Hey there Lucas,
really great work! I love to see the activity in vtk to work with hdf5, especially for AMR and I am looking forward to use it for postprocessing our code.
From a user perspective, do you know how your changes will be included in releases further downstream? Changes in vtk Master probably with the next release (9.3.1 or 9.4.0, hopefully soon?). Will ParaView receive an updated vtkhdf reader after the vtk release or already with it’s own upcoming release?
For the future work I would love to see a hdf implementation of Treegrid / Hypertreegrid Data. I believe that coupling that with a hierarchical functionality for uniform grids as blocks within the Treegrid would greatly benefit many Block-based AMR codes for their visualization.
Greetings,
Julius
