Design And Implementation Of Human Dressing Algorithm

Dressing is one of common daily activities. With the improvement of the performance of computer and the theory of computer graphics, cloth simulation and human animation have been developed rapidly, which makes it possible to design and implement virtual realistic dressing algorithm. The purpose of this thesis is designing realistic 3D dressing actions and generating the animation according to common dressing style in life.On the basis of the previous research on the computer animation field at home and abroad,the dressing was decomposed into a set of basic primitive actions. These primitive actions couldn't be decomposed any more,but could be combined to different dressing styles. Basic primitive actions included gripping, release and alignment. These primitive actions were applied to mainstream of dressing. There were two common dressing styles: sleeveless cloth and long sleeved cloth. Adaptive mesh refinement algorithm was designed for sleeveless cloth, which was applied in garment simulation. Anisotropic adaptive mesh in the calculation was featured in both physical properties and calculation of the cost. The physical solution was changed larger in a intensive-mesh region, and was changed smaller in the physical solution in a sparse-mesh region. Also, the thesis was introduced traversal action, which was a special primitive action for long sleeved cloth. The requirement from traversal action to collision detection and handling between human body and cloth particles was strict.Furthermore, the thesis was introduced non penetrating filtering method and was introduced impact zone to handle collision respectively to improve accuracy and performance.
