paper we show how bidirectional path tracing can be extended to handle global
illumination effects due to participating media. The resulting image-based algorithm is …

Algorithms for image synthesis render photo-realistic imagery, given the description of a
scene. Physically based rendering specifically stresses the physical correctness of the …

In this paper we show how Metropolis Light Transport can be extended both in the
underlying theoretical framework and the algorithmic implementation to incorporate …

Rendering participating media is important for a number of domains, ranging from
commercial applications (entertainment, virtual reality) to simulation systems (driving, flying …

Direct volume rendering is a commonly used technique in visualization applications. Many
of these applications require sophisticated shading models to capture subtle lighting effects …
