This path consists of a Locale, a terminal node, and an array of internal nodes that are in the path from the Locale to the terminal node. The terminal node may be either a Leaf node or a Group node. A valid SceneGraphPath must uniquely identify a specific instance of the terminal node. For nodes that are not under a SharedGroup, the minimal SceneGraphPath consists of the Locale and the terminal node itself. For nodes that are under a SharedGroup, the minimal SceneGraphPath consists of the Locale, the terminal node, and a list of all Link nodes in the path from the Locale to the terminal node. A SceneGraphPath may optionally contain other interior nodes that are in the path. A SceneGraphPath is verified for correctness and uniqueness when it is sent as an argument to other methods of Java 3D. <p> In the array of internal nodes, the node at index 0 is the node closest to the Locale. The indices increase along the path to the terminal node, with the node at index length-1 being the node closest to the terminal node. The array of nodes does not contain either the Locale (which is not a node) or the terminal node. <p> When a SceneGraphPath is returned from the picking or collision methods of Java 3D, it will also contain the value of the LocalToVworld transform of the terminal node that was in effect at the time the pick or collision occurred. Note that ENABLE_PICK_REPORTING and ENABLE_COLLISION_REPORTING are disabled by default. This means that the picking and collision methods will return the minimal SceneGraphPath by default.<P><P><DL><DT><B>See Also:</B><DD><A
