ITK in the module ITKVtkGlue provides a simple viewer for 2D and 3D ITK images using VTK.

Read more about it and see examples in this ITK discourse post: [Display 3D image using ITK and VTK](https://discourse.itk.org/t/display-3d-image-using-itk-and-vtk/897/10)

See an example here: [https://github.com/InsightSoftwareConsortium/ITK/blob/master/Modules/Bridge/VtkGlue/test/runViewImage.cxx](https://github.com/InsightSoftwareConsortium/ITK/blob/master/Modules/Bridge/VtkGlue/test/runViewImage.cxx)

and the MWE would be:

```auto
#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkViewImage.h"
int main(int argc, char *argv[])
{
  using PixelType = float;
  constexpr unsigned int Dimension = 3;
  using ImageType = itk::Image<PixelType, Dimension>;
  using ReaderType = itk::ImageFileReader<ImageType>;
  auto reader = ReaderType::New();
  reader->SetFileName("MR-head.nrrd");
  reader->Update();
  itk::ViewImage<ImageType>::View(reader->GetOutput());
}

```

Hope it helps
