Claim 12:
13. A transmission device for processing point cloud data, the transmission device comprising:
an encoder configured to encode 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,
wherein the encoder includes a first encoder configured to encode the geometry information and a second encoder configured to encode the attribute information,
wherein the second encoder 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, and
wherein the at least one point is a closest point from a center of the at least one node; and
a transmitter configured to transmit a bitstream including the encoded point cloud data,
wherein the bitstream further includes LOD generation-related information, the LOD generation-related information including information that represents a method for the sampling.
