Look Both Ways Before You Cross: Lifting Cross Fields From 2D Visual Priors
Dale Decatur, Jacob Serfaty, Oded Stein +2
We present CrossLift, a technique for computing cross fields on meshes guided by visual features in images. We leverage powerful text-to-image priors that are capable of synthesizi…
Convex Quadratic Distance Field Computation
Yue Ruan, Albert Chern, Tzu-Mao Li +2
Methods for computing distances from sources on discrete meshes commonly either compute geodesics directly on polyhedral surfaces or approximate the distance in a finite-element fr…
Power-Linear Polar Directional Fields
Jiabao Brad Wang, Amir Vaxman
We introduce a novel method for directional-field design on meshes, enabling users to specify singularities at any location on a mesh. Our method uses a piecewise power-linear repr…
Learned Adaptive Mesh Generation
Zhiyuan Zhang, Amir Vaxman, Stefanos-Aldo Papanicolopulos +1
Elliptic Partial Differential Equations (PDEs) play a central role in computing the equilibrium conditions of physical problems (heat, gravitation, electrostatics, etc.). Efficient…
