Fast and Accurate Intersections on a Sphere
Hongyu Chen, Paul A. Ullrich, Julian Panetta
We introduce a fast, high-precision algorithm for calculating intersections between great circle arcs and lines of constant latitude on the unit sphere. We first propose a simplifi…

A Neural-preconditioned Poisson Solver for Mixed Dirichlet and Neumann Boundary Conditions
Kai Weixian Lan, Elias Gueidon, Ayano Kaneda +2
We introduce a neural-preconditioned iterative solver for Poisson equations with mixed boundary conditions. Typical Poisson discretizations yield large, ill-conditioned linear syst…

Analytic Eigensystems for Isotropic Membrane Energies
Julian Panetta
We extend the approach of [Smith et al. 2019] to derive analytical expressions for the eigenvalues and eigenmatrices of an isotropic membrane energy density function $ψ: \mathbb{R}…
