1. A three-dimensional data encoding method, comprising:
encoding a parameter; and
encoding information of a current node included in an N-ary tree structure of three-dimensional points, where N is an integer greater than or equal to 2,
wherein in the encoding of the information of the current node, when the parameter indicates first information, setting invalid bits from eight bits corresponding to the current node.
