Claim 6:
7. A reception device for processing point cloud data, the reception device comprising:
a receiver configured to receive 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
a decoder configured to decode the point cloud data,
wherein the decoder includes a first decoder for decoding the geometry information and a second decoder for decoding the attribute information,
wherein the second decoder includes an LOD (Level of Detail) generator configured to generate at least one LOD,
wherein the LOD generator performs 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, and
wherein the bitstream further includes LOD generation-related information, the LOD generation-related information including information that represents a method for the sampling.
