基于Open Inventor的航天可视化系统

基于场景的可视化仿真是航天系统仿真研究一个重要的方面和有效策略；该文对可视化及其应用作了深入的研究，并分析了一般意义的可视化系统的布局和建构，并结合航天器飞行目标的运动特性，参照STK软件的相关实践经验，将航天任务仿真计算和航天场景的可视化进行了分离，构建一套以场景仿真为核心的、具有可扩展特性的分布式航天任务仿真可视化的系统框架．最后利用Open Inventor实现了相应的三维可视化仿真系统；结果表明，该文提出的航天可视化仿真的框架及实现途径是有效的和可操作的，不但能够满足常规的航天任务可视化仿真，而且可以在此基础上设计实现比较专业的航天任务可视化仿真。

A Visual Aerospace Simulation System Based on Open Inventor

Scenario Simulation is an important part and an effective method for studying the simulation methods of Aerospace Simulation.In this paper,the course VISC(Visualization in Scientific Computing) and its experience are discussed,then the layout and constructs of the general visual system have been analyzed.Taking the content as a foundation,combining with the principle of spacecraft dynamics and the correlative practice experience of STK(Satellite Tool Kits),computation of the aerospace simulation and graphic display based on aerospace scenario are separated,and the architecture of Aerospace Visual Scenario-based Simulation System is built by Open Inventor.It is a distributed and extensible system by which 3D pictures are thrown out at last.An effective method of Aerospace Visual Simulation System is designed by the system which can meet the visual simulation requirements of routine aerospace missions and the professional ones.
