Volume raycasting techniques are important for both visual arts and visualization. They
allow an efficient generation of visual effects and the visualization of scientific data obtained …

We present a step toward interactive physics-based modeling of terrains. A terrain,
composed of layers of materials, is edited with interactive modeling tools built upon different …

Example-based texture synthesis algorithms have gained widespread popularity for their
ability to take a single input image and create a perceptually similar non-periodic texture …

Clouds play an important role for creating realistic images of outdoor scenes. In order to
generate realistic clouds, many methods have been developed for modeling and animating …

Aging phenomena often play a key role in realistic rendering: excepting when the desired
result is specifically a brand-new virtual object, their absence can lead to non-realistic …

Lacunarity is a measure of how data fills space. It complements fractal dimension, which
measures how much space is filled. Many researchers use the gliding box algorithm to …

In this article we present a novel radiance caching method for efficiently rendering
participating media using Monte Carlo ray tracing. Our method handles all types of light …

We present a novel method for procedurally modeling large complex shapes. Our approach
is general-purpose and takes as input any 3D polyhedral model provided by a user. The …

A good random number generator is essential for many graphics applications. As more such
applications move onto parallel processing, it is vital that a good parallel random number …

Existing solid texture synthesis algorithms generate a full volume of color content from a set
of 2D example images. We introduce a new algorithm with the unique ability to restrict …
