i3D 2010 Capstone Talk

Peter-Pike Sloan, Disney Interactive Studios

The Evolution of Precomputed Lighting for Games


Computing global illumination over a scene is a challenging problem in off-line rendering, let alone interactive applications. This talk will focus on two aspects of lighting in games: Precomputed lighting for static scenes and representations that enable dynamic characters to be plausibly illuminated as they move through the scene. We will discuss and contrast how techniques have evolved in both the academic literature and the games community, discussing the latter with detailed descriptions of how these two problems have been addressed by several recent titles. Finally, we will talk about the limitations of these approaches and open research problems in this area.


Peter-Pike Sloan recently moved to Salt Lake City to head up a research group for Disney Interactive Studios. Prior to that he spent almost 10 years at Microsoft, where he worked in the graphics research group, DirectX and on the many-core incubation team. He is interested in all areas of computer graphics, particularly interactive rendering techniques, many of his papers and talks are available online at: ppsloan.org.
