[Paraview] Silhouette filter
Hello. Some time ago I used the Silhouette filter for ParaView to visualize geometry edges (not mesh but indeed *geometry* edges). But I've missed the file and cannot find it for download now... Would, somebody, please, share this filter or give the download link? As some other people do, I use ParaView 5.2 as a most recent version compatible with RDP (I don't know if it's important for the filter compatibility). Thanks. ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
Re: [Paraview] Volume average along 1-dimension
Hi ashton, Perhaps the python programmable filter is needed for a 1D average you want to achieve. I have attached a state file as a similar example that firstly generates the cross sections along the z-axis by cutting a volume and then calculates the averages on them respectively. I hope this will help.

[Paraview] Creating clips for multiple data sets
Hi, I'm trying to apply 5 clips to a number of different data sets. I tried selecting them, right-clicking, pressing Copy, then selecting a different data set and pressing Paste, but nothing happens. Am I doing something wrong? I then tried to record a trace and modify it, but I couldn't figure out how to create a clip for the currently selected dataset. I see that I need to specify the clip input like this: > clip = Clip(Input=) but I would like to create a clip for the currently selected dataset, without hard-coding its name in the script. Is it possible to do so? Sorry about the beginner questions, I didn't find the answers in the manual. Thanks in advance! Best regards, Lev Karatun. ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview

Felipe,
I can confirm this behavior, and I have filed a bug report here:

Re: [Paraview] [EXT] Re: Details of XML filter with lists of input arrays
Utkarsh, Thanks for that information - I have figured it out now. A few notes for others who are or will in the future follow this subject: The object of this exercise is to write a Programmable Filter that will put up a list of your Cell or Point variables and allow the user to select which ones to process at runtime. Say you wrote a Volume-Average filter which calculates volume-averaged values of variables. Now you can let your user select which variables to average at runtime- this could be helpful in a number of scenarios. 1. You need to include at least one property in your .py file, otherwise the translator is unhappy - you can delete it from your .xml file, though, if you don't really want it (I did!) 2. Make a pretty standard xml plugin .py file and run it through the python_filter_generator to turn your python into an xml plugin 3. The python_filter_generator knows nothing about the variable arrays so it is strictly a manual mod to the .xml file. In order to illustrate this, I have included both the .xml originally produced by the python_filter_generator (test.xml.orig), and the hand edited version where I implemented the Cell variable list and deleted the property which I included only to make the translator happy (test.xml). You can tkdiff these to see exactly what changes were made 3. The original python_filter_generator had a typo of vtkMultiblockDataSet, while this newest revision correctly has vtkMultiBlockDataSet - use the one in your .py file that matches the version of the generator you are using I have run this test filter on can2.exo, a good, simple multi-block dataset that is available to everyone. Screenshots attached Hopefully this will help the next guy.

You need manually modify the XML generated using [1]. I've attached script.xml with my modifications to add a new property for "Arrays". Also attached a state file that demos this filter (load state after lading the script.xml as plugin). Hope that helps.

[Paraview] Volume average along 1-dimension
Hi all, I have a 3D volume (xyz) with each point/cell having a corresponding value (velocity; this is a model of the crust and seismic velocity). I want to calculate a 1D average velocity profile along the z-axis (so at every depth average all the x-y velocity values). Any idea?
