1. A three-dimensional data encoding method comprising:
generating a layered structure including one or more layers by hierarchically arranging three-dimensional points each having an attribute information item;
encoding the attribute information item of each of the three-dimensional points using the layered structure; and
generating a first bitstream including the attribute information item encoded and an identification information item indicating whether the three-dimensional points are re-ordered in Morton order.
