[Paraview] Python Scripting - Acess vtkOpenGL cameras from .pvx files information

[Léo Pessanha]

Hi!

I would like to know if there's a way to acess the information/attributes
of the cameras there are created trough a .pvx file

To acess the attributes in the camera of the active Layout/RenderView  I do:

1 - Open Python Shell
2 - camera = GetActiveCamera()
3 - print(camera)

And the output is:
