Research and application of collision problem in flexible fabrics simulation

In the process of flexible fabric simulation, collision detection algorithm is directly related to the simulation efficiency and accuracy. In the paper, we use Fixed Direction Hull (FDH) to solve the problem of collisions, and use the hierarchical region segmentation and human model simplification to reduce the number of collisions. So the real-time simulation of flexible fabric comes true. At the end of the article, we give the results of the simulation experiment.
