摘要
以自主研发的FunGra绘图环境为背景,提出了以功能图形对象概念为基础的功能图形对象技术·主要包括:基于特征线模型的功能图形对象的类模型,以对象引用及组合运算等方式实现的功能图形对象关系模式,创建功能图形对象的强制转化法及指引线法等·最后,通过软件开发实例说明了该技术的有效性和可行性·
In this paper, the Functional Graphic Object (FGO) technology under the background of self-developed FunGra drawing System is presented. The technology mainly includes the concepts of the FGO class model based on characteristic line model, the relationship mode of FGO realized by object calling and compound computing, the forced-transformation and directive-line method of FGO creation etc. The software development practice shows the validity and feasibility of FGO technology.
