摘　　要：OpenGL与Windows窗口使用不同的坐标系统,但是在进行基于OpenGL的具有灵活和复杂图形人机交互的系统开发时,不可避免地要面临坐标转换的问题。为此结合军标系统项目的开发,采用理论和实践相结合的方法,首先分析了两种坐标的区别和联系,论证了坐标转换的具体公式,而后对实际的开发步骤进行了论述,对这一技术问题从根本上给予了解决,扩大了OpenGL的应用领域。The different coordinate system is used by OpenGL and Windows, but when the system with flexible and complicate graphic interface based on OpenGL is developed, the problem of coordinate transformations must be confronted. So the technology problem is studied from theory and practice, combined with the development of military marking system, firstly the different and relation of two coordinate system is studied , the transformation formula is discussed, secondly the program of development is discussed . so the technology problem is solved completely, application field of OpenGL is enlarged.
