METHOD AND APPARATUS FOR ENCODING/DECODING GRAPHIC DATA

摘要

A graphic data encoding method and apparatus generating a bitstream by encoding a header having at least one piece of first information determined in consideration of a predetermined graphic profile from among multiple pieces of encodable first information; and encoding a payload having at least one piece of second information determined in consideration of the predetermined graphic profile from among multiple pieces of encodable second information. A graphic data decoding method and apparatus decode the generated bitstream. Irrespective of the functions that can be performed by the graphic data encoding apparatus and the functions that can be performed by the graphic data decoding apparatus, the graphic data decoding apparatus,which is in accordance with a graphic profile, can completely restore a 3D mesh model described in the bitstream generated by the graphic data encoding apparatus that is satisfactory to the graphic profile.
