Class BoundingLeaf
This allows an application to specify a bounding region in one coordinate system (the local coordinate system of the BoundingLeaf node) other than the local coordinate system of the node that references the bounds. For an example of how this might be used, consider a closed room with a number of track lights. Each light can move independent of the other lights and, as such, needs its own local coordinate system. However, the bounding volume is used by all the lights in the boundary of the room, which doesn't move when the lights move. In this example, the BoundingLeaf node allows the bounding region to be defined in the local coordinate system of the room, rather than in the local coordinate system of a particular light. All lights can then share this single bounding volume.

Method Details
-
setRegion
Sets this BoundingLeaf node's bounding region.- Parameters:
region
- the bounding region of this leaf node- Throws:
CapabilityNotSetException
- if appropriate capability is not set and this object is part of live or compiled scene graph
-
getRegion
Retrieves this BoundingLeaf's bounding region.- Returns:
- the bounding region of this leaf node
