摘要

A three-dimensional data encoding method includes: generating pieces of encoded data by encoding subspaces obtained by dividing a current space including three-dimensional points (S5181); and generating a bitstream including the pieces of encoded data and pieces of first information (tile_null_flag) each of which corresponds to a corresponding one of the subspaces (S5182). Each of the pieces of first information indicates whether the bitstream includes second information indicating a structure of the corresponding one of the subspaces. For example, the second information may include information indicating the origin coordinates of the corresponding subspace.
