Claim 10:
11. A three-dimensional data encoding device, comprising:
a processor; and
memory,
wherein using the memory, the processor:
obtaining orthogonal geometry information indicating each position of a three-dimensional point cloud in orthogonal coordinates;
obtaining a plurality of parameters including first horizontal angle information and first vertical angle information corresponding to the three-dimensional point cloud;
converting, using at least one of the plurality of parameters, the orthogonal geometry information into polar geometry information indicating each position of the three-dimensional point cloud in polar coordinates;
encoding the polar geometry information; and
generating a bitstream including the polar geometry information encoded, and

wherein the converted polar geometry information includes second horizontal angle information, second vertical angle information, and distance information from a reference point corresponding to each position of the three-dimensional point cloud.
