Fast Simulation of Cloth-Rigid Body Based on PBD

Because the excellent performance of the position-based dynamics (PBD) method, the PBD gains popularity among cloth simulation and computer animation. Based on unified adaptive PBD, we apply collision constraints to cloth and rigid body models to speed up the process of collision detection between cloth and complex models, we conduct a bounding box high-level collision culling detection algorithm. Moreover,friction is calculated by the speed of the cloth to make the cloth simulation more realistic. Compared with continuous collision detection (CCD), our method improves the simulation speed several times.The experimental results demonstrate that we has the wide range of applicability and the the simulation effect is stable.
