Disclosed herein is a method for transmitting point cloud data, including encoding the point cloud data, and transmitting a bitstream containing the point cloud data.
Claims10
A method for receiving point cloud data, the method comprising:
- receiving a bitstream including point cloud data,
- the point cloud data including geometry data and attribute data;
- decoding the geometry data;
- and
- decoding the attribute data,
- wherein the geometry data include a tree,
- wherein LOD(Level of Detail)s are generated based on the geometry data,
- wherein points of the geometry data in the LODs are sorted based on a Morton code,
- wherein a point having a lowest point index included in a LOD of which a detail level is an even is sampled and a point having a greatest point index included in a LOD of which a detail level is an odd is sampled.
