1. A three-dimensional data encoding device comprising:
a processor; and
memory, wherein
using the memory, the processor:
obtains 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
encodes the second attribute information to generate a bitstream, wherein
the transforming is different from quantization, and
the bitstream further includes:
at least one first parameter provided for the sequence for the transforming;
at least one second parameter provided for each of the at least one frame for the transforming; and
second information indicating a format type of point cloud data including the second attribute information.
