局部网格狭长三角形的品质改善及实现

Improvement and Realization of Quality of Local-long-narrow Triangular Mesh

通过对传统三角剖分的讨论 ,提出了局部网格狭长三角形品质改善的方法 ,此方法通过对狭长三角形的删除和对新产生的顶点作算法的调整 ,有效地改善了狭长三角形 ,使三角网格具有良好的形态 .

Through a discussion on the traditional triangulation,an improved method of local-long-narrow triangular mesh is presented in the text.By deleting the long narrow triangular and adjusting the new top-point,this method can improve long-narrow shaped triangles effectively,and the triangular mesh will have its good shape.
