基于OpenGL的地球/地图三维模拟软件设计

OpenGL作为现今开放的三维动画显示设计环境，以其高效快速，稳定可靠性在三维仿真领域得到广泛应用。而地球及地图视图的三维模拟又是现今游戏动画设计及GIS系统中重要的组成部分，本文便针对地球运动、地图显示及空对地波束指向位置及范围，用VC／MFC的文档/视类结构。C＋＋类的面向对象技术，以OpenGL作为图形开发平台，设计了广泛通用的动画演示软件，为游戏及GIS系统设计人员提供了一定参考及指导意义。

Design of the 3-D earth simulation software based on OpenGL

OpenGL is the open 3-D graphic display design environment,and it is widely applied in the(3-D) simulation area for its efficiency and stability. However,the 3-D simulation of the earth and map is the key part for the design of the animation and GIS system.According to the earth movement,map display and the air to ground wave direction position and span,the simulation software is designed by VC/MFC and its document/view structure,oriented object method and OpenGL graphics development platform.The design supports the game and GIS system designer some reference and guidance.
