Abstract：A novel method based on multilevel meshes is proposed to simulate
the cloth draping process rapidly on a complex model. Considering of
the difficulty of computing the realtime collision between cloth and
complex models by normally methods, the draping process of cloth is
divided into several phases and at each phase the mesh size is
smaller than its previous one. The optimized 1-to-4 split is used to
drive the rapid changes in the grid hierarchy and to simplify the
calculations. We choose the widely used ellipsoid as the bounding
cell to enclose the complex models in the environment. The ellipsoid
avoids the complex structure of hierarchical bounding box and
eliminates the impossible collision model area rapidly. Experiments
demonstrate that this method can accelerate the draping process of
cloth and decrease the number of iterations and the calculation of
collision detection. Further mesh refinement improves the reality of
cloth when it reaches the final position and ensures the realism of
the simulation in real time.
