vtkDataSetToDataObjectFilter

Section: Visualization Toolkit Graphics Classes

# Usage

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.

To create an instance of class vtkDataSetToDataObjectFilter, simply invoke its constructor as follows

      obj = vtkDataSetToDataObjectFilter
