Forgive my misconception before! I am baffelt by how this work!<br><br>I looked closer. I see plane source on my imput is empty! bounds 1 -1 ... on all process except 0... so that answer something! before this I suppose that the source must be duplicate on all process, because the class doc for vtkPStreamTracer say thaat this must be so. Now I will like to know how does filter such as distributed stream tracer work in this case (plane source is empty on all imput except 0)? Web doc day seed points must be the same across on all process? Can we explain how paraview works here?<br>

Have some issue with a filter that operate on plane source when run with more than a single process. Plane source on imput seem to be duplicated identical on all processes (no problem), then my filter run and make a shallow copy of the source and pass to output (problem start!). In the spreadsheet view I see more points than I should in the output, + I add point data I see more point data as well, I explore with spreadsheet view show that unexpected point data all duplicate of expected.<br>
<br>My question, how paraview handle source duplicated on all process? How paraview can know that the data is duplicate for plane source? How does it render such duplicate data? I seek to add some point data to plane source and provide on the output. What I need to do in the filter to avoid the issue?<br>
