[Paraview] Mimicking the 'set view plane direction' GUI buttons in Python script

[Adriano Gagliardi]

Thanks for that. I'll give it a try today. I've executed the script using
the built python shell and what appears to be happening is my screen appears
as I'd like it, then almost immediately it resets itself to a standard view.
Here are the last few lines of my script:

//======================================
##set camera
cam = GetActiveCamera()

cam.SetFocalPoint( (point1[0]+point2[0])/2.0, (point1[1]+point2[1])/2.0,
point1[2])
foc = cam.GetFocalPoint()
print foc

cam.SetPosition(point1[0]*-50, foc[1], foc[2])
print cam.GetPosition()

cam.SetViewUp(0,0,1)

print cam.GetViewUp()
print cam.GetViewPlaneNormal()

cam.Zoom(10)

Render()
//=======================================

Is it possible Render() calls ResetCamera()?

I'm not quite sure this is available in 3.5, but there is a new way to set
camera properties.  Instead of setting them on the camera, try setting them
on the view:

view = GetActiveView()
view.CameraPosition = [-15, 10, 0]
view.CameraFocalPoint = [0, 10, 0]
view.CameraViewUp = [0 ,0, 1]

All settable properties for the view can be printed:

for p in view.ListProperties():
    if not view.GetProperty(p).GetInformationOnly(): print p
