1. A three-dimensional data encoding method of encoding three-dimensional data, the three-dimensional data including geometry information and attribute information corresponding to the geometry information, the three-dimensional data encoding method comprising:
encoding the geometry information; and
encoding the attribute information with reference to the geometry information corresponding to the attribute information,
wherein units include (i) a unit of the encoded geometry information, (ii) a unit of the encoded attribute information, (iii) a unit of a geometry parameter set, and (iv) a unit of an attribute parameter set,
each of the units includes information indicating a type of data included in the unit,
the geometry parameter set includes control information for the encoded geometry information, and the attribute parameter set includes control information for the encoded attribute information, and
a bitstream includes identification information indicating the unit of the encoded geometry information corresponding to the unit of the encoded attribute information.
