本文介绍了一种由截面轮廓重建曲面的有效方法。相邻截面之间的表面基于二维约束Delaunay三角剖分的一致利用进行重建。三角剖分用于提取参数域，并在一般框架中解决与对应、平铺和分支相关的问题。执行自然距离插值以完成添加的中间点的映射。通过曲面光顺和网格重划分优化初始曲面三角剖分。几个例子来证明所提出的方法的有效性和效率。版权所有© 2005年约翰威利父子有限公司。
This paper introduces an efficient method for surface reconstruction from sectional contours. The surface between neighbouring sections is reconstructed based on the consistent utilization of the two‐dimensional constrained Delaunay triangulation. The triangulation is used to extract the parametric domain and to solve the problems associated with correspondence, tiling and branching in a general framework. Natural distance interpolations are performed in order to complete the mapping of the added intermediate points. Surface smoothing and remeshing are conducted to optimize the initial surface triangulations. Several examples are presented to demonstrate the effectiveness and efficiency of the proposed approach.
