FreeForm: Reduced-Order Deformable Simulation from Particle-Based Skinning Eigenmodes
Donglai Xiang, Vismay Modi, Rishit Dagli +5
We present a novel formulation for mesh-free, reduced-order simulation of deformable hyperelastic objects. Existing work in reduced-order elastodynamic simulation represents the in…
Coordinate Condensation: Subspace-Accelerated Coordinate Descent for Physics-Based Simulation
Ty Trusty
We introduce Coordinate Condensation, a variant of coordinate descent that accelerates physics-based simulation by augmenting local coordinate updates with a Schur-complement-based…
Sparse, Geometry- and Material-Aware Bases for Multilevel Elastodynamic Simulation
Ty Trusty, David I. W. Levin, Danny M. Kaufman
We present a multi-level elastodynamics timestep solver for accelerating incremental potential contact (IPC) simulations. Our method retains the robustness of gold standard IPC in…
FastAtlas: Real-Time Compact Atlases for Texture Space Shading
Nicholas Vining, Alexander Majercik, Floria Gu +5
Texture-space shading (TSS) methods decouple shading and rasterization, allowing shading to be performed at a different framerate and spatial resolution than rasterization. TSS has…
Subspace Mixed-FEM for Real-Time Heterogeneous Elastodynamics
Ty Trusty, Otman Benchekroun, Eitan Grinspun +2
We propose a reduced space mixed finite element method (MFEM) built on a Skinning Eigenmode subspace and material-aware cubature scheme. Our solver is well-suited for simulating sc…
Mixed Variational Finite Elements for Implicit, General-Purpose Simulation of Deformables
Ty Trusty, Danny M. Kaufman, David I W Levin
We propose and explore a new, general-purpose method for the implicit time integration of elastica. Key to our approach is the use of a mixed variational principle. In turn its fin…
