[Paraview] Is the VIEW-UP vector updated automatically?

[Kazuyoshi Furutaka]

Dear ParaView expert...

I'm using ParaView Version 4.2.0 32-bit on linux (Fedora 20,
i386).

Is the view-up vector updated automatically after
e.g. changing the camera position?

>From Python Shell, I got the following result:

...resetting...
Python 2.7.5 (default, Sep 25 2014, 13:58:10) 
[GCC 4.8.3 20140911 (Red Hat 4.8.3-7)] on linux2
>>> from paraview.simple import *
>>> box=Box()
>>> Show(box)
<paraview.servermanager.CompositeMultiSliceRepresentation object at 0xad91dcc>
>>> cam=GetActiveCamera()
>>> cam.SetPosition(0,3,3)
>>> Render()
<paraview.servermanager.SliceView object at 0xad91bac>
>>> cam.GetViewUp()
(0.0, 1.0, 0.0)
>>> 

Is this correct behavior?
Who/what routine/method is responsible for updating the
vector?

I'm observing a curious behavior of paraview.simple.Azimuth();
camera is NOT moving left/right.

Thanks in advance.
