 * @class   vtkDataSetToDataObjectFilter
 * @brief   map dataset into data object (i.e., a field)
 *
 * vtkDataSetToDataObjectFilter is an class that transforms a dataset into
 * data object (i.e., a field). The field will have labeled data arrays
 * corresponding to the topology, geometry, field data, and point and cell
 * attribute data.
 *
 * You can control what portions of the dataset are converted into the
 * output data object's field data. The instance variables Geometry,
 * Topology, FieldData, PointData, and CellData are flags that control
 * whether the dataset's geometry (e.g., points, spacing, origin);
 * topology (e.g., cell connectivity, dimensions); the field data
 * associated with the dataset's superclass data object; the dataset's
 * point data attributes; and the dataset's cell data attributes. (Note:
 * the data attributes include scalars, vectors, tensors, normals, texture
 * coordinates, and field data.)
 *
 * The names used to create the field data are as follows. For vtkPolyData,
 * "Points", "Verts", "Lines", "Polys", and "Strips". For vtkUnstructuredGrid,
 * "Cells" and "CellTypes". For vtkStructuredPoints, "Dimensions", "Spacing",
 * and "Origin". For vtkStructuredGrid, "Points" and "Dimensions". For
 * vtkRectilinearGrid, "XCoordinates", "YCoordinates", and "ZCoordinates".
 * for point attribute data, "PointScalars", "PointVectors", etc. For cell
 * attribute data, "CellScalars", "CellVectors", etc. Field data arrays retain
 * their original name.
