1. A three-dimensional data encoding method comprising:
assigning a three-dimensional point to one of layers, based on geometry information of the three-dimensional point;
generating (i) first information indicating a first search range for same layer reference and (ii) second information indicating a second search range not for the same layer reference, the same layer reference being referencing other three-dimensional points included in a same layer to which a current three-dimensional point to be encoded belongs; and
encoding attribute information of the current three-dimensional point to generate a bitstream, by or without the same layer reference,
wherein the bitstream includes the first information and the second information.
