Production Volume Rendering I & II (siggraph 2011)

Production Volume Rendering I & II (siggraph 2011)

Computer generated volumetric elements such as clouds, fire, and whitewater, are becoming
commonplace in movie production. The goal of this course is to familiarize attendees with the
technology behind these effects. The presenters in this course have experience with and have authored
proprietary volumetrics systems.
We present the specific tools developed at Double Negative, Weta Digital, Sony Imageworks, Rhythm &
Hues, and Side Effects Software. The production system presentations will delve into development
history, how the tools are used by artists, and the strengths and weaknesses of the software. Specific
focus will be given to the approaches taken in tackling efficient data structures, shading architecture,
volume modeling techniques, light scattering, and motion blurring.
