// .NAME vtkOBBDicer - divide dataset into spatially aggregated pieces
|
|
// .SECTION Description
|
|
// 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.
