Title: Chebyshev Nets from Commuting PolyVector Fields
Presented By: Mirela Ben Chen, Technion

Abstract:
In this talk I will describe a new method for computing global discrete Chebyshev nets (i.e., quad meshes with equal edge lengths) on triangular meshes. We formulate the problem using global parameterization with commuting (Poly)Vector Fields (as opposed to the commonly used curl-free fields), and design and solve efficiently the corresponding optimization problem. We compute, for the first time, Chebyshev nets with automatically-placed singularities, and demonstrate the realizability of our approach using real material. Joint work with Andrew O. Sageman-Furnas, Albert Chern and Amir Vaxman.
