Untangling Surfaces via Shape and Mesh Repulsion

Jiří Minarčík*, Michael Liu* (equal contribution), Keenan Crane, Minchen Li Self-intersections are widespread in surface meshes and invalidate downstream simulation, fabrication, and learning pipelines. Existing approaches typically treat self-intersections as local collision events, but embeddedness (i.e., lack of self-intersections) is … Continue reading

Low-Rank Koopman Deformables with Log-Linear Time Integration

Yue Chang, Peter Yichen Chen, Eitan Grinspun, Maurizio M. Chiaramonte We present a low-rank Koopman operator formulation for accelerating deformable subspace simulation. Using a Dynamic Mode Decomposition (DMD) parameterization of the Koopman operator, our method learns the temporal evolution of … Continue reading

Tube Maps: Fast SPH Boundary Handling in Tubular Coordinates

Daria Nogina, Silvia Sellán Smoothed Particle Hydrodynamics (SPH) simulations rely on accurately and efficiently modeling fluid-solid interactions. However, particle-based coupling strategies introduce non-deterministic discretization errors, and implicit methods achieve high accuracy at the cost of expensive numerical integration. We introduce … Continue reading
