1. A three-dimensional data storage method, comprising:
acquiring one or more units in which an encoded information generated by encoding point cloud data is stored; and
storing the one or more units into a file, wherein
the file indicates an encoding method used in the encoding of the point cloud data out of a plurality of encoding methods including a first encoding method and a second encoding method,
the file is in conformity with ISO Based Media File Format (ISOBMFF),
when the data point cloud data is encoded by the first encoding method, the generated encoded information is stored in a first unit having a first format,
when the data point cloud data is encoded by the second encoding method, the generated encoded information is stored in a second unit having a second format different from the first format, and
each of the first unit and the second unit includes a header and a payload, the payload including encoded data or metadata, the header including information indicating a type of data included in the payload.
