微机三维图形数据描述的数据库方法

A DATABASE METHOD OF CONSTRUCTING DATA FOR 3D MICROCOMPUTER GRAPHICS

本文提出一种用数据库方法来描述和组织三维图形数据的方法,设计一个用户接口,实现数据管理系统dBASEⅢ与BASIC图形应用程序之间的图形数据转换,充分发挥两种语言的优点。这种数据结构及其处理方法应用在微机三维图形显示上,已获得了很好的效果。

This paper introduces a database method for const-ructing and manipulating data so as to generate three dimensionalgraphics in microcomputer and the way for designing an interfacebetween database management system,such as dBASE Ⅲ,and BASIClanguage.Database management system is an effective way toorganize and manage the data,and BASIC language has better arith-metic capability and graphics processing functions.Their functionscan be made good use of in this method.The data structure hasbeen applied to develop 3D graphics displaying system,and hasgot a better effect.
