| 摘 要： | 为解决FAST基地可视化的问题,开发了一套基于OpenSceneGraph(OSG)与Qt的三维场景仿真系统。通过三维建模,计算机程序自动化布局,OSG虚拟场景搭建等,将FAST的场景进行仿真显示。通过数据驱动实现对虚拟场景的实时更新,同时采用OSG的粒子系统来模拟雨雪天气特效场景。该系统将FAST的场景实时显现在技术工作人员面前,具有场景漫游,动态演示等基本人机交互功能,可为FAST基地的实践工作提供辅助决策依据。

| Abstract: | In order to solve the problem of visualization of FAST,a 3D scene simulation system based on OpenSceneGraph(OSG)and Qt is developed.Through 3D modeling,computer automatic layout,OSG virtual scene construction,etc.,the FAST scene was simulated and displayed.The real-time update of the virtual scene can be achieved through data driving.The OSG particle system was used to simulate rain and snow weather special effects.This system displays FAST scenes in real time for technical staff,and has basic human-computer interaction functions such as scene roaming and dynamic presentation.It can assist the practical decision work of FAST. |
