I don't think VTK has any built-in support for HDF5 per se. It does have
support for XDMF, which uses HDF5 for the "heavy data".

For our use case (volumetric data), we wrote our own simple
vtkImageAlgorithm to read our custom HDF5 based volume format. It uses the
regular HDF5 library from the HDF Group.

I think that's the approach you need to take with VTK if you have some
custom HDF5 based format.

Hope that helps,
