Visualization of digital elevation models (DEM) is often more intuitive by
simulating a lighting source and generating the corresponding shadows. This
principle is called hill shading.
Using :doxygen:`HillShadingFilter` and the DEM image generated
using the :doxygen:`DEMToImageGenerator`, you can easily obtain a representation
of the DEM. Better yet, using the :doxygen-itk:`ScalarToRGBColormapImageFilter`
combined with the ``ReliefColormapFunctor`` you can easily generate the
classic elevation maps.
This example will focus on the shading itself.
