| 摘 要： | 本文从理论上分析了三次 B 样条曲线的控制多边形顶点相对位置对曲线段中的拐点、尖点及二重点的分布的影响,提出两个控制曲线段形状的比值,给出了曲线段中出现上述特殊点时它们的取值范围;为调整曲线段形状提供了理论基础.

| Abstract: | The paper analyses the effect of the relative vertex positions of the control polygon to the diatribution of the points of inflection,double point,and cusp in the B-spline segment.Two ration are discoved that express this effect.The values are calculated in any case. |
