Design of Launch Vehicle Test Data Management and Visualization System

摘要:

针对现有运载火箭试验数据管理及可视化系统依赖于第三方功能插件,未实现纯浏览器端三维模型渲染及交互,系统对运行环境依赖性强、部署和维护成本高等问题,设计了基于JavaScript框架ExtJS和WebGL框架three.js的运载火箭试验数据管理及可视化系统;首先基于B/S架构设计了系统总体框架,然后针对二维图形数据传输延迟问题设计了基于Web Worker的数据读取方案,最后针对浏览器端三维模型渲染需求提出了基于VTK模型的转换算法,设计了三维模型渲染及交互方案;试验结果显示,该系统不依赖于运行环境和功能插件,能实现浏览器端二维图形和三维模型渲染及流畅交互,为兼容国产化操作系统、降低部署和维护成本创造了条件。

Abstract:

The existing launch vehicle test data management and visualization system rely on third-party plug-ins,it can’t realize rendering and interaction of three-dimensional model in browser and rely on runtime environment.It can be very cost to deploy and maintain the system. A new launch vehicle test data management and visualization system is designed based on JavaScript framework ExtJS and WebGL framework three.js. First,the overall framework is designed based on B/S architecture,then the data read sheme is designed based on Web Worker to solve the problem of 2d graphic data transmission delay. The test results show that the system doesn’t rely on the runtime environment and plug-ins. It can realize rendering and interaction of three-dimensional model in browser smoothly,be compatible with our country homebred operating system and reduce the costs of deployment and maintenance.
