FIELD: data processing.
SUBSTANCE: invention relates to the field of data processing. The effect is achieved in that the method includes receiving an entropy-coded bitstream containing compressed video data, including point cloud occupancy codes, generating one or more dequantized point cloud boundary block sizes, based on determining that the compressed video data was predicted using attribute-based predictor, determining that the decoding predictor is an attribute-based predictor based on determining that the compressed video data was predicted using the geometry-based predictor, determining that the decoding predictor is a geometry-based predictor, and constructing an octree structure using the determined predictor.
EFFECT: reducing the amount of data required to represent a point cloud representing a three-dimensional (3D) shape.
