MITK Tutorial - Step 7: Convert result of region growing into a surface

In this step the result of the previous step is converted into a surface by means of a VTK filter.

• Step7.cpp
  
• Step7.h
  
• Step7main.cpp
  

Step7 inherits from Step6. It enhances the method StartRegionGrowing() by processing the result image.

  if(m_ResultImage.IsNotNull())
  {
    m_ResultNode->SetProperty("volumerendering", mitk::BoolProperty::New(false));

    vtkMarchingCubes* surfaceCreator = vtkMarchingCubes::New();
    surfaceCreator->SetInput(m_ResultImage->GetVtkImageData());
    surfaceCreator->SetValue(0, 1);

    mitk::Surface::Pointer surface = mitk::Surface::New();
    surface->SetVtkPolyData(surfaceCreator->GetOutput());

    mitk::DataNode::Pointer surfaceNode = mitk::DataNode::New();
    surfaceNode->SetData(surface);

    m_DataStorage->Add(surfaceNode);

    mitk::RenderingManager::GetInstance()->RequestUpdateAll();
    std::cout << "8";
    surfaceCreator->Delete();
  }
