THREE-DIMENSIONAL DATA ENCODING METHOD, THREE-DIMENSIONAL DATA DECODING METHOD, THREE-DIMENSIONAL DATA ENCODING DEVICE, AND THREE-DIMENSIONAL DATA DECODING DEVICE

原文（中国語）

A three-dimensional data encoding method includes: obtaining second attribute information obtained by transforming first attribute information of a three-dimensional point in at least one frame among frames, the frames constituting a sequence; and encoding the second attribute information to generate a bitstream. The transforming is different from quantization, and the bitstream further includes: at least one first parameter provided for the sequence for the transforming; and at least one second parameter provided for each of the at least one frame for the transforming.
