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.

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter. Reimplemented in vtkOBBDicer. |
|
Use the following method after the filter has updated to determine the actual number of pieces the data was separated into. |
|
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter. Reimplemented in vtkOBBDicer. |
|
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter. Reimplemented in vtkOBBDicer. |
|
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkSource. Reimplemented in vtkOBBDicer. |
|
Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToDataSetFilter. Reimplemented in vtkOBBDicer. |
|
Specify the method to determine how many pieces the data should be broken into. By default, the number of points per piece is used. |
|
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. |
|
Control piece size based on a memory limit. (This ivar has effect only when the DiceMode is set to SetDiceModeToMemoryLimit()). The memory limit should be set in kilobytes. |
|
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. |
|
Control piece size based on the maximum number of points per piece. (This ivar has effect only when the DiceMode is set to SetDiceModeToNumberOfPoints().) |
