摘要
为提高三维战场态势显示标绘的图形效率和人机交互性,在总结分析战场态势信息基本理论概念的基础上,通过对显示与标绘两方面的军事需求和OSG/Qt结合使用的软件架构模式进行分析,提出了程序框架的线程模式优化方法和基于帧缓存对象的离屏纹理烘焙技术的军标符号显示生成算法。设计和实现了三维战场态势显示标绘软件模块,并对模块进行了多种实现方法的比较测试,检查验证了相关技术方案和关键技术对于提高系统绘制效率和人机交互的有效性。
This paper proposes an optimization method of thread mode for OSG/Qt framework and a generating algorithm for military standard symbol display using off-screen render to texture technology based on frame buffer object, to improve the display efficiency and human-computer interaction of three-dimensional battlefield situation display and plotting. The basic concept of battlefield situation information was summarized, and the military demand of display and plotting and OSG/Qt architecture were analyzed. On this basis, the software module of three-dimensional battlefield situation disp!ay and plotting was designed and tested to verify the plotting efficiency and the human-computer interactiveness of the solution and key technology.
