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.
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 +y axis of the TransformGroup with the +y axis in the View.
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.
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.
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
