VTK(Visualization Toolkit)是一个用于可视化和图形处理的开源软件系统。它提供了丰富的功能和工具,用于处理和呈现各种类型的数据,包括网格数据。 要读取网格单元的长、宽和高,可以通过以下步骤使用VTK进行操作: 导入必要的模块和库:import vtk 读取网格数据文件:reader = vtk.vtkUnstructuredGridReader() reader...

vtk中用vtkTecplotReader类读取外部文件数据(该文件数据可以用Tecplot打开并显示)。 主要流程是: (1)vtkTecplotReader读取外部文件, (2)vtkAppendFilter数据过滤, (3)vtkUnstructuredGrid过滤后数据转换非结构网格, (4)读取存储在cell单元中的结果数据: vtkSmartPointer ds = reader->GetOutput(); ...
