Dynamic garment simulation based on multi-resolution ellipsoid bounding box

The collision detection and response between the garment and human body models are an important factor affecting simulating speed when dealing with dynamic garment simulation.In order to improve the efficiency and effect of the simulation,this paper presents a new method based on the ellipsoid bounding box in multi-resolution.After subdividing the human model by using octree,we first reorganize and optimize the voxel.Then we merge the sphere bounding boxes based on the multi-resolution ellipsoids for accelerating the collision detection,and form a series of model approximations.The experimental result shows that the simulation is more realistic and it is helpful to improve the efficiency of the garment simulation.
