1. A method for point cloud coding, comprising:
determining a plurality of original points associated with a voxel of a plurality of voxels of a point cloud, the plurality of original points being quantized to a predefined reconstructed position of at least one predefined reconstructed position in the voxel, each of the voxels including the same at least one predefined reconstructed position;
determining, by a processor, an attribute value of the predefined reconstructed position based on attribute information of the plurality of original points; and
encoding the point cloud based on the determined attribute value of the predefined reconstructed position.
