8.45-9.45 Invited Talk:
"Artificial Animals and Humans: From Physics to Intelligence" The confluence of virtual reality and artificial life, an emerging discipline that spans the computational and biological sciences, has yielded synthetic worlds inhabited by realistic, artificial flora and fauna. Artificial animals are complex synthetic organisms that possess functional biomechanical bodies, perceptual sensors, and brains with locomotion, perception, behavior, learning, and cognition centers. Artificial humans and lower animals are of interest in computer graphics because they are self-animating graphical characters that can dramatically advance the state of the art of production animation and interactive game technologies. More broadly, these biomimetic autonomous agents in their realistic virtual worlds also foster deeper, computationally oriented insights into natural living systems. Speaker Bio: Demetri Terzopoulos holds the Lucy and Henry Moses Professorship in Science at New York University and is Professor of Computer Science and Mathematics at NYU's Courant Institute. He is also affiliated with the University of Toronto, where he is Professor of Computer Science and Professor of Electrical and Computer Engineering. He graduated from McGill University and received the PhD degree (EECS) from MIT in 1984. His published work comprises hundreds of research papers and several volumes, primarily in computer graphics, computer vision, medical imaging, computer-aided design, and artificial intelligence/life. A Fellow of the IEEE, Professor Terzopoulos has been a Killam Fellow of the Canada Council for the Arts, a Steacie Fellow of the Natural Sciences and Engineering Research Council of Canada, a Fellow of the Canadian Institute for Advanced Research and a Fellow at UCLA's Institute for Pure and Applied Mathematics. His many honors include computer graphics awards from Ars Electronica, NICOGRAPH, Computers and Graphics, and the International Digital Media Foundation. He is co-chair of the 2005 ACM SIGGRAPH/Eurographics Symposium on Computer Animation. Professor Terzopoulos is a member of the European Academy of Sciences. 9.45-11.00 Paper Session 1: Facial Expression (Session Chair: Nadia Magnenat-Thalmann) Image-Driven Re-targeting and Relighting of Facial

Screentoons International, Leonard Quam, Vindigo Until recently mobile platforms, with their tiny monochrome displays, slow processors, and closed development environments did not provide an interesting graphics platform. This has changed: high-quality color displays are supported by fast CPUs and in some cases by dedicated graphics hardware, and open development platforms with recently standardized mobile 3D APIs provide very interesting and quickly developing graphics platforms. Our panel has representatives from all aspects of the mobile graphics world. Brief introductory presentations by the panelists are followed by an interactive discussion on the current state and future of mobile graphics.

8.45-9.45 Invited Talk:
"Ray Tracing on the Desktop: When and How?" For some niche applications such as large-scale data visualization, parallel software ray tracers are already much faster than the most optimized GPU implementations. However, GPU programs are the only viable choice for most interactive applications. There are three clear possibilities for the future of graphics on the desktop. First is a continuation of z-buffer based GPUs. Second is an emergence of interactive ray tracing running on multicore CPUs. Third is ray tracing using custom hardware (ASIC). This talk examines trends in hardware and application data and argues that ray tracing using custom hardware is the likely winner, and outlines the research problems that will need to be overcome for such an outcome. Speaker Bio: Peter Shirley is an associate professor in the School of Computing at the University of Utah. He has a B.A. in physics from Reed College and a Ph.D. in computer science from the University of Illinois at Urbana-Champaign. He spent four years as an assistant professor at Indiana University and two years as a visiting assistant professor at the Cornell Program of Computer Graphics before moving to Utah. His professional interests include interactive and realistic rendering, statistical computing, visualization, and immersive environments. 9.45-11.00 Paper Session 9: Images and Textures (Session Chair: Xiaoyang Mao) Spatial Partitioning of Geometry Images Using
