摘要
提出了三维等值线生成的新算法．通过对曲面的扩展及离散，生成三维曲面的三角形网格．在网格节点构成的空间点集中，进行有序地搜索，并运用线性插值法获取三维曲面上系列的等值点，从而实现三维等值线的生成。
A new algorithm for the generation of the three dimensional contour line is developed. The triangular meshes of three eimensional curved surfaces are generated by development and discretization of the surfaces. Ordered search is carried out on the space point set by the nodes of the meshes, and a series of points on the 3D surfaces are obtained by linear interpolation. Three dimensional contour lines are generated by connecting these special points.
