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

Thu Oct 31 12:27:19 EDT 2013

Oops, sorry about that.
So when I called
x3dExporter.SetView(RenderView2)
x3dExporter.Write()
the viewport turned green!
It looks like this means that the exporter's view is its output in some sense.
I need to plumb things up so the view goes into the exporter and out comes an x3dExporter.

Hi Rich,

Maybe the active view is not the one that has your rendering.
You may need to call SetView(RenderView2).

Arrgh!
I tried the following and the resulting file did not contain my isosurface as created by the below script.  What am I doing wrong here?  Sorry for the stream-of-consciousness posts here…

>>> exporters=servermanager.createModule("exporters")

>>> x3dExporter=exporters.X3DExporter(FileName="test.x3d")
>>> view = GetActiveView()

>>> x3dExporter.SetView(view) # <===== NEW LINE

>>> x3dExporter.Write()

… and immediately got the answer from google:  http://www.paraview.org/pipermail/paraview/2012-May/024921.html

However, I'm still curious as to how the person in question discovered how to do it.  Where is all the good python documentation/lore stored?  The wiki wasn't too helpful to me in that respect, i.e., as a reference, although it has a lot of good ideas/information.

I recorded a script to try to understand how to export a time series of an isosurface as .x3d files so I can muck with them using blender.  But when I look at the script, the crucial bit of exporting the .x3d did not get captured.  Is that part not scriptable?  How can I go about finding out for myself which file formats can be exported from python scripts, if any?
Thanks

Here is the script that got captured:
