<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal">I have a strange issue and I’m not sure if it is my data or a limitation I wasn’t aware of.<o:p></o:p></p>
<p class="MsoNormal">I have an application that worked previously with composite data, specifically multiblocks of unstructured grids.<o:p></o:p></p>
<p class="MsoNormal">I’ve been attempting to use an unstructured grid in my composite data source and it is read in correctly but<o:p></o:p></p>
<p class="MsoNormal">as soon as I pass it to a vtkCompositeDataGeometryFilter, the output doesn’t contain any cells, as if the filter doesn’ t recognize<o:p></o:p></p>
<p class="MsoNormal">polyhedron cells. The strange thing is, the file reads in as expected in paraview….<o:p></o:p></p>
<p class="MsoNormal">Is there some limitation where vtkCompositeDataGeometryFilter (ie vtkGeometryFilter) doesn’t work with polyhedron cells?<o:p></o:p></p>
