[Paraview] xdmf polydata-points (particles)

[Jens]

Hi,

I am using xdmf-file-format for my structured grid to visualise
turbulent flows.

Now, I have a bunch of vectors not connected to that grid, but defined
somewhere between the grid-points. They are stored as float-XYZ
+xyzLength in my hdf5-file (you could think of particles with
attributes,too.)

Therefore I need to add polydata-points+attributes to my xdmf-file. Is
that possible? And if yes, how?

Greetings
Jens
