<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal">I have a dataset which contains cell data for which I’m generating streamlines via vtkStreamTracer.<o:p></o:p></p>
<p class="MsoNormal">I then pass this through a vtkTubeFilter. Up to this point, all is well.<o:p></o:p></p>
<p class="MsoNormal">The next step in the pipeline is passing this through a vtkDataSetSurfaceFilter.<o:p></o:p></p>
<p class="MsoNormal">Then I pass the output through a vtkPolyDataNormals filter and this is where the problem seems to occur.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The output of the vtkPolyDataNormals filter hasnew cells that were created during
<o:p></o:p></p>
<p class="MsoNormal">the execution of the vtkPolyDataNormals filter which didn’t seem correct.<o:p></o:p></p>
<p class="MsoNormal">Looking at the code, I think it is only copying the input cell data.<o:p></o:p></p>
<p class="MsoNormal">This causes problems when I try to query the output polydata.
<o:p></o:p></p>
<p class="MsoNormal">For instance, which original cell was a cell in the output generated from?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Anyone have some ideas on why vtkPolyDataNormals would create new cells?<o:p></o:p></p>
<p class="MsoNormal">My understanding was that it would only create new points where it needed to split<o:p></o:p></p>
<p class="MsoNormal">edges based on the split feature edges setting and the angle specified.<o:p></o:p></p>
