[vtkusers] read and view .vtk file

[Zou Jing]

Dear all

T want to read and view .vtk file ,but there is an error at    actor->SetMapper(Mapper)

said that There is no proper conversion function from vtkSmartPointer<vtkPolyDataMapper> to<vtkImageMapper3D> .

here is my code:

vtkSmartPointer<vtkPolyDataReader> vtkReader = vtkSmartPointer<vtkPolyDataReader>::New();
vtkReader->SetFileName("C:\\Users\\Administrator\\Desktop\\jing\\t.vtk");

//vtkSmartPointer<vtkPolyData> polydata = vtkReader->GetOutput();

vtkSmartPointer<vtkPolyDataMapper> Mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
Mapper->SetInputConnection(vtkReader->GetOutputPort());

vtkSmartPointer<vtkImageActor> actor =
vtkSmartPointer<vtkImageActor>::New();
actor->SetMapper(Mapper);//->SetInputConnection(vtkreader->GetOutputPort());

vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renderWindow);
renderer->AddActor(actor);
renderer->SetBackground(.2, .3, .4);
renderWindow->Render();
renderWindowInteractor->Start();
return 0;
