How is your data produced? We are developing a custom ParaView
application, and as part of that we are adding some new readers to VTK
to support S/TEM tomography using an HDF5-based format. The spec is
here,

It would be great to understand your needs, and whether some of this
development work could be tweaked in order to address a wider range of
experimental data that might help your user community. If XDMF is one
path, then we should also look more closely at supporting that too.

Thanks,
