Multi‐Resolution Cloth Simulation

Abstract

We propose a novel, multi-resolution method to efficiently perform large-scale cloth simulation. Our cloth simulation method is based on a triangle-based energy model constructed from a cloth mesh. We identify that solutions of the linear system of cloth simulation are smooth in certain regions of the cloth mesh and solve the linear system on those regions in a reduced solution space. Then we reconstruct the original solutions by performing a simple interpolation from solutions computed in the reduced space. In order to identify regions where solutions are smooth, we propose simplification metrics that consider stretching, shear, and bending forces, as well as geometric collisions. Our multi-resolution method can be applied to many existing cloth simulation methods, since our method works on a general linear system. In order to demonstrate benefits of our method, we apply our method into four large-scale cloth benchmarks that consist of tens or hundreds of thousands of triangles. Because of the reduced computations, we achieve a performance improvement by a factor of up to one order of magnitude, with a little loss of simulation quality.

Hierarchical Cloth Simulation using Deep Neural Networks

“…Because high-resolution simulation has been employed for computer graphics contents, hierarchical methods have been proposed for efficient simulation. For fast cloth simulation, the unchanging hierarchical cloth [28] and dynamically changing multi-resolution cloth models [12] have been proposed. The multi-resolution shape matching method [3] has been proposed to extend the hierarchical position-based method [16] to cloth simulation.…”

Cloth Simulation with Triangular Mesh Adaptivity

“…Differently from the other approaches, Lee et al [23] used a super refined mesh and tried to reduce the computational cost by a numerical simplification of the system of equations. Grinspun, Krysl and Schröder [24] refined the shape functions from the finite element method instead of modifying the mesh elements.…”

A GPU‐based Streaming Algorithm for High‐Resolution Cloth Simulation

“…Techniques to perform high‐resolution cloth simulation have been proposed by Selle et al [SSIF09] and used multi‐core CPUs. Recently, adaptive meshes have been used [LYO*10, NSO12] for multi‐resolution cloth simulation.…”
