【Abstract】 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.更多还原
