基于Vega的飞行视景仿真系统设计

在飞行视景仿真的仪表建模中,专用仪表设计软件或Vega的仪表工具存在开发成本、显示效果及系统扩展性等不足。鉴于此,研究了基于Multigen Creator/Vega的复杂飞行仪表模型的建模方法,介绍了飞行视景仿真系统的模块化结构及开发该系统所用到的关键技术。在所给出的关键技术中,详细介绍了如何设计及驱动Creator软件建立的仪表实体模型以及开发基于Vega的视景驱动程序,并给出了相关的程序代码。阐述了在三维场景中,如何实现飞行模型的运动及仪表模型各模块的精确显示。该系统可以比较真实的模拟交互式的飞行过程,提供了一个通用的仿真平台。

Visual Simulation Design of flight Based on Vega

In the special instrument designed software and Vega instrument tools for instrument modeling of the flight visual simulation, there are disadvantages in development cost, display effect and system scalability. In light of that, a simulation method for complex instrument model based on Multigen Creator & Vega was researched. A general modularized functional structure of the visual simulation flight system was presented, and the key technologies which were used for developing the system were given too. Among the key technologies, the method of designing and driving instrument model with Creator and programming the Visual driver based on Vega was shown. Also the code was attached. The principle of achieving the movement of flight model and the precise display of the instrument modules were proposed. The system can simulate the real-life interactive flight, providing a generic simulation platform.
