      imageViewer->GetRenderWindow()->SetSize( 500, 500 );
      imageViewer->GetRenderer()->ResetCamera();

      // Set up an interactor that does not respond to mouse events
      vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
        vtkSmartPointer<vtkRenderWindowInteractor>::New();

### Download and Build ImageSinusoidSource

Click here to download ImageSinusoidSource and its CMakeLists.txt file. Once the tarball ImageSinusoidSource.tar has been downloaded and extracted,

    cd ImageSinusoidSource/build

If VTK is installed:

    cmake ..

If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:

    cmake -DVTK_DIR:PATH=/home/me/vtk_build ..

Build the project:

    make

and run it:

    ./ImageSinusoidSource
