用OpenGL开发交互式三维化工场景仿真工具

根据化工场景的视景特点,从面向对象方法论、分布式处理概念出发,研究了如何开发具有真实感的化工场景的动态交互式三维编辑、仿真程序。提出了化工场景图元的类体系框架结构、消息扫描策略、动态交互的“二维拾取”概念以及分布处理的设计。给出了在Windows 95/NT、VC ++开发环境中利用OpenGL开发的设计思想和实现方法。

Developing interactive three-dimensional simulation tools with OpenGL for chemical engineering scenes

In the light of visual characteristicsof chemical engineering scenes, this paper studies on the development of three-dimensionaland dynamically interactive editor and simulation programs with reality for chemicalengineering scenes based on the object-oriented methodology and the concept of distributedprocessing. Te architecture of figure class library for chemical engineering scenes, themessage sweeping strategy, the idea of dynamically interactive “two-dimensional pick-up” and the design of distributed processing are put forward.The thinking on design and its implementation method for this development with OpenGL inWindows95/NT and VC++ environments are also given herein.
