California Institute researchers unveil computer graphics innovations at SIGGRAPH

San Diego and Irving, CA, July 28, 2005 Nearly a dozen researchers affiliated with the California Institute for Telecommunications and Information Technology (Calit2) are headed north to Los Angeles to participate in SIGGRAPH 2005. The leading annual conference and expo about computer graphics and interactive techniques takes place July 31 to August 4 at the L.A. Convention Center. This year's event will attract a broad array of attendees, including faculty and students from UC Irvine, UC San Diego and other universities, as well as industry leaders and film-makers.

Only 98 research papers were selected from 461 submissions. Four of the accepted papers were authored or co-authored by researchers in professor Henrik Wann Jensen's Computer Graphics Lab at UCSD and will be published in the Proceedings of ACM SIGGRAPH 2005. Jensen a professor of Computer Science and Engineering in the Jacobs School of Engineering co-authored three of the papers.

"It is great that these papers got accepted for SIGGRAPH, which is the premier conference for computer graphics research," says Jensen. "The students have been working on these projects for a long time, and I am very happy that their hard work paid off."

Building on their previous work to improve the lighting of translucent objects such as skin, Jensen and Ph.D. candidate Craig Donner are now tackling the diffusion of light in multi-layered translucent materials. "We are presenting a new and efficient technique to account for diffusion in thin slabs such as a leaf where some of the light may exit the leaf rather than being completely absorbed or reflected," says Donner. "We then extended this theory and applied it to multi-layered materials such as human skin, paint or paper."

Professor Jensen who shared an Academy Award last year for a light-diffusion technique first presented at SIGGRAPH 2001 also co-authored two other new papers to be presented in Los Angeles. Together with research assi
