摘要
提出一种由断层测量数据直接生成 STL 文件的方法 ,其中两端层面的三角剖分符合 Delaunay优化准则 ,而任意两相邻中间层轮廓之间的三角面片连接采用“最小局部极角 "的原则。并给出了算法和算例。
A new method for generating STL models directly from cross-sectional measured data is proposed. The triangulation of planar contours of the first and the last layers meet Delaunay optimality criteria and the principle of the least local polar angle is used to connect the triangular facets between a couple of arbitrary adjacent contours in middle layer. Finally, an application example is given to illustrate the feasibility of the method.
