vtkDicer

Section: Visualization Toolkit Graphics Classes

Usage

Subclasses of vtkDicer divides the input dataset into separate pieces. These pieces can then be operated on by other filters (e.g., vtkThreshold). One application is to break very large polygonal models into pieces and performing viewing and occlusion culling on the pieces. Multiple pieces can also be streamed through the visualization pipeline.

To use this filter, you must specify the execution mode of the filter; i.e., set the way that the piece size is controlled (do this by setting the DiceMode ivar). The filter does not change the geometry or topology of the input dataset, rather it generates integer numbers that indicate which piece a particular point belongs to (i.e., it modifies the point and cell attribute data). The integer number can be placed into the output scalar data, or the output field data.

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

  obj = vtkDicer
