 * @class   vtkNonOverlappingAMRLevelIdScalars
 * @brief   generate scalars from levels.
 *
 * vtkNonOverlappingAMRLevelIdScalars is a filter that generates scalars using
 * the level number for each level. Note that all datasets within a level get
 * the same scalar. The new scalars array is named \c LevelIdScalars.
