[Paraview] zoom to data

[Tomislav Maric]

Hi Peter,

thank you so much for the help, it got me on the way, but I still have
some questions.

Here's what i've tried: 

    I didn't set wireframe, points , etc, and ResetCamera and
StillRender give me a black screen. I took your advice and did this:

view = servermanager.CreateRenderView()

camera = view.GetActiveCamera()

and then i played arround with camera.SetPosition() and camera.Zoom(),
and without setting the wireframe or anything else, I got the picture of
my data. Now I'm really puzzled. Why doesn't ResetCamera place my data
within the display window in the first place? 

And one other thing worries me: if I make any view change via the camera
object (i.e. camera.SetPosition(x,y,t)), any call to StillRender()
brings back the black screen. Still, if I save my data like this:

view.WriteImage ('pathNameOfMyData','vtkPNGWriter'), and afterwards call
StillRender() my data's back on the view window. 

Does it matter if I'm reading .vtk data from stand alone python
interpreter linked correctly to work with paraview modules?


Regards,
Tomislav
