摘要: 利用构造性代数几何的理论与方法, 使用两个球面和一个单叶双曲面构造出一种结构, 使之可以用来光滑拼接任意两个轴线相交的二次曲面, 并以两个轴线相交的圆柱面为例说明了该结构的有效性. 使用该方法计算量小, 所得混合曲面次数低.

关键词: 光滑拼接, 几何连续, 二次曲面

Abstract: The theory and the method of constructive algebraic geometry were used to construct a kind of structure from two spheres and a hyperboloid of one sheet which can be used to blend any two kinds of quadric surfaces smoothly. This method is easy to be realized and the degrees of the blending surfaces are the lowest. Finally we also gave an example to show the effectivity of this structure by blending two cylinders.

Key words: blending, geometric continuity, quadric surface
