16. Practical Global Illumination With Irradiance Caching

Half-Day, 8:30 am - 12:15 pm
Level: Intermediate
Room 9

A practical guide to implementing irradiance caching algorithms to efficiently render flawless images featuring global illumination. The course summarizes recent research advances related to irradiance caching: caching on glossy surfaces, temporal caching, acceleration through GPU implementation, and irradiance decomposition.


Basic understanding of rendering, ray tracing in particular. Familiarity with global illumination concepts is useful but not required.

Intended Audience

Anyone interested in making an irradiance caching implementation that reliably renders artifact-free images. Researchers and industrial developers interested in recent speed and quality improvements of global illumination with irradiance caching.
