param3d_vtk

python vtk example files for vtk data manipulation

The repository contains examples files in the 'ex' and the 'insitu' directory, and a bunch of simple python files to expose some usage of vtk function, 'open', 'manipulate', 'visualize' and 'save' vtk files.

VTK object used

• vtkUnstructuredGridReader => read VTK data
• vtkUnstructuredGridWriter => write VTK data
• vtkArrayCalculator
• vtkAppendFilter
• vtkThreshold

examples files

param3d_info.py

Read data and look at the different array cell information

• vtkUnstructuredGridReader

param3d_visualize.py

Read and visualize data

Read VTK data

• vtkUnstructuredGridReader

Visualization

• vtkDataSetMapper
• vtkActor
• vtkRenderer
• vtkRenderWindow
• vtkRenderWindowInteractor

param3d_merge.py

Read a list of files, and merge then in a single one

• vtkUnstructuredGridReader
• vtkAppendFilter
• vtkUnstructuredGridWriter

param3d_calculator.py

Read a simple file, copy and translate the cells while adding a new array (with 2 different values for color visualization). The calcultator is used twice: i) to add an array, ii) to translate the cell (change the coordinates)

• vtkUnstructuredGridReader
• vtkArrayCalculator
• vtkAppendFilter
• vtkUnstructuredGridWriter
• => visualization

param3d_split.py

The example file contains 2 cells with a 'label' array containing a single value per array. The Threshold is used to extract and save each cell.

• vtkUnstructuredGridReader
• vtkThreshold
• vtkUnstructuredGridWriter

param3d_threshold.py

The example file contains 2 cells with a 'label' array containing a single value per array. The Threshold is used to extract visualize a one of them.

• vtkUnstructuredGridReader
• vtkThreshold
• => visualization

param3d_extract2.py

Extract cells from an example file and add data as a new array before saving it.

• vtkUnstructuredGridReader
• vtkArrayCalculator
• vtkThreshold
• vtkUnstructuredGridWriter
