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 third edition of this classic tutorial and reference on procedural texturing and modeling
is thoroughly updated to meet the needs of today's 3D graphics professionals and students …

We present a method for rendering scenes with fine detail via an object called a texel, a
rendering primitive inspired by volume densities mixed with anisotropic lighting models. This …

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 …

This paper presents a ray tracing algorithm for rendering 3D scalar fields. An illumination
model is developed in which the field is characterized as a varying density emittter with a …

This paper proposes a simple and computationally inexpensive method for animation of
clouds. The cloud evolution is simulated using cellular automaton that simplifies the …

A method to display the earth as viewed from outer space (or a spaceship) is proposed. The
intention of the paper is application to space flight simulators (eg, reentry to the atmosphere) …

Methods to display realistic clouds are proposed. To display realistic images, a precise
shading model is required: two components should be considered. One is multiple …

The zonal method for calculating radiative transfer in the presence of a participating medium
is applied to the generation of realistic synthetic images. The method generalizes the …

The need to visualize huge amounts of numerical data is exemplified in the field of
meteorology, where measurements of many atmospheric parameters are routinely taken …
