* @brief divide dataset into spatially aggregated pieces
|
||
|
|
*
|
||
|
|
* vtkOBBDicer separates the cells of a dataset into spatially
|
||
|
|
* aggregated pieces using a Oriented Bounding Box (OBB). 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.
|
||
|
|
*
|
||
|
|
* Refer to the superclass documentation (vtkDicer) for more information.
