基于分布式数值模拟结果的可视化

VTK是一个基于对象的三维重建方面的软件系统,其应用日益广泛。在对数值模拟软件进行开发时,需要对曲线、等值线、三维场等结果数据进行可视化。文中将针对大规模分布式数值模拟时的实时可视化问题,通过客户端广播可视化信息,服务器分别用数值模拟结果进行计算得到VTK文件,并将结果传回客户端,客户端将得到的数据进行合并,最后对其进行可视化并得到切线图像。结果表明,该可视化方法可以在较少影响数值模拟过程的情况下实现实时可视化。

Visualization Based on Distributed Numerical Simulation Result

VTK is a widely used software system of 3D reconstruction based on the object. During the development of some numerical simulation softwares,the visualization of curve,contour and three dimensional data fields is needed. Focusing on the real time visualization problem of the large scale distributed numerical simulation,through the client broadcasting the visualization information into servers,these servers respectively use the numerical simulation results to generate the VTK file and the calculation results are returned to the client,the client will have to merge the data which is used for the visualization. The results showthat the visualization method which is less affected by numerical simulation process can realize real- time visualization.
