Description: 生成、显示B样条曲线： （1）用鼠标或者光标输入控制点，在屏幕上用图形符号标记显示。 （2）自定义输入曲线次数。 （3）可选择4种曲线类型。 (4)可以对顶点位置，曲线次数，曲线类型进行修改。-generation, showed that B-spline curves : (1) to use the mouse or the cursor input control points on the screen with graphic symbols marking show. (2) Since the definition of input frequency curve. (3) the option of four types of curves. (4) can be right vertex position, the number of curves, curve types of changes. -Generation, showed that B-spline curve: (1) with the mouse or cursor input control points, on the screen with graphic symbol markings.
