计算机辅助造船集成系统中的图形平台

A GRAPHICS PLATFORM FOR COMPUTER AIDED SHIPBUILDING INTERGRATED SYSTEM

计算机辅助造船集成系统二期工程ＣＡＳＩＳ－Ⅱ的图形平台，给设计人员提供了在产品概念上进行交互设计的图形环境，而不必理会点、线、圆等抽象的图形概念，对产品信息模型在大型应用系统中的实际应用和新型ＣＡＤ系统的建立作了初步的探索和尝试。文中叙述了船体结构产品信息模型，建立在这个产品信息模型上的图形平台的总体设计，基本功能和应用开发策略。

A graphics support platform for Computer Aided Shipbuilding Integrated System (CASIS) is presented. It provides designers an interactive graphics environment on the concept of product not on the graphics elements of point, line, are, circle etc. An exploration of using a product model in an engineering application is niade and an experimental system, a new type CAD system, is established. The product model of the ship structure is illustrated, on which the platform is created, and the main idea, functions of this platform are described. The strdtegy of application development based on this platform is discussed also.
