Claim 2:
3. The three-dimensional data encoding method according to claim 2, wherein
a first bit number is different from a second bit number, the first bit number being a number of bits shifted by each of the left bit shift and the right bit shift performed in the first encoding scheme, the second bit number being a number of bits shifted by each of the left bit shift and the right bit shift performed in the second encoding scheme, and
in the first encoding scheme, the performing of the transformation includes:
(i) applying the first table to the first scale value to determine the first quantization parameter; or
(ii) applying the first table to the first quantization parameter to determine the first scale value, and

in the second encoding scheme, the performing of the transformation includes:
(i) performing bit shift on the first scale value by a number of bits corresponding to a difference between the first bit number and the second bit number to obtain a shifted first scale value, and applying the first table to the shifted first scale value to determine the first quantization parameter; or
(ii) applying the first table to the first quantization parameter to determine a third scale value, and performing bit shift on the third scale value by a number of bits corresponding to the difference between the first bit number and the second bit number to generate the first scale value.
