[Paraview] Python view

[Cory Quammen]

Hi Ian,

I'm glad to hear you are interested in the Python View.

I want to try out the python view for the first time, but I am not getting

Did you copy and paste the script examples into the "Script" window, or did
you load the example state file on the blog? I suggest loading the state
file because the script examples in the blog post are missing some imports
that are needed. The state file has the complete script - I just confirmed
that it works on the 4.3.1 64-bit Windows binaries. You will have to point
ParaView to the bluntfin.vts file when you load the state file, which you
can download from

The Script is an auto-update property of the Python View. As such, it is
executed any time the view needs to re-render. This includes any time you
edit the script and then click elsewhere in the GUI, resize the ParaView
window, etc. It should work to click on the Python View after you have
edited the script - think of it as a big Apply button :-)

Thanks,
Cory
