Classification: CPC H  G | IPC H

Claim 3:
4. A method of processing point cloud data in a reception device, the method comprising:
receiving a bitstream including the point cloud data, the point cloud data including geometry information and attribute information, wherein the geometry information represents positions of points of the point cloud data and the attribute information represents attributes of the points of the point cloud data; and
decoding the point cloud data,
wherein the decoding the point cloud data includes decoding the geometry information and decoding the attribute information,
wherein the decoding the point cloud data includes decoding the geometry information and decoding the attribute information,
wherein the decoding the attribute information includes generating at least one LOD (Level of Detail),
wherein the generating at least one LOD includes sampling at least one point in at least one node of an octree,
wherein the at least one point is a closest point from a center of the at least one node,
wherein the bitstream further includes LOD generation-related information, the LOD generation-related information including information that represents a method for the sampling.
