Claim One:
1. A system for multilevel simulation of an animation cloth, comprising a multilevel area generation module, dividing 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; a curvature calculation module, coupled to the multilevel area generation module, the curvature calculation module calculating a curvature of each of the level sub-areas in a first frame according to a plurality of first plane vectors of the grid units; a curvature comparison module, coupled to the curvature calculation module, the curvature comparison module comparing the curvatures of the level sub-areas with a flatness threshold; and a dynamic simulation module, coupled to the curvature comparison module, the dynamic simulation module calculating a second plane vector of each of the grid units in a second frame through different methods according to the comparison result of the curvature comparison module.
