基于OSGEARTH的国产航天三维仿真软件设计

Design of 3D Space Simulation Software for Domestic Platform Based on OSGEARTH

针对目前航天领域缺乏经过验证、能够可靠应用于全国产化平台的三维仿真软件,本文基于OSGEARTH设计和实现了一款国产航天三维仿真软件.通过地球影像和高程数据的差异化加载、场景树的优化构建、弹道数据筛选等设计策略,解决了在全国产化平台上进行三维仿真的可靠性和渲染效率问题,并得到了仿真实验的有效验证.

Now,space field lacks 3D simulation softwares that are verified and can be used on all-domestic platform reliably.We introduce some design strategies,such as differentially loading Earth image and elevation data,optimized build of scene graph,filtering of trajectory data,and so on.The proposed software can solve the reliability and rendering efficiency problems in 3D simulation on all-domestic platform.Some simulation experiments have been conducted to valid reliability and rendering efficiency.
