 * @class   vtkStructuredPointsReader
 * @brief   read vtk structured points data file
 *
 * vtkStructuredPointsReader is a source object that reads ASCII or binary
 * structured points data files in vtk format (see text for format details).
 * The output of this reader is a single vtkStructuredPoints data object.
 * The superclass of this class, vtkDataReader, provides many methods for
 * controlling the reading of the data file, see vtkDataReader for more
 * information.
 * @warning
 * Binary files written on one system may not be readable on other systems.
