摘要
通过对关系型数据结构的分析,提出图形参数化的概念,并且给出一种基于关系型数据结构的图形参数化方法.该方法从图形数据及结构入手,通过记录图形参数及图形设计过程生成参数化图形,在实际应用中,方便通用,行之有效.
By analyzing relational data structure, the paper presents the conepts of design parametrization and a new graphic parametrization method for on relational data structure is given. The method starts with graphics' data and structure, by recording the parameters of drawing and the process of parameterized drawing, graphics is available quickly.
