Abstract: A system for multilevel simulation of an animation cloth is provided. The system includes a multilevel area generation module, a curvature calculation module, a curvature comparison module, and a dynamic simulation module. The multilevel area generation module divides a plurality of grid units of the animation cloth into a plurality of level sub-areas based on a multilevel technique, wherein each of the level sub-areas is generated by dividing an upper level sub-area. The curvature calculation module calculates the curvatures of the level sub-areas according to the plane vectors of the grid units in a frame. The curvature comparison module compares the curvatures of the level sub-areas with a flatness threshold. The dynamic simulation module calculates the plane vector of each grid unit in a next frame through different method according to the comparison result of the curvature comparison module.
