摘要
已知空间R^3中一组离散点{P_i=(x_i,y_i,z_i)}_(i=1)~m和每点P_i处的法向量n_(pi),i=1,2,…,m。假设对点集{P_i}已建立了空间三角形网格△,其中要求以非边界网格点为顶点的三角形的个数为奇数.
In this paper, a method for constructing a smooth interpolation surface that is piecewiseparametric triangular Bezier surface with whole tangent plane continuity (VC^1) and local C^2continuity over a given spatial triangular grid satisfied some conditions is given. The Bezierpoints needed in the Method are reduced. It is possible for us to generate a more complex sur-faces on microcomputers.
