Data-Driven Cloth Simulation

We present a virtual fitting animation system that uses BVH motion data to drive3D human models with cloth simulation. Our approach adopts the skeleton of the BVH file to the3D human character and attaches the skeleton to the surface, allowing for animating the character using skeletal motion data. An automatic method for animating characters is presented by using the analogy to the heat equilibrium to find the weights between the vertices of the surface and the bones of the skeleton. To generate better results, the Spherical Blend Skinning (SBS) is employed to avoid collapse and candy wrapper artifacts at a low computational cost and memory space. We use the physics engine PhysX of NVIDIA to animate clothes. We construct bounding boxes for the characters to handle collision detection and collision response with clothes, generating folds, flutters and other clothes simulation effects.Experimental results show that our approach can produce satisfactory results and has practical application values. The developed system is easy to use even for novices.
