摘　　要：分析已有的带形状调节参数的扩展Bézier基生成的曲线的方法,提出带调节参数的控制点变换阵的调整曲线形状的方法.其原理是通过将原来的Bézier曲线的控制点变换为新的一组控制点,进而生成新的Bézier曲线.这组控制点的位置与参数相关联,几何意义明显.By analysing the method of generating curves by the extended Bézier based on shape parameters, this paper proposes a new of method of adjusting curve shape by control points matrix with regulating parameters. The principle of which is to convert control points of the curve into a group of new points, thereby generating a new Bézier curve. The position of control points associative with the parameters, which have obvious geometry significance.
