This paper presents the MPEG-4 Animation Framework eXtension (AFX) standard, ISO/IEC 14496–16. Initiated by the MPEG Synthetic/Natural Hybrid Coding group in 2000, MPEG-4 AFX proposes an advanced framework for interactive multimedia applications using both natural and synthetic objects. Following this model, new synthetic objects have been specified,(More)
SSs (Subdivision Surfaces) are a powerful modelling paradigm for truly hierarchical (instead of merely progressive) 3D surface (as opposed to mesh) coding. Two SS-based tools of MPEG-4’s Animation Framework eXtension allow to derive a piecewise smooth surface from an initial control mesh: if the subdivision process is run in its predefined form, the initial(More)
