A Graphic Database for 3-D Geometric Moulding System
-
摘要: 一个实用的、完整的几何造型系统必须有一个精心设计的图形数据库作为图形信息的存 贮和管理中心.本文以几何体的边界表示法为基础,提出了一个几何造型系统的图形数据库 设计方法,并介绍了该方法在UNIFY关系数据库管理系统上的实现及C语言接口设计.Abstract: A practical stand-alone geometric moulding system necessitates a graphic database as its pictorial information storing and management kernel. The design method hased on the boundary representation of geometric objects is proposed for a geometric moulding system graphic database. Its implementation on the UNIFY relational database management is propoent system and the design of C language interface are illustrated.
