<div dir="ltr"><div><div><div>Hi Hong,<br><br></div>I don't think you want to do VTK Python wrapping of your class. What you want is to have the proxy to the filter Python wrapped such that it's available when you import paraview.simple. This is what's needed for Catalyst Python pipelines. I don't think you're properly initializing the plugins from the previous directions I sent. You may want to look at <a href="http://public.kitware.com/pipermail/paraview-developers/2013-September/002499.html">http://public.kitware.com/pipermail/paraview-developers/2013-September/002499.html</a><br>
<br></div>As a side note, the gradient of unstructured data set filter can compute vorticity as well. It does require a vtkDataArray with three components to use though. <br><br></div>Regards,<br>Andy<br><br></div><div class="gmail_extra">

<br>
ADD_PARAVIEW_PLUGIN(SMVorticity "1.0"<br>
SERVER_MANAGER_XML VorticityFilter.xml <br>
SERVER_MANAGER_SOURCES VorticityFilter.cxx)<br>
<br>
<font color="FF9900">target_link_libraries(SMVorticity ${deps})</font><br>
<br>
<font color="FF9900">if(VTK_WRAP_PYTHON)<br>
wrap_python(SMVorticity "${sources}")<br>
endif()</font><br>
-----------------------------<br>
<br>
The orange lines are added by following <a href="http://www.paraview.org/pipermail/paraview/2012-May/024855.html" target="_blank">
http://www.paraview.org/pipermail/paraview/2012-May/024855.html</a> which works well and builds my filter and also wraps it in Python (i.e., it generates libSMVorticity.a and libSMVorticityPythonD.a). I have also verified the plugin is indeed loaded into pvserver
and pvpython in paraview built bin directory.<br>
<br>
However, I still got "name not defined" error in coprocessing script when creating this filter by name "VorticityOfUnstructuredDataSet" in python script. I have a couple of specific questions I am currently investigating and hoping to get some inputs from experts
in the list:<br>
<br>
1. I am not sure where this name "VorticityOfUnstructuredDataSet" (exported by coprocessing script generator plugin) comes from, the only clue I can see is in plugin.cmake, where the plugin is specified with DESCRIPTION "Vorticity Of Unstructured DataSet" and
in VorticityFilter.xml, where the plugin is given a label of "Vorticity Of Unstructured DataSet." Should this name be defined somewhere such as in some python file in paraview python site-packages?
<br>
<br>
2. I did try to add PV_PLUGIN_IMPORT macros to the adaptor since I am using Catalyst, however, the plugin symbol "pv_plugin_instance_SMVorticity" is undefined in the adaptor static lib (the same plugin symbol is defined in pvserver), hence I got an undefined
error when linking simulation code to the adaptor. I did try to add my plugin static lib (in which the plugin symbol is defined) to the adaptor target via target_link_libraries before linking to vtkPVPythonCatalyst, but that does not seem to take any effect.
For some reason I am still investigating, my plugin lib does not get to link to the adaptor via target_link_libraries. What I did is to go to src directory in the cross target and modified CMakeLists.txt for PhastaAdaptor, then went to corresponding paraview-build
directory, and did "make clean" followed by "make" to rebuild PhastaAdaptor lib. Is there something obvious that I did not do correctly?<br>
<br>
Thanks for any inputs!<br>
<br>

<div>Can you share your plugin or at least the CMakeLists.txt for your plugin? Have you tried with any other plugins that get packaged with ParaView to see if they work?<br>

If you're using Catalyst, I would suggest adding in the PV_PLUGIN_IMPORT_INIT<span>

custom filter plugin to be loaded and wrapper into python module? I see "LoadPlugin" function defined in simple.py to call servermanager.LoadPlugin(filename, remote) which I am thinking perhaps should be called to load my plugin before my python coprocessing
script is executed, but not sure whether this is the case or not. <br>

<p class="MsoNormal"><span>Otherwise Andy is right. Putting the filter inside a plugin a good way to go. The plugin infrastructure will make it so that when you provide the XML that describes your vtk class, ParaView's build system will automatically wrap it
into a proxy and python class so that ParaView will be able to use it.</span></p>

I set up a pipeline that used a custom filter I developed and exported it as a python script for coprocessing. I have made sure the static library for my custom filter is built and available in paraview-build/lib directory, and I have also linked this custom
filter static library along with Catalyst libs to the simulation code for coprocessing. However, when I run the simulation linked with ParaView coprocessing for in-situ visualization, I got "NameError: name 'MyCustomizedFilterName' is not defined" error when
the line of my customized filter in my python coprocessing script is read in for pipeline coprocessing. What should I do to get my custom filter wrapped in python so that it can be recognized and used as part of the python pipeline script for coprocessing?
Any advice and suggestions are very much appreciated.<br>
