Claim 7:
8. A three-dimensional data decoding method, comprising:
obtaining a bitstream including a plurality of three-dimensional points that have been encoded; and
(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 the plurality of three-dimensional points:
generating the layered structure using an item of information included in the bitstream and used for the selecting; and
decoding attribute information for the plurality of three-dimensional points in a first order, the first order being an order determined based on the layered structure; and

(ii) in a case where the layered structure is not generated:
decoding the attribute information for the plurality of three-dimensional points in a second order.
