Claim 17:
18. A three-dimensional data decoding device, comprising:
a processor; and
memory,
wherein using the memory, the processor:
obtains a bitstream; and
decodes information of a current node included in an N-ary tree structure of three-dimensional points included in three-dimensional data, where N is an integer greater than or equal to 2,
wherein in the decoding, first information is decoded from the bitstream,
wherein in the decoding, a range for one or more available nodes is determined based on the first information, the one or more available nodes being referable during the decoding,
wherein in the decoding, the current node is decoded with reference to a neighboring node corresponding to one of the one or more available nodes within the range, and
wherein in the decoding, whether the neighboring node includes a three-dimensional point is determined.
