Abstract
A three-dimensional data encoding method includes: appending, to a bitstream, first information indicating whether a leaf to be included in an N-ary tree structure of three-dimensional points included in three-dimensional data is to include a single three-dimensional point or two or more three-dimensional points, where N is an integer greater than or equal to 2; when the first information indicates that the leaf is to include a single three-dimensional point, generating an N-ary tree structure in which a leaf includes a single three-dimensional point, and encoding the N-ary tree structure; and when the first information indicates that the leaf is to include two or more three-dimensional points, generating an N-ary tree structure in which a leaf includes two or more three-dimensional points, and encoding the N-ary tree structure.
