Efficient cloth simulation based on the material point method

Abstract

In this article, we propose a novel cloth simulation method based on the material point method (abbr. MPM). The response to the cloth strain is characterized by three separated models: the continuous in-plane hyperelasticity, the discrete bending elastoplasticity, and the continuous frictional contact elastoplasticity.We make use of the moving least squares MPM (abbr. MLS-MPM) transfer scheme and a discrete bending model to reduce computation overhead. We further extend the hyperelastic bending model to be elastoplastic, which can be further used for the simulation of a wide range of thin shell materials, such as thin metal sheets. A fast and approximate signed distance field generation method for humanoid animation is also proposed. Experimental results demonstrate that our method can efficiently and robustly simulate high-resolution challenging scenes with hundreds of thousands of triangles.
