// .NAME vtkDataSetToDataObjectFilter - map dataset into data object (i.e., a field)
// .SECTION Description
// 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.
