[Paraview] Python paraview.simple: Zoom To Data?

[Nico Schlömer]

I see.
Well, ResetCamera() seems to deliver okay results only after Show()
has been called -- OpenDataFile() doesn't suffice.
Another misconception of mine was that CameraPosition and
CameraFocalPoint could be set to anything. My data files contain flat
surfaces in the x-y-plane, and ResetCamera() won't show anything if
CameraPosition==[0,0,0] and CameraFocalPoint=[0,0,1]. This, again,
makes sense. Setting CameraPosition to [0,0,1], for example, fixes
this.

ResetCamera() still leaves a wide border around the object. Is it
possible to rid of those, too?

Cheers,
Nico
