各向异性适应非结构化三角形表面网格生成使用一个新的和有效的程序的基础上Delaunay原则。网格各向异性由表面上的度量变化控制。为了改善曲面网格的定义，一个推广的Farin的算法已经发展到获得\lq $G^1$\rq曲面连接三角Bezier曲面片。提出了不同的局部网格算子来控制曲面网格的生成过程，并给出了一种各向异性网格的生成算法。该算法是在考虑其3D泛化的情况下开发的。
Anisotropic adapted unstructured triangular surface grids are generated using a new and efficient procedure based upon the Delaunay principle. The mesh anisotropy is controlled by a change of metrics over the surface. In order to improve the surface grid definition, a generalization of the Farin's algorithm has been developed to obtain \lq $G^1$\rq surfaces by joining triangular Bezier surface patches. Different local mesh operators are proposed to control the surface grid generation process and a remeshing anisotropic grid generation algorithm is described. This algorithm has been developed keeping in mind its 3D generalization.
