【摘要】 虚拟服装设计在服装制造业中一直有着很重要的地位。近年来计算机服装辅助设计的应用场景越来越多,研究实现一个合理高效的衣片虚拟缝合算法具有良好的工程应用价值。本文基于课题组自主开发的“个性化虚拟服装设计系统平台”上实现了衣片交互设计功能,研究实现了衣片缝合与折叠算法。对衣片进行三角网格剖分,采用生成的三角面片模拟衣物,借助有限元分析模拟衣服物理运动,使用距离场技术模拟三维人体模型与衣片的碰撞效果。针对衣片缝合中的一对一、一对多、多对多等缝合对应关系,提出了基于近似匹配的分治算法,有效地解决了自由缝合的问题。针对缝合中需要面片折叠的情况,借鉴Bridson折叠效应模型,提出了缝合线折叠算法,对缝合线附近面片施加额外弯曲力约束实现了三维虚拟服装的真实感折叠效应,在测试环境下表现良好。更多还原

【Abstract】 Virtual clothing design has always been a very important position in the garment manufacturing industry.In recent years,there are more and more application scenarios of computer aided design,and it has a good engineering application value to research a reasonable and efficient clothing virtual stitching algorithm.Based on the self-developed "personalized virtual clothing design system platform",CAD garment design features have been developed,the algorithm of garment sewing and folding has been achieved.The garment pieces are split into triangular meshes,the finite element analysis has been used to simulate the physical movement of clothes,and distance field technology has also been used to simulate the impact of three-dimensional human body model and clothing pieces.According to the one-to-one,one-to-many,many-to-many sewing situations,a divide-and-conquer algorithm based on the approximate matching had been proposed to solve the problem of free stitching effectively.A suture folding algorithm is proposed based on the Bridson Fold Effect Model.The actual folding effect of the three-dimensional virtual clothing has achieved by applying additional bending force to the patch near the suture.The algorithm performs well in the test environment.更多还原
