Claim 2:
3. The three-dimensional data encoding method according to claim 2, further comprising:
encoding attribute information of each of the three-dimensional points based on one of (i) a first attribute information encoding method of performing entropy encoding after performing transform processing of transforming a value of the attribute information using a predetermined method and (ii) a second attribute information encoding method of performing entropy encoding without performing the transform processing,
wherein in the encoding of the attribute information:
when the total number of the three-dimensional points is greater than or equal to a predetermined number, the encoding is performed based on the first attribute information encoding method; and
when the total number of the three-dimensional points is less than the predetermined number, the encoding is performed based on the second attribute information encoding method, and

in the generating of the bitstream, the bitstream including an attribute information flag indicating whether the encoding was performed based on the first attribute information encoding method or the second attribute information encoding method is generated.
