Claim 13:
14. A device for encoding three-dimensional data, comprising:
a processor; and
memory,
wherein using the memory, the processor
obtains data with respect to three-dimensional points;
generates an N-ary tree structure representing the three-dimensional points, where N is an integer greater than or equal to 2;
determines referenceable nodes for a current node included in the N-ary tree structure;
generates first information with respect to the determined referenceable nodes; and
encodes the current node referring to neighboring nodes, each of the neighboring nodes being included in the determined referenceable nodes and neighboring the current node in one of a first axis direction, a second axis direction, and a third axis direction, and

wherein when the first information indicates a first value, only neighboring nodes located inside a parent node of the current node are determined as the referenceable nodes.
