飞行模拟器视景系统的设计与实现

Design and Implementation of Visual Simulation System in Flight Simulator

飞行模拟器视景系统是飞行模拟器的重要组成部分,和其它视景系统相比飞行模拟器视景系统具有其自身的特点,包括场景覆盖范围大、涉及的场景对象复杂、视场角较大、对虚拟环境模拟和系统实时性要求较高等特点。针对于这些特点以及整个模拟器应用对视景系统的要求,对飞行模拟视景系统的视景数据库、多通道组网结构以及仿真程序进行了设计,给出了基于Creator/CTS/VegaPrime实现整个系统的开发流程,并对系统实现中的关键技术,包括多通道同步技术、大场景数据库的调度和实时绘制技术、环境模拟技术等进行了较为深入的研究。整个视景系统应用于飞行模拟器平台,实现了对于飞行模拟视景系统特定功能和性能的要求,能够在保证实时性要求的前提下达到预期的视觉效果。

The visual simulation system is an important component of the flight simulator. And compared with other visual simulation systems, the visual simulation system in flight simulator has its own characteristics. Based on its characteristics and the requests of the whole flight simulator for the visual simulation system, the design about visual system database, multi-machine synchronization rendering network structure and system simulation program was discussed, the development progress and implementation method of the system were introduced based on Creator/CTS/VegaPrime, and some key technology during the system implementation, including multi-channel communication synchronization, the dynamic management and real-time rendering of large scene, virtual environment simulation, was explored. The visual simulation system is used in the flight simulator, produces the expected visual effects with the interactive speed and reaches the functionality and performance requirements on this system.
