Abstract

A method for encoding, in a bitstream, point attributes associated to a point of a point cloud, includes: determining, for a point P to be encoded to the bitstream, a predictor list of k predictor points of the point cloud including k points of the point cloud nearest to the point P to be encoded, wherein the k points are selected according to their relative position to each other; and encoding the point attributes associated to the point P to be encoded by predictive encoding based on attributes of the predictor points of the predictor list.
