[Paraview] [EXTERNAL] Zoom in/out

[Scott, W Alan]

One set of ParaView tutorials is here:  https://www.paraview.org/Wiki/SNL_ParaView_4_Tutorials.

In the one ParaView and Python, the command is given,  with supporting python.  https://www.paraview.org/Wiki/ParaView_and_Python

I believe you are looking for the “Dolly” command.  So,

Control the camera
We want to move the camera.
First, get the camera and reset the camera to a known good position.
camera=GetActiveCamera()
camera.SetFocalPoint(0,0,0)
camera.SetPosition(0,0,-10)
camera.SetViewUp(0,1,0)
How to move the camera closer or further away
camera.Dolly(10)
Render()
camera.Dolly(.1)
Render()

Hello,

Is there any python script to zoom in by some percent? I tried to create one myself but it fails to zoom in correctly.

Best Regards,
Rustem.
