Then it’s passed through a vtkProbeFilter as the input data & the probe filter source connection is set as a vtkImageBlend output. The issue I have is when I try to access the resulting polydata’s Normals via polydata->GetPointData()->GetNormals() it always returns NULL. Somewhere down the line I believe the normals are being removed or ignored. Can someone point me in the right direction?</div><div class=""><br class=""></div><div class="">Regards,</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Seun</div><div class=""><br class=""></div><div class=""><div style="margin: 0px; font-size: 11px; line-height: normal; font-family: Menlo; color: rgb(112, 61, 170);" class=""><br class=""></div></div><div style="margin: 0px; font-size: 11px; line-height: normal; font-family: Menlo;" class=""><br class=""></div><div style="margin: 0px; font-size: 11px; line-height: normal; font-family: Menlo;" class=""><br class=""></div></body></html>
