+/**
+ * The OrientedShape3D leaf node is a Shape3D node that is oriented
+ * along a specified axis or about a specified point.  It defines an
+ * alignment mode and a rotation point or axis.  This will cause
+ * the local +<i>z</i> axis of the object to point at the viewer's eye
+ * position. This is done regardless of the transforms above this
+ * OrientedShape3D node in the scene graph.  It optionally defines a
+ * scale value along with a constant scale enable flag that causes
+ * this node to be scale invariant, subject only to its scale.
+ *
+ * <p>
+ * OrientedShape3D is similar in functionality to the Billboard
+ * behavior, but OrientedShape3D nodes will orient themselves
+ * correctly for each view, and they can be used within a SharedGroup.
+ *
+ * <p>
+ * If the alignment mode is ROTATE_ABOUT_AXIS, then the rotation will be
+ * around the specified axis.  If the alignment mode is
+ * ROTATE_ABOUT_POINT, then the rotation will be about the specified
+ * point, with an additional rotation to align the +<i>y</i> axis of the
+ * TransformGroup with the +<i>y</i> axis in the View.
+ *
+ * <p>
+ * If the constant scale enable flag is set, the object will be drawn
+ * the same size in absolute screen coordinates (meters), regardless
+ * of the following: any transforms above this OrientedShape3D node in
+ * the scene graph, the view scale, the window scale, or the effects
+ * of perspective correction.  This is done by scaling the geometry
+ * about the local origin of this node, such that 1 unit in local
+ * coordinates is equal to the number of meters specified by this
+ * node's scale value.  If the constant scale enable flag is set to
+ * false, then the scale is not used.  The default scale is 1.0
+ * meters.
+ *
+ * <p>
+ * OrientedShape3D nodes are ideal for drawing screen-aligned text or
+ * for drawing roughly-symmetrical objects.  A typical use might
+ * consist of a quadrilateral that contains a texture of a tree.
+ *
+ * <p>
+ * Note that in a multiple View system, picking and interestion test
+ * is done with the primary View only.
+ *
+ * @see Billboard
+ *
+ * @since Java 3D 1.2
