[vtkusers] The vtkFillHolesFilter doen't work.

[Jochen K.]

Hi Charles,


you may have forgotten to call Update on the FillHolesFilter. This is part
of a common pipeline for filling holes:

//...
vtkSmartPointer<vtkFillHolesFilter> fillHolesFilter =
    vtkSmartPointer<vtkFillHolesFilter>::New();
#if VTK_MAJOR_VERSION <= 5
  fillHolesFilter->SetInputConnection(input->GetProducerPort());
#else
  fillHolesFilter->SetInputData(input);
#endif
 
  fillHolesFilter->Update();
 
  vtkSmartPointer<vtkPolyDataMapper> filledMapper =
    vtkSmartPointer<vtkPolyDataMapper>::New();
  filledMapper->SetInputConnection(fillHolesFilter->GetOutputPort());
 
  vtkSmartPointer<vtkActor> filledActor =
    vtkSmartPointer<vtkActor>::New();
  filledActor->SetMapper(filledMapper);
//...



You also might want to have a look at a full example:
