<p>I have a parallel source which generates Structured Grids.
<u></u><u></u></p>
<p><u></u> <u></u></p>
<p>When each process generates its piece, I am very careful to ensure that the WholExtent is correct (in this case 0,31, 0,31, 0,31) and individual pices are within this extent. I have replaced the PieceToExtentTranslator in the pipeline
with a kind of TableExtentTranslator. I don’t believe that is the cause of my trouble, but when downstream filters consume the data and they in turn are updated, I get messages like this. (image embedded). the update extent is not within the whole extent.<u></u><u></u></p>
<p>The Whole Extent has been set to the piece extent. But I can’t find where this is happening. Somewhere in the pipeline, my WholeExtent is being Replaced with the piece extent.<u></u><u></u></p>
<p><u></u> <u></u></p>
<p>I can avoid these annoying messages by setting <u></u><u></u></p>
<p>outInfo->Set(vtkStreamingDemandDrivenPipeline::UNRESTRICTED_UPDATE_EXTENT(), 1);<u></u><u></u></p>
<p>which stops the pipeline displaying errors and all behaves properly, but I’d like to stop this happening at all.<u></u><u></u></p>
<p><u></u> <u></u></p>
<p>Can anyone tell me where the WholeExtent is being reset in the pipeline (or a good place to look). I’m flummoxed.<u></u><u></u></p>
