Claim 3:
4. The three-dimensional data encoding method according to claim 1, further comprising:
performing transformation, the transformation being one of (i) transforming a second quantization parameter to a fourth scale value and (ii) transforming the fourth scale value to the second quantization parameter, based on a second table indicating a correspondence between a plurality of values of the second quantization parameter and a plurality of values of the fourth scale value, the second table being shared between the first encoding scheme and the second encoding scheme; and
performing encoding including a second quantization process to generate encoded geometry information, the second quantization process being a process of dividing, by the fourth scale value, each of second coefficient values based on items of geometry information of the three-dimensional points, wherein
the bitstream further includes the encoded geometry information and the second quantization parameter.
