摘要
构造了带形状参数的2m+1次Ball基及Ball曲线。它具有和Ball基及曲线同样的性质。通过3次带参数的Ball曲线生成圆形和花瓶的实例说明在不变动控制点的情况下,通过调整形状参数λ值可根据需要达到控制曲线形状的目的。
In this paper, 2m ＋ 1 order Ball bases and Ball curves with shape parameters are constructed using recursive equations. They have the same properties as Said - ball bases and curves. Finally, The circle and the vase are generated by 3 order Ball curves with different parameters, and the experiments show the Ball curve shapes can be controlled by adjusting the shape parameters and not need to move the control points.
