截面数据重构三角网格面算法的研究

Research on Triangulation Reconstruction from Section Data

截面数据是逆向工程中常见的曲面重构数据来源。采用相邻轮廓线间添加剖分线段的方法实现三角网格面的生成,并且在传统算法基础上,加入了“缓剖分”和“错位修正”等策略,使所述算法在输出结果的准确性方面得到了大幅提升。

Section data.is a common data source in reverse engineering. The author makes the mesh generalization by dissecting between each pair of neighboring contour lines. With ＂cached dissection＂ and ＂cross fixing＂ techniques based on traditional algorithms, the presented algorithms in this paper improves the result greatly on the aspect of accuracy.
