Distinguished Guest Lecturer

GENERATION AND COMPRESSION OF 3D MODELS AND ANIMATIONS

Jarek Rossignac
College of Computing, GVU Center, IRIS Cluster
Georgia Institute of Technology

Thurs., Oct. 21st
3:30pm, 480 Dreese Labs
All interested parties are invited.
Refreshments will be served immediately preceding the talk.

Abstract:The first part of the lecture presents new direct manipulation techniques (Twister, Bender) for the design of 3D shapes and animations, They were developed under the NSF Digital Clay project and permit to grab, warp, bend, and twist a 3D shape by moving both hands through space. The second part focuses on the representation (Corner Table) and compression (Edgebreaker, Delphi) of such 3D shapes and of their animations (Dynapack). The third part discusses retiling approaches (PRM, SwingWrapper), which enhance compression, and post-processing approaches (EdgeSharpener, Sharpen&Bend), which automatically restores smooth surfaces and their sharp intersections from the feature-insensitive retiling.

Bio: Jarek Rossignac is a Full Professor in the College of Computing and the Chair of the IRIS (Interaction with Robots, Images, and Shapes) cluster at the Georgia Institute of Technology in Atlanta, Georgia, USA. He is also an active member and former Director of the GVU (Graphic, Visualization, and Usability) Center. His current research is focused on the interactive design, compression, progressive transmission, and visual inspection of multi-resolution representations of complex 3D and 4D models. He is also the PI of the NSF-CARGO project on the "Multi-scale Topological Analysis of Deforming Shapes" and a co-PI on the large NSF-ITR "Digital Clay" project focused on developing a computer-controlled surface that can be used to make real three-dimensional objects whose shape may be altered both by human hands and by software applications. In 1985, he received a PhD in E.E. from the University of Rochester, NY, for his work in Solid Modeling. Until 1996, he was Senior Manager and Visualization Strategist at IBM's T.J. Watson Research Center, where he oversaw research activities in 3D graphics, CAD, and VR and where he managed the development of two IBM Visualization products. He has authored 18 patents and over 100 papers, for which he received 5 Corporate Awards, 8 Best Paper Awards, and the Senior Faculty Research Award from the College of Computing. He chaired 20 conferences, program committees, or award juries and served on the Editorial Boards of 7 professional journals and on over 50 Technical Program committees. He was elected Fellow of the Eurographics Association in 2002 and is the Chair of the Solid Modelling Association and of the 2005 ACM Symposium on Solid and Physical Modeling.
