vtkCellArray

Section: Visualization Toolkit Filtering Classes

Usage

vtkCellArray is a supporting object that explicitly represents cell connectivity. The cell array structure is a raw integer list of the form: (n,id1,id2,...,idn, n,id1,id2,...,idn, ...) where n is the number of points in the cell, and id is a zero-offset index into an associated point list.

Advantages of this data structure are its compactness, simplicity, and easy interface to external data. However, it is totally inadequate for random access. This functionality (when necessary) is accomplished by using the vtkCellTypes and vtkCellLinks objects to extend the definition of the data structure.

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

  obj = vtkCellArray

Methods

The class vtkCellArray 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 vtkCellArray class.
