VTKHDF-scripts

🔧 Custom Modifications

• Add the h5_dset_kwargs function in vtkxml-to-vtkhdf.py to compress the vtkhdf file. The chunk size will calculate automatically based on the data shape.

• Run vtkxml2vtkhdf.sh to convert files.

• Automatically put vtkhdf file in output/ dir.

• Add feature to convert time series data.

Note

Below is the original content.

Repository used to store h5py scripts to generate VTKHDF file format based on the file format specification.

Tutorial

An introduction to writing VTKHDF files can be found in Tutorial.

VTKHDF Generation scripts

scripts folder contains h5py scripts to generate VTKHDF File format. For now we can generate:

• PolyData
• UnstructuredGrid, with and without polyhedrons
• ImageData
• Overlapping AMR
• Composite Datasets (PartitionedDataSetCollection)
• HyperTreeGrid

Note that the script writing temporal data requires vtkpython.

vtkxml-to-vtkhdf

This folder contains a script named vtkxml-to-vtkhdf.py which converts VTK XML image data and unstructured grid, serial and parallel formats to the VTK HDF format.

We include a simple test script called test.sh that converts a file stored using each of the supported input formats into VTK HDF and then it checks the results. The script should not produce any difference with the stored baselines.

To be able to use this test.sh, it will be needed to clone the sample data repository : https://gitlab.kitware.com/keu-public/vtkhdf/vtkhdf-data-samples. An editing theses 2 variables:

• VTK_PYTHONPATH : for where your vtkpython is located
• VTKHDF_DATA_SAMPLES_LOCATION : for where the data samples repository has been cloned.

Note that to be able to use this test.sh, you will need to clone this repository which have
