Cloth Animation Based on Particle Model with Constraint

摘要

hysically-based methods are often used to simulate cloth animation. For generating realistic cloth animation, stability and effectiveness are two most important aspects which need to be considered. In cloth animation, the users often need to attach a vertex to make sure the vertex is free collision or reduce the excessive elongation of some edges. Some existing methods directly adjust the particle position or use stiff spring model for the simulation regarding these facts. However, these methods can cause energy loss or system performance degradation. In this paper, we propose a novel method to simulate cloth based on physically-model with constraints. Cloth deformation is solved using a physically-based model, and then constraints are iteratively imposed to avoid over-elongation and penetration. The experiments show that our method is stable and effective, and can generate realistic cloth animations.
