APPLIED MATH SEMINAR Title: Towards Real-Time Massive Geometry Processing Speaker: Gabriel Taubin, Brown University When/where: Tuesday, April 5th, 4:15PM, AKW 400 Abstract: In Geometry Processing, a field which has developed during the last ten years, concepts from applied mathematics, computer science, and engineering are used to design efficient algorithms for the acquisition, manipulation, animation and transmission of complex 3D models. A number of methods have been proposed to smooth, denoise, edit, compress, transmit, reparameterize, and animate very large polygon meshes, based on topological and combinatorial methods, signal processing techniques, constrained energy minimization, and the solution of diffusion differential equations. IN particular, polygon models, which are used in most graphics applications, require considerable amounts of storage, even when they only approximate precise shapes with limited accuracy, and must be compressed by several orders of magnitude for fast network access. In this talk I will present and overview of the field, pointing out some of my contributions, and will describe some ongoing research projects.
