图形技术在系统仿真中的应用

The Application of Graphic Technique in System Simulation

本文首先从应用对系统仿真提出的要求出发，讨论了图形技术在系统仿真中的地位及应用范围，然后着重介绍了系统仿真中的动画仿真和图形建模技术，提出了实现动画仿真和图形建模必须解决的关键技术问题，并结合ＩＭＳＳ给出了实现动画仿真和图形建模的一种方法。

In this paper, We first discuss the position and the application area of graphic technique in system simulation. By using graphic technique, the following objectives can be achieved: reducing the model developing time, changing the apperance of communication interface, and improving the simulation precision and efficiency. And then we introduce in detail the animation and graphic modeling technique in simulation. Animation is a visual method for showing model behaviour. Visual and vivid animation picture can not only verify if the model is correct, but also provide a powerful tool for people to observe the simulation process. It makes simulation results more convicible. So, lots of simulation softwares with animation function emerge one after another. There are two crucial problems in achieving simulation animation. The first is the correspondency of animation picture and simulation model. The second is the synchronism between animation and simulation. In the end of this paper, we give a method of achieving simulation animation and graphic modeling in IMSS (The integrated Manufacturing Simulation Software).
