Production Volume Rendering

Sunday, 30 July, 9:00 am - 12:15 pm, Los Angeles Convention Center, Los Angeles Convention Center - Room 408AB

Due to increasing computational power and significant advances in techniques, path tracing has now become the predominant rendering method used in movie production. Thanks to these advances, volume rendering can now take full advantage of the path-tracing revolution to create images that would not have been feasible only a few years ago. However, volume rendering also provides its own set of unique challenges that can be daunting to path-tracer developers and researchers.

This course presents the current state of the art in production volume rendering by path tracing. It presents the basic theory of volume rendering, which will lead to a comprehensive overview of different volume-integration scenarios, along with the merits and weaknesses of techniques that are useful for dealing with each scenario. The course focuses on the fundamentals of adding volume rendering to an existing path tracer, including all the practical aspects necessary for the demands of feature-film projects. And it explains proven production techniques used in lighting and integration of multi-scattered heterogeneous volumes, the most computationally demanding integration scenario.




Familiarity with rendering using physically based path tracing, including Monte Carlo integration and importance sampling.

Intended Audience

Developers and researchers who are familiar with implementing a surface path tracer and understand the basics of importance sampling.
