对三种常用视景仿真软件的功能比较研究

该文首先对OpenGL，DirectX，OpenGVS三种图形仿真技术的概况进行了简单的介绍；然后对它们的主要功能进行了叙述；最后根据多年从事图形仿真的经验，分析了每种仿真技术的优缺点及适用范围，给出了如何选择图形仿真软件的基本原则：即如果做游戏和交互式多媒体开发多选择DirectX；如果做某一过程的图形可视化仿真应首选OpenGVS，因为该技术相对OpenGL简单，易学、易用；而如果要求高精度的图形应用程序时，虽然应用比较麻烦也应使用OpenGL；或者根据实际情况可将OpenGVS和OpenGL或OpenGVS与DireetX综合应用以达到逼真、形象、实时的仿真效果。

Function Comparison of Three Current Graphic Simulation Softwares

The functions of three current graphic simulation softwares such as OpenGL, DirectX and OpenGVS that mainly applied in PC are discussed. Then, this paper shows respectively the advantages, shortcomings and applying fields of these softwares. Finally, it presents an advice of how to select the computer graphic simulation software based on the application status and conditions. If developing game or multimedia software, you should use DirectX; if you want to make visualization simulation, you should apply OpenGVS which is easier than OpenGL; however, if you want to get higher precision, you had better to use OpenGL and you also can synthetically apply OpenGVS, OpenGL and DirectX to get the reality, visualization and real - time effect.
