Classification: CPC H  G | IPC H

Claim 1:
2. The three-dimensional data encoding method according to claim 1, wherein
the encoding including the first quantization process includes:
performing left bit shift on each of the items of attribute information to generate items of shifted attribute information; and
performing, on the items of shifted attribute information, a transformation process using items of geometry information of the three-dimensional points to generate the first coefficient values, wherein

the first scale value is a value generated by multiplying a second scale value for quantization by a coefficient corresponding to the left bit shift, and
the quantization and right bit shift are performed by dividing each of the first coefficient values by the first scale value, the right bit shift shifting a same number of bits as a number of bits shifted by the left bit shift.
