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.

Dennis, Oops sorry, it slipped my mind you were doing this for programmable filter. It should be doable, but I'll need to dig -- don't remember of the top of my head.

Utkarsh, I think you have me confused with a real programmer! ;- ) I am just trying to write a Programmable Filter in python and I'm lost. I want to write an xml plugin that will put up a list of all the cell variables and let the user select from then and then have the names of those variables available in my python script within the Programmable Filter.I'm hoping this can be similar to plugins I have written with hardcoded variable names where I've used something like: Properties = dict( Sector_Angle = True) def RequestData(): def process_block(block): # # if (Sector_Angle): Maybe this isn't possible at this low level, but how would I put up the list and then what would I have in my RequestData script that I could branch on.

Utkarsh, So, for the first example we have: <<<<<<<<<<<<<<<<<<<< I get that the InputTypeDomain links it to cell arrays! - thanks for that.

Re: [Paraview] [EXT] Re: Details of XML filter with lists of input arrays
All, To be more exact, I wrote a routine here that does an area-weighted average of some variables.Now the users are asking if I can give them a list of variables in the model and they can choose which ones to calculate a weighted average.I can envision a Custom filter where I have a Programmable filter which processes everything, preceded by a Pass Arrays filter - I could bundle them together and expose the Pass Arrays filter to let them choose which variables they want, but I think the self-contained plug-in which I can add to the site Plugin directory and get automagically loaded at startup is a better way to go if I can just figure out how to do it!
