[vtkusers] Fill contour

[Jothybasu Selvaraj]

Hi David

If I set the representation to surface only the outline is shown. I even
tried it with a vtkPolyDataMapper and the results are same.

Here is the rough pipeline

vtkSmartPointer<vtkPolyData>contour=

            vtkSmartPointer<vtkPolyData>::New();

    contour=this->ContourWidget->GetContourRepresentation()->GetContourRepresentationAsPolyData();



    vtkSmartPointer<vtkContourTriangulator>tc=

            vtkSmartPointer<vtkContourTriangulator>::New();

    tc->SetInputData(contour);

    tc->Update();




    vtkSmartPointer<vtkDataSetMapper> polyMapper =

            vtkSmartPointer<vtkDataSetMapper>::New();

    polyMapper->SetInputData(tc->GetOutput());

    polyMapper->ScalarVisibilityOn();

    polyMapper->Update();



     this->polyActor =

            vtkSmartPointer<vtkActor>::New();

    polyActor->SetMapper(polyMapper);

    polyActor->GetProperty()->SetColor(0,1,0);

    polyActor->GetProperty()->SetRepresentationToWireframe();


    this->ViewRenderer->AddActor(this->polyActor);

    this->ViewRenderer->GetRenderWindow()->Render();

    this->ViewRenderer->ResetCamera();


Thanks


Jothy
