基于opengl的虚拟视景仿真系统研究与实现

摘要

In order to design efficiently simulated a variety of visual simulation design tasks, based on OpenGL, designed and implemented a universal virtual scene simulation system. System using object - oriented technology packages visual resources, through the visual interface, organizes visual resources into scene graph organization and completes visual simulation tasks. System can dynamically load three - dimensional models, provides random terrain and DEM terrain interface and builds vividly visual simulation environment. Meanwhile, simulation results can also be saved in the form of video. The system has been proved to be universal and flexible, significantly reducing development cycle.%为了使仿真设计用户快速高效地设计多种视景仿真任务,基于OpenGL,设计并实现了通用的虚拟视景仿真系统.系统采用面向对象技术将视景资源封装,通过可视化界面,将各种视景资源用场景图组织,完成视景仿真任务.系统可以动态的载入三维模型,提供随机地形和真实地形接口,构建逼真的视景仿真环境.同时,还可以将仿真结果以视频的形式保存,脱离系统环境演示.经验证,系统具有一定的通用性和灵活性,极大地缩短了视景仿真任务的开发周期.
