[vtkusers] Reading nrrd files

[Sam Raby]

Hello

I would like to read a nrrd file and be able to scroll through slices. Is
there an example online that can help on how to use vtknrrdreader in order
to do that?

The following is what I have written so far.

Thanks
Sam


vtkSmartPointer<vtkNrrdReader> reader =
vtkSmartPointer<vtkNrrdReader>::New();
reader->SetFileName(argv[1]);

vtkSmartPointer<vtkImageViewer2> imageViewer =
vtkSmartPointer<vtkImageViewer2>::New();
imageViewer->SetInputConnection(reader->GetOutputPort());

vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();

imageViewer->SetupInteractor(renderWindowInteractor);
imageViewer->Render();
imageViewer->GetRenderer()->ResetCamera();
imageViewer->Render();

renderWindowInteractor->Start();
