Claims16
A method for transmitting point cloud data, the method comprising:
- encoding geometry data of point cloud data, wherein the encoding the geometry data includes:
- predictive geometry encoding the geometry data based on a predictive tree,
- wherein points of the geometry data are sorted based on a sorting type,
- wherein the sorting type includes at least one of an azimuth angle order or a radial distance order, and
- wherein the points are sorted by rounding the at least one of an azimuth or a radius;
- encoding attribute data of point cloud data;
- and
- transmitting a bitstream including the geometry data and the attribute data of the point cloud data.
