摘　　要：OpenGL Performer是一款专业的3D图形开发包。该开发包由各个不同的功能开发库组成。为了解决OpenGL Performer应用程序的"实时性"和"逼真度"之间的矛盾,获得流畅的渲染效果,需要对应用程序的开发进行优化。OpenGL Performer视景优化的关键方法有:单管线运行、实时场景统计、不可见面裁减、DVR保持帧率、LOD管理等。这些方法的应用将在很大程度上减轻运行系统的载荷,达到图形图像快速绘制的目的,获得较好的视景仿真效果。OpenGL Performer is a professional SDK for 3D graphics,and various functional libraries are included in it. In order to achieve free-running effect in OpenGL Performer applications hy solving the conflict between ＂real- time ahility＂ and ＂fidelity＂, the development of program needs to be optimized. Some key methods in OpenGL Performer scene optimization are： single pipeline rendering,real- time statistic, culling unseen faces, maintaining frame rate using DVR, LOD management, etc. System stress can be remarkably lightened with the application of these methods. In this way, the goal of fast rendering of graphics can be achieved, while excellent effect of visual simulation can be attained.
