摘　　要：利用奇异混合函数将双三次B样条曲面与虚拟曲面片作混合,构造一类可插值给定数据点的插值曲面,该类曲面在边界处可达到C^2连续,参数α可对曲面片整体形状进行调控。进一步,构造了可局部调控形状的带形状参数的插值曲面。A kind of interpolation surface, which can interpolate the given data points, is constructed in this paper, using the singular blending function to blend the bicubic B-spline surface patches with an imaginary surface patch. The surface possesses C^2 continuity over the boundaries of two patches, and the shape can be totally controlled by changing the parameter a. Furthermore, an interpolation surface with shape parameters which shape can be controlled locally is constructed.
