If you're confused, imagine how I feel! I had not considered the "magic command" theory. LOL
There are a bunch of things going on here, so perhaps I just need to try to keep things simple.
I simply tried the command that you gave me and the viewport turned green.
So I exited Paraview and tried to start over. I connected to the remote server and tried to run all the commands in my stack trace. How can I do this? When I open the Python Shell window and just paste commands into it, only the first command is executed. Do I have paste each line in separately and hit Enter after each one? That's a major PITA.
I tried clicking "Run Script" and opened the script. It gave me the error
>>> Traceback (most recent call last):
File "<string>", line 5, in <module>
NameError: name 'VisItMirandaReader' is not defined
This is presumably from the beginning of the script:
try: paraview.simple
except: from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()
plot_raw = VisItMirandaReader( FileName='/nfs/tmp2/rcook/miranda/IRM_512_r1/plot.raw' )
But if I just type these four lines into the Python Shell, they work fine.
Is there an easy way to do this?
My goal is to
1) read a miranda file
2) create an isosurface
3) iterate through time and each timestep save out an x3d file
This seems like it should be simple, but I'm not getting it, probably because I just haven't got a clue how to start. I figured the traceback would be the logical place to start, but I can't get Paraview to use its own output.

Hum I'm getting confuse.
the RenderView2 was the name of the var in your stack trace.
It is not a magic command.

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
