VTKio 0.4.1

A simple package for converting data between VTK files (XML and HDF5) and NumPy arrays.

VTKio

A simple python package for reading and writing Visualization Tool Kit (VTK) files.

Supported features

Legacy ascii .vtk files are not supported and only the newer XML and HDF5 based formats are supported.

XML files can be written in ascii, base64 binary and appended base64 binary formats. This means all files remain valid XML documents. Support for reading and writing raw appended data is provided, but discouraged.

XML and VTKHDF files can also be read using the associated file readers.

Data is returned in appropriate VTK classes with arrays stored in numpy formats.

[!WARNING] VTKHDF files can only be opened in supported software.
For example, ParaView has full VTKHDF support in 5.13 and above.

VTK File Formats

All file formats have been developed based on VTK's documentation where the XML formats and newer VTKHDF formats are described in detail. Additional information can be found in Chapter 5 of the VTK Book.

Further information regarding the VTK data model can be found in the ParaView documentation.

Example datafiles can be found for various filetypes at the VTK Examples Repository.
