PolyData.obbTree#
- property PolyData.obbTree: vtkOBBTree[source]#
Return the obbTree of the polydata.
An obbTree is an object to generate oriented bounding box (OBB) trees. An oriented bounding box is a bounding box that does not necessarily line up along coordinate axes. The OBB tree is a hierarchical tree structure of such boxes, where deeper levels of OBB confine smaller regions of space.
Warning
This property is expensive to compute and is therefore cached. If the mesh’s geometry is modified, the obb tree will no longer be valid.
Deprecated since version 0.49: This property is primarily for internal use only, and the vtkOBBTree locator does not reliably find intersections in some cases.
