电磁场与力场耦合仿真系统的可视化技术

科学计算可视化把由数值计算获得的大量数据以图像的方式表示出来，使抽象的数据内容及相互关系变得形象直观。OpenGL是一个功能强大的图形库，支持可视化实现的语言，在可视化的研究和开发中得到广泛的应用。该文以一个科学计算可视化软件一一电磁场与力场的耦合仿真系统为例，首先描述了整个系统的总体框架，然后着重介绍了OpenGL在其可视化开发过程中的应用，详细阐述了可视化仿真部分用到的三维实体建模、交互操作、字符显示、动画及双视口等关键技术。

Visualization of Electric Magnetic Field and Coupling of Force Field Calculation and Simulation System

Visualization in scientific computing displays a large amount of data, which come out of the calculation by number value, by means of pictures. And it can make the abstract data and the relation among them easy to be analysed. OpenGL is a powerful graphic library. It is a kind of computer language which can realize visualization and is widely used in the research and development of visualization. Regarding the electric magnetic field and coupling of the force field simulation system as an example, which is a software about visualization in scientific computing, firstly ,this thesis describes the whole frame of the system . Then it introduces how is OpenGL used in this system and expounds the key technologies, such as 3-D object construction, mutual operation, character display, animate and a couple of view port,etc, used in visualized simulation.
