[Paraview] Displacements

[Cory Quammen]

In the "Load State Options" dialog, you will definitely want to use
the option "Search files under specified directory". On Windows, the
directory should be

C:\Program Files\ParaView-...\data

where the ... depends on the exact version of ParaView you installed.

Should i think to write a python filter or is there already a filter that can do this?
