报告题目:Moebius Geometry Processing


The mainstream approaches in digital geometry processing employ triangular (simplicial) meshes, discretize differential quantities using finite-element function spaces, and define transformations with piecewise-affine maps. I will describe how discrete Moebius geometry provides a novel alternative to these paradigms, by using circles as its basic elements, and describing quantities like conformality and regularity through the invariants of Moebius geometry. This paradigm allows to develop various capabilities, such as polygonal (non-triangular) mesh conformal deformations and multi-resolution design of unconventional mesh patterns with spherical precision. The applications for discrete Moebius geometry processing are within graphics, architectural geometry, and shape design.


Amir Vaxman is an assistant professor in the Geometric Computing Group in the Department of Information and Computing Sciences at Utrecht University, The Netherlands. Before his position at UU, he was a postdoctoral fellow in TU Wien (Vienna) at the Geometric Modeling and Industrial Geometry group, where he also received the Lise-Meitner fellowship. He earned his BSc in computer engineering, and his PhD in Computer science, both from the Technion-Israel Institute of Technology. His research interests are geometry processing and discrete differential geometry, focusing on directional-field design, unconventional meshes, constrained shape spaces, architectural geometry, climate and medical applications.
