1. A method of decoding comprising:
receiving an entropy coded bitstream comprising compressed video data including point cloud occupancy codes;
generating one or more dequantized dimensions of a boundary box of a point cloud; and
adaptively selecting a predictor between an attribute-based predictor and a geometry-based predictor, and building an octree structure by subdividing the boundary box of the point cloud according to the one or more dequantized dimensions of the boundary box including the occupancy codes of the point cloud by using the selected predictor.
