Perform calculations (mostly intersection calculations) on regions of a 3D binary spatial partitioning.
<p>
Given an axis aligned binary spatial partitioning described by a <a class="el" href="a00217.html" title="This class represents an axis-aligned Binary Spatial Partitioning of a 3D space.">vtkBSPCuts</a> object, perform intersection queries on various geometric entities with regions of the spatial partitioning.<p>
