<p class="MsoPlainText">I have a parallel source which generates Structured Grids.

<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">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.<o:p></o:p></p>
<p class="MsoPlainText">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.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I can avoid these annoying messages by setting <o:p></o:p></p>
<p class="MsoPlainText">outInfo->Set(vtkStreamingDemandDrivenPipeline::UNRESTRICTED_UPDATE_EXTENT(), 1);<o:p></o:p></p>
<p class="MsoPlainText">which stops the pipeline displaying errors and all behaves properly, but I’d like to stop this happening at all.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Can anyone tell me where the WholeExtent is being reset in the pipeline (or a good place to look). I’m flummoxed.<o:p></o:p></p>
