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.
-
Warning:
-
The number of pieces generated may not equal the specified number of pieces. Use the method GetNumberOfActualPieces() after filter execution to get the actual number of pieces generated.

Set/Get the flag which controls whether to generate point scalar data or point field data. If this flag is off, scalar data is generated. Otherwise, field data is generated. Note that the generated the data are integer numbers indicating which piece a particular point belongs to. |

Set/Get the number of pieces the object is to be separated into. (This ivar has effect only when the DiceMode is set to SetDiceModeToSpecifiedNumber()). Note that the ivar NumberOfPieces is a target - depending on the particulars of the data, more or less number of pieces than the target value may be created. |
