/**
 * @class   vtkBumpMapRepresentation
 * @brief   Representation for showing data sets with bump mapping effect.
 *
 * This representation display its input mesh using a bump mapping effect.
 * A bump mapping effect is a modification of the normals in order to add
 * embossing on a flat mesh thanks to the lights of the scene.
 *
 * @par Thanks:
 * This class was written by Joachim Pouderoux and Michael Migliore, Kitware 2017
 * This work was supported by the German Climate Computing Center (DKRZ).
