摘要
讨论了有理Ｂｅｔａ样条曲面的性质，给出了其权因子的几何解释，提出有理Ｂｅｔａ样条曲面的算法及其在计算机上实现的步骤。
This paper discusses properties of rational Beta spline surfaces and gives the geometric interpretation of weighing factors. Also, it presents the algorithms and implementation. Finally an example is analyzed to explain how the shape of the surface is influenced by weighing factors.
