/**
* @class vtkOBBDicer
* @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.
