[Paraview] SurfaceLIC and python interface

[Albina, Frank]

Hi Sebastien!

Thank you very much for the invaluable information. I had found on the internet the following PV bug: http://www.paraview.org/Bug/print_bug_page.php?bug_id=12360, which shows that you have to load the plugin for both server and client when running pvbatch. I had to find the hard way that loading the plugin for the server only does not work. BTW, when loading the plugin for both server and client, I get the following warning messages:

Warning: In /cfdcode/opt/ParaView/SRC/paraview-3.14.1/ParaViewCore/ServerManager/vtkSMProxy.cxx, line 889
vtkSMPVRepresentationProxy (0x1a51fe0): Proxy SurfaceLICRepresentation already exists. Replacing

vtkPVCompositeRepresentation (0x7184cc0): Replacing existing representation for key: Surface LIC

The same happens with the PV binaries downloaded from KitWare. The platform is x86_64 running under SLED10 Linux.

However, loading the plugin and using the C++ API works just fine.

Thanks again.

Cheers,

Frank.

Hi Frank,

I think you need to use the C++ API as the representation was already
wrapped based on another type of representation that was not providing
those properties

Here is an example on how to set one of your property.

DataRepresentation1.SMProxy.GetProperty('LICIntensity').SetElement(0,1.0)

Alternatively, when you load you plugin, you can try to provide your
globals as argument. That might solve the problem too.

LoadPlugin('file', True, globals() )
