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.
__init__ | ( | ) |
Constructs an empty union.
addComponent | ( | 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.
clearComponents | ( | ) |
Removes all components from the volume.
filterIntersection | ( | const BoundingVolume | volume | ) |
Removes from the union any components that have no intersection with the indicated volume.

const GeometricBoundingVolume getComponent | ( | int | n | ) |

list getComponents | ( | ) |
int getNumComponents | ( | ) |
Returns the number of components in the union.
operator new | ( | int | size | ) |
const GeometricBoundingVolume components[] |
Returns the nth component in the union.
