| 摘 要： | 三维人体尺寸信息提取是三维服装CAD系统关键技术,提出了一种计算三角网格曲面上任意2点间近似最短路径的算法.该算法首先定义一个与网格求交的切割平面,连接交点得到网格表面上2点间的初始路径;在此基础上,根据网格的空间几何信息对矫正路径算法做出改进,通过构造截面求交来定义矫正位置,从而避免对曲面进行展平,所得到的近似最短路...

| Abstract: | ize information extraction from 3-D body is a key technology in 3-D garment CAD system.A new algorithm for computing the approximate shortest path between any two vertices on triangular meshes is presented.The algorithm firstly defines a cutting plane which intersects with a mesh.The initial path on the mesh surface is obtained by connecting intersection points.Then it improves the path algorithm according to spatial geometric mesh information.It determines the corrected position by constructing the interse... |
