摘　　要：针对大规模三维视景仿真中同时对场景全局和各目标模型细节观察的需求,设计了一种基于OpenGL的主辅式多视口场景渲染结构。通过对OpenGL视口定义、深度检测及投影变换等技术的灵活应用,该多视口结构在“导弹突防三维视景仿真系统”中得到了实现,有效地解决了多观察点同时兼顾的问题。Considering the needs of observing the whole sight as well as the details of model target in large-scale 3D visual simulation, the ＂main-assisted multi-view-ports structure＂ based on OpenGL is designed. By flexibly apply the tech of OpenGL view-ports definition, depth testing and projection changing, this multi-view-ports structure implemented in ＂3D visual simulation system of the missile penetration＂. The problem of observing the multi-view point at the same time has been settled.
