[Paraview] Writer plugin?

[Biddiscombe, John A.]

David

I used to make my writers the same as filters and even allow them to shallow copy their input to the output. Then in paraview they can appear in the filters menu and can be inserted in the middle of a pipeline and each time a render is activated, the writer would be triggered. (I used it for saving particles out from animations of advected flows). (you can check if the timestep has changed or other stuff is different and skip writes if necessary).

Adding the writer as a filter is an easy option!

Subject: [Paraview] Writer plugin?

Hi all,

I have a ParaView plugin that contains a new writer which I would like to expose. However, while the plugin does properly expose a new view and representation, the writer does not appear to get added (when I try to save a vtkTable such as a statistics filter output, it doesn't appear as an option).

1. Is there any documentation for adding writers in plugins? This page has a comment or two but doesn't appear complete:

    http://www.paraview.org/Wiki/ParaView/Plugin_HowTo

2. If you're willing to look over the XML, I've attached it below. See any mistakes?

	Thanks,
	David
