Particle Sorting Algorithm Based on Stretching Tensor

摘要

In this paper, we come up with particle sorting algorithm which is based on stretching tensor to address this critical phenomenon that we call it "super elastic deformation". Firstly, we should build a cloth mesh geometry model by mass-spring model, secondly, we compute the stretching tensor value of the particle in the simulation process, and then sort the values descending, lastly, we picked the particles of larger value of the tensile tensor, then fix the particle position by using Provot method. The result shows the one we proposed can effectively avoid cloth shock issue compared with the existing algorithms, and improve the computation efficiency without affecting the simulation result.
