Detailed Description

Perform calculations (mostly intersection calculations) on regions of a 3D binary spatial partitioning.

Given an axis aligned binary spatial partitioning described by a vtkBSPCuts object, perform intersection queries on various geometric entities with regions of the spatial partitioning.

GetComputeIntersectionsUsingDataBounds()

virtual int vtkBSPIntersections::GetComputeIntersectionsUsingDataBounds ( )

virtual

When computing the intersection of k-d tree regions with other objects, we use the spatial bounds of the region.

To use the tighter bound of the bounding box of the data within the region, set this variable ON. (Specifying data bounds in the vtkBSPCuts object is optional. If data bounds were not specified, this option has no meaning.)
