Abstract: A system comprises an encoder configured to compress attribute information for a dynamic point cloud and/or a decoder configured to decompress compressed attribute information for a dynamic point cloud. The dynamic point cloud may include multiple versions of the point cloud at multiple moments in time Attribute values for the point cloud may be compressed at a reference frame using an intra-prediction process and may be compressed at one or more reference frames using an inter-prediction process that takes advantage of temporal relationships between different frames (e.g. versions) of the dynamic point cloud at the different moments in time.
