I ran into an issue while performing the migration described here:<br><br><a href="http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Removal_of_Methods_for_Manipulating_Update_Extent">http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Removal_of_Methods_for_Manipulating_Update_Extent</a><br>
<br>In VTK 5<br><br>void vtkDataObject::SetUpdateExtent(int piece, int numPieces, int ghostLevel) executed:<br>{<br> ...<br> sddp->SetUpdateExtent<br> (sddp->GetOutputInformation()->GetInformationObject<br>
(this->GetPortNumber()), piece, numPieces, ghostLevel);<br> ...<br>}<br><br><br>In VTK 6<br><br>void vtkAlgorithm::SetUpdateExtent(int port, int connection,<br> int piece,<br>
int numPieces,<br> int ghostLevel)<br>{<br> ...<br> vtkStreamingDemandDrivenPipeline::SetUpdateExtent(<br> this->GetInputInformation(port, connection),<br>
piece,<br> numPieces,<br> ghostLevel);<br> ...<br>}<br><br><br>In VTK 5, the output information is used, in VTK 6, the input information is used which results in incorrect behavior.<br><br><br>So I am now using code that looks like this:<br>
<br> aFilter->UpdateInformation();<br> vtkStreamingDemandDrivenPipeline::SetUpdateExtent(<br> aFilter->GetOutputInformation(0),<br> pieceIndex, numberOfPieces, ghostLevel);<br><br><br>Another question- is it by design that you must call UpdateInformation() before SetUpdateExtent()? If you fail to do so, the information set by SetUpdateExtent() will be erased. I have found that the actual requirement is that you must call calling aFilter->GetOutputDataObject(0) which forces a call to GetExecutive()->UpdateDataObject() to initialize the output information.<br>

I don't have any objections to expanding this guide to include modularization as long as I am not asked to do it :-)<div class="HOEnZb"><div class="h5"><br><br><div class="gmail_quote">On Tue, Apr 10, 2012 at 6:45 PM, Pat Marion <span dir="ltr"><<a href="mailto:pat.marion@kitware.com" target="_blank">pat.marion@kitware.com</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">With the recent merge of the new modular build system, I suppose we should expand this guide to cover all the build system changes? For example, libraries have been renamed, python modules renamed, default install directory has changed, the vtkstd namespace and headers are removed... is this wiki page the best place to accumulate these items?<br>
