Claim 12:
13. A three-dimensional data decoding device, comprising:
a processor; and
memory, wherein
using the memory, the processor:
obtains 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:
generates the layered structure using at item of information included in the bitstream and used for the selecting; and
decodes 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:
decodes the attribute information for the plurality of three-dimensional points in a second order.
