Abstract
A three-dimensional data encoding method includes: encoding information of a target node included in an N-ary tree structure of three-dimensional points included in three-dimensional data; and generating a bitstream including the information of the target node encoded. In the encoding, the target node is encoded based on reference limitation information indicating a referable neighbor node among neighbor nodes spatially neighboring the target node. In the generating, when the target node is encoded by reference to information of a first neighbor node, the bitstream further including encoding processing information is generated, the encoding processing information indicating a processing method in the encoding; and when the target node is encoded without reference to the information of the first neighbor node, the bitstream is generated without including the encoding processing information in the bitstream.
