摘要
图元信息管理在图形编辑与CAD应用研究中均具有重要的作用。本文在分析了图元信息的特点的基础上,提出了图元信息的有效管理方法,包括为减缓内存紧张而提出的内、外存控制方法,为减少内、外存交换次数而引入的缓冲技术,光标定位快速搜索方法以及交互修改保持数据一致性的方法。应用本文中所提出的方法,可研制出有效的图元信息管理软件系统。
The efficient management for the graphic element information plays an important role in the graphic edit and the applied research of CAD. On the basis of analysing the features of the graph- ic element information, this paper presents the efficient management methods of graphic element infor- mation, which consist of the follow methods: control method of the interior and the exterior memory, prensented for purposes of alleviating the tension of memory; buffer technique, introduced for purposes of deducing the times to exchange the interior and exetrior memorg; fast search metkod allocated by light-mark as well as method of maintaining the consistence for supporting the interactive modifica- tion. The efficient management software system of graphic element information can be developed by us- ing the proposed methods,
