摘要
分析了曲线曲面形状和位置特征要素 ,对曲线与曲面的相似特征进行了定义 ,对平面、曲面和曲线的相似特征给出了统一的表达式 .提出了相似率的概念 ,用以描述局部和全局的相似特征 。
This paper analyses feature elements of shape and position of the curves and sur efaces,defines similarity feature of theirs,gives them a universal formula.The d efinition of similarity rate is given so as to desvribe local and globle similar ity features.Also a method is indroduced for forming complex curves and surfaces with different similarity feature.It is applied extensively in geometric modeli ng
