1. A point cloud decoding method, applied for a decoder, comprising:
obtaining Morton codes for a point cloud according to geometry information of the point cloud after geometry decoding is completed and the geometry information is reconstructed;
determining the point cloud as an input point cloud of an iteration;
shifting Morton codes for an input point cloud of an i-th iteration right by K bits according to a number of points in the input point cloud of the i-th iteration, K being a positive integer;
selecting a point from points with a same value of Morton codes after right shifted by K bits;
forming an i-th level of detail (LOD) layer with the point selected; and
decoding color information according to the LOD layer.
