Abstract:
Recent decades have seen the dramatic rise of computer graphics and physics-based animation---from early algorithms to sophisticated software systems and parallel architectures.  Unfortunately, as we race toward highly interactive and realistic visual experiences, it is becoming obvious that something is still lacking: realistic sound.  For starters, most current physics simulators are inherently silent, so sounds are added as afterthoughts often having little to do with the animated geometry or physics.  Compared to computer graphics, algorithms for rendering realistic and synchronized sounds for virtual objects are still in their infancy.  My talk will cover the challenges of physics-based sound rendering, and discuss recent progress on sound models for contacting rigid bodies, the noisy nonlinear vibrations of thin shells, familiar splashing and gurgling sounds of water, and a few brittle objects smashed along the way.

Biography:
Doug L. James is a tenured professor of Computer Science at Cornell University. He holds three degrees in applied mathematics, including a Ph.D. from the University of British Columbia in 2001 under the guidance of Dinesh Pai.  In 2002 he joined the School of Computer Science at Carnegie Mellon University as an Assistant Professor, then in 2006 he became an Associate Professor of Computer Science at Cornell University. His research interests are computer graphics, physically based animation, reduced-order physics models, and multi-sensory physics applications such as sound rendering and haptic force-feedback rendering. Doug is a National Science Foundation CAREER awardee, and a fellow of the Alfred P. Sloan Foundation.
