<div>Hi guys,</div>
<div> </div>
<div>I am trying to convert the output of delaunay3D which belong to Unstructured Grid to Polydata. Someone said we can use vtkGeometryFilter to do it. When I try it, I get an error below.</div>
<div> </div>
<div>cannot convert parameter 1 from 'vtkUnstructuredGrid *' to 'vtkDataObject *'</div>
<div> </div>
<div>My coding is:</div>
<div>vtkGeometryFilter *extract = vtkGeometryFilter::New(); <br>extract->SetInput(delaunay3D->GetOutput());</div>
<div> </div>
<div>Thanks,</div>
