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. <P> 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.<P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/BoundingLeaf.html#ALLOW_REGION_READ">ALLOW_REGION_READ</A></B></CODE><BR> Specifies that this BoundingLeaf node allows read access to its bounding region object.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static int</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/BoundingLeaf.html#ALLOW_REGION_WRITE">ALLOW_REGION_WRITE</A></B></CODE><BR> Specifies that this BoundingLeaf node allows write access to its bounding region object.</TD></TR></TABLE> <A NAME="fields_inherited_from_class_javax.media.j3d.Node"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class javax.media.j3d.<A HREF="../../../javax/media/j3d/Node.html">Node</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../javax/media/j3d/Node.html#ALLOW_AUTO_COMPUTE_BOUNDS_READ">ALLOW_AUTO_COMPUTE_BOUNDS_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_AUTO_COMPUTE_BOUNDS_WRITE">ALLOW_AUTO_COMPUTE_BOUNDS_WRITE</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_BOUNDS_READ">ALLOW_BOUNDS_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_BOUNDS_WRITE">ALLOW_BOUNDS_WRITE</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_COLLIDABLE_READ">ALLOW_COLLIDABLE_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_COLLIDABLE_WRITE">ALLOW_COLLIDABLE_WRITE</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_LOCAL_TO_VWORLD_READ">ALLOW_LOCAL_TO_VWORLD_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_PICKABLE_READ">ALLOW_PICKABLE_READ</A>, <A HREF="../../../javax/media/j3d/Node.html#ALLOW_PICKABLE_WRITE">ALLOW_PICKABLE_WRITE</A>, <A HREF="../../../javax/media/j3d/Node.html#ENABLE_COLLISION_REPORTING">ENABLE_COLLISION_REPORTING</A>, <A HREF="../../../javax/media/j3d/Node.html#ENABLE_PICK_REPORTING">ENABLE_PICK_REPORTING</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../javax/media/j3d/BoundingLeaf.html#BoundingLeaf()">BoundingLeaf</A></B>()</CODE><BR> Constructs a BoundingLeaf node with a null (empty) bounding region.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../javax/media/j3d/BoundingLeaf.html#BoundingLeaf(javax.media.j3d.Bounds)">BoundingLeaf</A></B>(<A HREF="../../../javax/media/j3d/Bounds.html">Bounds</A> region)</CODE><BR> Constructs a BoundingLeaf node with the specified bounding region.</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../javax/media/j3d/Node.html">Node</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/BoundingLeaf.html#cloneNode(boolean)">cloneNode</A></B>(boolean forceDuplicate)</CODE><BR> Used to create a new instance of the node.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../javax/media/j3d/Bounds.html">Bounds</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/BoundingLeaf.html#getRegion()">getRegion</A></B>()</CODE><BR> Retrieves this BoundingLeaf's bounding region.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/j3d/BoundingLeaf.html#setRegion(javax.media.j3d.Bounds)">setRegion</A></B>(<A HREF="../../../javax/media/j3d/Bounds.html">Bounds</A> region)</CODE><BR> Sets this BoundingLeaf node's bounding region.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_javax.media.j3d.Node"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor">⌨️ 快捷键说明
