摘　　要：当三维服装试穿在不同的人体模型上时,服装与人体模型间发生穿透现象并非罕见,因此为提高三维扫描服装模型的重用性,提出一种基于同层穿透补偿的算法。这种算法将服装与人体模型间的穿透检测和补偿分别划分为服装三角形顶点与人体三角形之间、服装三角形边与人体三角形之间的求交与补偿。针对过大的穿透,要通过服装和人体模型姿态同步解决。实验结果证明,该算法在体现三维扫描服装重用性方面十分有效。It is not rare for penetration phenomena to occur between garment and mannequin when 3-D garment is dressed onto various mannequins.In order to enhance the reusability of the 3-D scanned garment model,an algorithm based on same layer penetration compensation has been proposed,in which,the penetration detection and compensation between garment and mannequin are expressed respectively by the crossover and compensation between garment vertex and body triangle,and between garment edge /body triangle.The over-deformation is compensated via the position adjustment procedure.Experimental results verify that this method is an efficient approach for reusing 3-D scanned garment models.
