Cloth simulation is an important part of computer animation and has significant application value in clothing design and manufacturing. Generally speaking, position-based dynamics methods are less accurate than force-based methods, but they provide visual plausibility and have fast, stable, and controllable characteristics, making them particularly suitable for use in interactive environments. Position-based dynamics cloth simulation methods have become popular in the clothing industry. This article provides an overview of the cloth mesh model, cloth constraint conditions, cloth posi-tion-based dynamics simulation algorithms, and their research status and important achievements by reviewing relevant literature. It summarizes the main applications of position-based dynam-ics-based cloth simulation in the clothing industry and summarizes the development trends and challenges of this technology.
