摘要
飞机座舱显示系统已经由传统的二维显示发展到多维显示方式,VAPS XT作为一种辅助人机界面设计工具,可以提高显示界面的设计效率,但其并不直接支持对三维显示界面的开发。提出了一种对VAPS XT进行二次开发的方案,可以在基本的VAPS XT配置模式下,利用Open GL库和DEM高程数据开展基本的三维视景仿真设计,可以实现在VAPS XT环境下的三维视景开发。对利用VAPS XT开发三维视景的流程进行介绍,包括VAPS XT的二次开发过程、三维高程数据库的处理、坐标变换和地形渲染的基础,可以作为驾驶舱人机界面开发的一种新模式。仿真结果证明该方法是一种有效便捷的三维视景仿真验证技术。
Aircraft cockpit display system has developed from traditional 2D to multi-dimensional display mode. As a human-computer interface development tool, VAPS XT can improve the design efficiency of cockpit display, but does not support 3D display design directly. We proposed a scheme for second development of VAPS XT, which supports basic 3D cockpit display simulation design with default VAPS XT configuration by use of Open GL library and DEM elevation database, thus to realize 3D cockpit display development with VAPS XT. This paper introduces the development process of 3D cockpit display with VAPS XT, including the user development process, data processing of 3D terrain database, coordination transformation, and foundation of rendering process. The whole process can be applied as new way for cockpit human-machine interface development. The simulation result shows that the process is an effective and convenient verification technology for 3D cockpit display design and simulation.
