Abstract
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; and generating a bitstream including the pieces of encoded data and pieces of first information each of which corresponds to a corresponding one of the subspaces. Each of the pieces of first information indicates whether the bitstream includes second information indicating a structure of the corresponding one of the subspaces.

A three-dimensional data encoding method, comprising:
- generating pieces of encoded data by encoding subspaces obtained by dividing a current space including three-dimensional points;
- and
- generating a bitstream including the pieces of encoded data and pieces of first information each of which corresponds to a corresponding one of the subspaces,
- wherein each of the pieces of first information indicates whether the corresponding one of the subspaces includes data.
A three-dimensional data decoding method, comprising:
- obtaining from a bitstream pieces of first information each of which corresponds to a corresponding one of subspaces obtained by dividing a current space including three-dimensional points;
- and
- decoding pieces of encoded data using the pieces of first information, the pieces of encoded data being included in the bitstream and generated by encoding the subspaces,
- wherein each of the pieces of first information indicates whether the corresponding one of the subspaces includes data.
A three-dimensional data encoding device, comprising:
- a processor;
- and
- memory,
- wherein using the memory, the processor:
