摘要
讨论了具有几何连续性的Ｂｅｔａ样条曲线的性质，并以此构成受双参数控制的双Ｂｅｔａ样条曲面．给出这种曲面的算法和特性．并通过实例说明，曲面的形状如何受参数β１和β２从变化的影响．
This paper discusses properties of beta spline with geometric continuity,which forms a bibeta spline surface controlled by double parameters. The authors give algorithm and characteristic of this surface, and through examples explain how the shape of the surface is influenced by the change of parameters β1 and β2.
