摘要
把曲面分为可展曲面和不可展曲面,对可展曲面用曲面展开算法展成平面,对不可展曲面用曲面分割算法转化成平面片,在平面上运用Delaunay三角划分法进行网格划分,然后把网格节点反映射到曲面上,从而实现任意曲面的三角形网格划分。
This paper classifies surfaces into developable surface and undevelopable surface.The former can be converted into plane with surface developing algorithm,while the latter can be divided into planes with surface dividing algorithm.The Delaunay triangular meshes are generated on the plane,where the mesh nodes can be reflected to the surface reversely,which accomplishes the goal of triangulation of surface.
