Abstract
Overview - ISO/IEC 14496-16:2011/Amd 2:2014 (Multi‑resolution 3D mesh compression)
ISO/IEC 14496-16:2011/Amd 2:2014 is an amendment to Part 16 (Animation Framework eXtension, AFX) that defines Multi‑Resolution 3D Mesh Coding (MR3DMC). The amendment specifies a progressive, coarse‑to‑fine bitstream format for compressing manifold triangular 3D meshes (IndexedFaceSet), supporting single or multiple attributes per vertex or per triangle. The MR3DMC stream is encapsulated in an AFX stream (AFX object code 0x0C) and is intended to improve rate‑distortion performance while enabling scalable delivery of 3D geometry and attributes.
