          javax.media.j3d.Node

    public class BoundingLeaf

extends Leaf

The BoundingLeaf node defines a bounding region object that can be referenced by other nodes to define a region of influence (Fog and Light nodes), an application region (Background, Clip, and Soundscape nodes), or a scheduling region (Sound and Behavior nodes). The bounding region is defined in the local coordinate system of the BoundingLeaf node. A reference to a BoundingLeaf node can be used in place of a locally defined bounds object for any of the aforementioned regions.

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.

Constructor Detail

### BoundingLeaf

    public BoundingLeaf()

  Constructs a BoundingLeaf node with a null (empty) bounding region.

### BoundingLeaf

    public BoundingLeaf(Bounds region)

  Constructs a BoundingLeaf node with the specified bounding region.

  Parameters:
    `region` - the bounding region of this leaf node

Method Detail

### setRegion

    public void setRegion(Bounds region)

  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

    public Bounds getRegion()

  Retrieves this BoundingLeaf's bounding region.

  Returns:
    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

### cloneNode

    public Node cloneNode(boolean forceDuplicate)

  Used to create a new instance of the node. This routine is called by `cloneTree` to duplicate the current node.

  Overrides:
    `cloneNode` in class `Node`
  Parameters:
    `forceDuplicate` - when set to `true`, causes the `duplicateOnCloneTree` flag to be ignored. When `false`, the value of each node's `duplicateOnCloneTree` variable determines whether NodeComponent data is duplicated or copied.
