 * @class   vtkImageDataToPointSet
 * @brief   Converts a vtkImageData to a vtkPointSet
 *
 *
 * vtkImageDataToPointSet takes a vtkImageData as an image and outputs an
 * equivalent vtkStructuredGrid (which is a subclass of vtkPointSet).
 *
 * @par Thanks:
 * This class was developed by Kenneth Moreland (kmorel@sandia.gov) from
 * Sandia National Laboratories.
