3D model compression in MPEG

3D polygonal mesh is the most commonly used representation for 3D graphic models. Compact and compressed representation of the 3D mesh is the major functionality of MPEG 3D mesh compression technologies. 3D mesh coding (3 DMC) in MPEG was first standardized in 2000 with the achievement of compression ratio of more than 40 times with reasonable quality. In order to extend 3 DMC with additional functionalities (e.g., efficient texture coordinate compression, support for animation/editing, etc.), 3 DMC extension (3 DMC-X) has been proposed and standardized. In this paper, we reviewed 3D model compression in MPEG in detail.
