Abstract: In the field of cloth modeling, how to quickly simulate the fold details after deformation is a hot topic of research. By using the method of multi-level fabric modeling, the accuracy and speed of modeling can be effectively balanced with different precision in different deformation areas. The existing work is mainly to dynamically calculate the curvature of the particle areas in the process of deformation and divide the multi-level areas according to the artificially set threshold. However, in most scenes, the deformation mode of the cloth is irregular, and the fixed threshold may affect the simulation effect of the cloth. By using the particle swarm algorithm to search the fabric surface, the searching efficiency of the curving part is improved, the modeling speed and precision are also optimized. Consider the mathematical model of air resistance, the numerical integration method of particle dynamics is used to optimize the calculation method of fabric simulation. Results show that compared with the existing cloth simulation method, this method can quickly detect the fabric curving area and determine whether need to be refined, and can show the air resistance on cloth simulation process.
