Cloth Modeling Simulation Based on Mass Spring Model

Abstract

The crucial problem in cloth simulation based on Physical model is how to solve the motion differential equations. Mass spring model is ideal and it is widely used in cloth simulation. The simulation technology of cloth modeling based on mass spring model is presented completely, fabric mechanics models are established precisely, and several kinds of explicit numerical integration are compared in detail, especially, using RK-4 method can greatly improve system’s stability. This cloth simulation method is applied to cloth software. Examples have proved that this method is advanced and practical.

Accurate simulation of draped fabric sheets with nonlinear modeling

“…Due to the features of fabrics, that is, high softness, high flexibility, anisotropy, nonlinearity in mechanical properties, and mass discreteness, accurate shape modeling of draped cloths faces a number of challenges, and prediction accuracy and simulation efficiency are two major issues. This paper proposes a shape simulation method based on the concept of a particle spring model (PSM), 1,2 but using nonlinear springs to describe the mechanical properties and behavior of a fabric.…”

“…17 proposed a mechanics-based elastic deformation model, while Semler 18 used the mixed finite element method (FEM) to calculated the fabric draping behavior by considering the sheet to be an isotropic shell. The particle system model 19–21 and PSM 1,2,22–26 are representatives of the discrete physical models.…”
