[Paraview] Writing a custom reader for PV

[Richter, Christian, Dipl.-Ing.]

Hi,

it is realy easy.
Feel free to use my existing readers as starting point (I would suggest the rigids_reader, because it extracts points in a given order from a special-format file)
https://github.com/richti83/ParaView_Reader_for_LIGGGHTS

Just change the classname in every file.
Than change the section where i skip the header and adapt the switch block to your needs in RequestData Method of liggghts_rigids_reader.cxx.

About time-varing files: I usually write every timestep in a single file (dump0.liggghts ... dump100000.liggghts) and than let the fileseries reader loop over them. (see liggghts_rigids_reader.xml about the connection between reader-core and fileseries reader).

Good Luck,
Christian.

Betreff: [Paraview] Writing a custom reader for PV

Hi guys,

For some days now, I have been trying to use data in PV from the XYZ file format, but there is a bug in the "XMol Molecule Files" reader <http://www.paraview.org/Bug/view.php?id=14203>.

How difficult would it be to write a reader for the data file you have (XYZ file format) ? The "XYZ Files" reader in PV doesn't handle time-varying data. How can one possibly make changes and fix the reader?

Thank you all,
Rohit.
