With the development of the simulation technique, deformable cloth simulation has become highly desired. It can be widely used in many fields such as game, animation, virtual surgery, etc. Real-time algorithm is the most urgent bottleneck problem that needs to be solved. This paper introduces a solution to implement deformable simulation of cloth in real time, accomplished through using a meshless simulation technique, which is known as position-based dynamics, implemented using CUDA parallel framework. The simulation results are directly sent to vertex buffer object for rendering to avoid the costly communication between CPU and GPU. The experimental results show significate improvements on performance in comparison to CPU algorithm.
