Recent advances in self-collision detection, cloth modeling, and 3D-printed characters

Friday, November 30, 10AM – 11AM
POB 2.402 (Electronic)

Doug L. James

This three-in-one talk will summarize three of our recent projects presented at SIGGRAPH 2012. First, I will discuss a fundamentally new way to accelerate self-collision detection for deforming triangle meshes by exploiting knowledge about the minimum deformation energy required to introduce self collisions. Second, I will describe "Stitch Meshes," a new way to model the intricate inter-looping structures of yarn-level cloth garments using familiar polygon meshes. Third, I will talk about our approach for 3D printing of articulated characters based on automated geometric processing of skinned character models commonly used in computer graphics.

BIO: Doug L. James is Associate Professor of Computer Science at Cornell University. He holds three degrees in applied mathematics, including a Ph.D. in 2001 from the University of British Columbia. 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 recipient of the National Science Foundation CAREER award, a fellow of the Alfred P. Sloan Foundation, and spent his 2011-12 sabbatical working on "sound rendering" under a Guggenheim fellowship.
