中文摘要：

文章分析已有的带形状调整参数的以Bernstein基构造的Bézier曲线的方法,提出带调整参数的控制点变换矩阵的方法调整曲线的形状.其原理是通过将原来的Bézier曲线的控制点变换为一组新的控制点,进而生成新的Bézier曲线.这组控制点的位置与参数相关联,并且结构简单,几何意义明显.

英文摘要：

In this paper,the existing belt shape parameters to Bernstein and the base structure of the Bezier curve method are analyzed. Adjusting parameters of the control points of transformation matrix method to adjust the shape of the curve are given out. The principle is that a new the Bezier curve generate with the original control points of the Bezier curve transformation for a new set of control points. The position of this set of the control points is related with associated parameters. Moreover,the structure is simple. And the geometrical meaning is obvious.
