This document defines the JPEG Pleno framework for learning-based point cloud coding. This document is applicable to interactive human visualization, with competitive compression efficiency compared to state of the art point cloud coding solutions in common use, and effective performance for 3D processing and machine-related computer vision tasks, and has the goal of supporting a royalty-free baseline. This document specifies a coded codestream format for storage of point clouds. It provides information on the encoding tools. It also defines extensions to the JPEG Pleno File Format and associated metadata descriptors that are specific to point cloud modalities.
