摘　　要：硬件技术和计算机图形学的快速发展,带动了机载座舱图形显示处理软件尤其是图形程序接口API标准化的发展,具有代表性的OpenGL标准在该领域占据着很重要的地位。在分析Mesa联合WindML实现VxWorks下OpenGL机制的基础上,总结了一种"软件模拟+硬件实现"的OpenGL库函数的实现方法,并在某型国产芯片平台的座舱图形显示处理模块中进行了验证。结果表明,方法对掌握座舱图形显示的标准接口软件核心技术具有一定的借鉴意义。The software, especially the API of graphic processing in airborne cockpit display system has the trend of standardization, within the development of hardware technology and computer graphic knowl- edge. OpenGL occupies an important position in the domain of display system. This paper summarizes a method of realizing the library functions of OpenGL, basing on the research of realizing library of OpenGL of VxWorks operating system using Mesa and WindML. A graphic display and processing module of cock- pit display system is made to validate this method at last. This method has a positive effect on increasing localization, independent intellectual property and kernel technique about realizing some important func- tion of API.
