Detailed Description
This special bounding volume is the union of all of its constituent bounding volumes.
A point is defined to be within a UnionBoundingVolume if it is within any one or more of its component bounding volumes.
Definition at line 29 of file unionBoundingVolume.h.
Constructor & Destructor Documentation
◆ UnionBoundingVolume()
|
inline |
Constructs an empty union.
Definition at line 18 of file unionBoundingVolume.I.
Member Function Documentation
◆ add_component()
| void UnionBoundingVolume::add_component | ( | const GeometricBoundingVolume * | component | ) |
Adds a new component to the volume.
This does not necessarily increase the total number of components by one, and you may or may not be able to find this component in the volume by a subsequent call to get_component(); certain optimizations may prevent the component from being added, or have other unexpected effects on the total set of components.
Definition at line 130 of file unionBoundingVolume.cxx.
References BoundingVolume::is_empty(), and BoundingVolume::is_infinite().
◆ clear_components()
| void UnionBoundingVolume::clear_components | ( | ) |
Removes all components from the volume.
Definition at line 117 of file unionBoundingVolume.cxx.
◆ filter_intersection()
| void UnionBoundingVolume::filter_intersection | ( | const BoundingVolume * | volume | ) |
Removes from the union any components that have no intersection with the indicated volume.
Definition at line 170 of file unionBoundingVolume.cxx.
