| 摘 要： | 构造出一种用于参数曲线自由变形的分段多项式函数，称之为缩放因子，将该因子作用于待变形曲线，从而使曲线发生形变。通过交互改变控制参数，可这到预期的变形效果。实验表明，这种方法数学背景简单，易于控制，操作方便，重复使用可获得丰富的变形效果，适用于几何造型、计算机动画等领域。

| Abstract: | A fragmental polynomial function for free-form deformation of parametric curve is constructed;it is called as extension factor.Using this factor to deform the parametric curve needed deformation,through changing the controlled parameter,the ideal deformation effect can be got.The experiment result shows that the mathematic background of this method is simple,it is easy to control and manipulate,and we can get plentiful deformation effect by using it repeatedly.This method can be used in many fields such as ... |
