1. A three-dimensional data encoding method, comprising:
(i) in a case where a layered structure comprising a plurality of layers is generated by selecting at least one three-dimensional point assigned to one of the plurality of layers from a plurality of three-dimensional points:
encoding attribute information for the three-dimensional points in a first order, the first order being an order determined based on the layered structure; and
generating a bitstream including an item of information used for the selecting; and
(ii) in a case where the layered structure is not generated:
encoding attribute information for the plurality of three-dimensional points in a second order; and
generating a bitstream not including the item of information used for the selecting,
wherein the attribute information includes information related to a vector.
