- Title: Surfaces: Modelling and Analysis
- Date & room: to be defined
Trimmed tensor-product B-spline surfaces are ubiquitous in design but impose a heavy tax on downstream engineering analysis. Starting with classical subdivision, this community has developed a rich set of alternative surface representations that can model isotropic and anisotropic multi-sided surface pieces without trimming.
This talk will argue that several constructions can now deliver what designers characterize as class A surface quality and are directly suitable for isoparametric analysis. As an example, polyhedral splines and evolving guide subdivision are now available as open source code. But do these new tools really address the reasons why designers apply trimming-based operations?
Jorg Peters is Professor of Computer and Information Sciences at University of Florida. He is interested in representing, analyzing and computing with geometry. To this end he has developed new tools for free-form modeling and design in spline, Bezier, subdivision and implicit representations. He is heading the TIPS project to enable surgeon-educators to author VR-based simulations with force feedback. Jorg obtained his Ph.D. in 1990 in Computer Sciences from the University of Wisconsin, Carl de Boor advisor. In 1991 and 1992, Peters held positions at the IBM T. J. Watson Research Center and Rensselaer Polytechnic Institute before moving to the computer science department of Purdue University. In 1994, Peters received a National Young Investigator Award. He was tenured at Purdue University in 1997 and moved to the University of Florida in 1998 where he became full professor. In 2014, Peters received the John Gregory Award, the highest award in the area of Geometric Design.
