[vtkusers] Reading nrrd files

[Moreland, Kenneth]

Have you tried calling SetDataVOI on the vtkNrrdReader? I don't think it works on ASCII files, but it should work on raw binary encoding.

Subject: [EXTERNAL] [vtkusers] Reading nrrd files

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();
