vtkDataObject

Section: Visualization Toolkit Filtering Classes

Usage

vtkDataObject is an general representation of visualization data. It serves to encapsulate instance variables and methods for visualization network execution, as well as representing data consisting of a field (i.e., just an unstructured pile of data). This is to be compared with a vtkDataSet, which is data with geometric and/or topological structure.

vtkDataObjects are used to represent arbitrary repositories of data via the vtkFieldData instance variable. These data must be eventually mapped into a concrete subclass of vtkDataSet before they can actually be displayed.

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

  obj = vtkDataObject

Methods

The class vtkDataObject has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, obj is an instance of the vtkDataObject class.
