[Paraview] How to export .x3d files from python script?

Thu Oct 31 17:32:42 EDT 2013

You should also have said you had a remote server that was doing remote
rendering.
This is the reason why your x3d is empty.
You need to do local rendering in order to get geometry locally so the
export will have something to export.
