摘　　要：本文介绍作者研制的一套交互式三维图形系统GP3D,该系统具有完全消隐功能,它以面造型为主,提供了立体造型的功能,也可以按照用户要求产生简明的线模型图,为了便于进行交互式操作,以及完成图例的增、删、调用和各类变换,系统设计了灵活的数据结构。系统具有丰富的图形编辑功能和文件管理功能,用户以简单命令定义构造体素,用以组建复杂形体。系统具有良好的实用性、通用性和用户界面性能。A worhing version of the interative 3-D graphics program GP3D, designed and comp leted by the author is introduced in this paper. GP3D functions mainly as a surface modeller with full hidden-Line removel. It also has some of the characteristics of a solid modeller. Naturally it can produce wire -frame pictures if required. In order to create delete or transfer pictures easily, effective data structure is designed in the program. GP3d is with some powerful functions of picture editing and file manipulating. Users can create solid elements by using single commands and combine them into compound large objects ,and large objects into larger ones. The program is practical for various technical applications and is provided with good interactive feature.
