In this paper, we provide an overview of the reconfigurable graphics coding (RGC) framework, in MPEG, and we present the design of 3D mesh coding based on the RGC framework. In 3D graphics, there exist many overlapping object types (e.g., IndexedFaceSet in VRML, Mesh in Collada, etc.) in various formats. In order to design a standard that supports many different object types and their combinations, the MPEG RGC framework is proposed as a unified framework that covers everything, from object type definition to object compression, in a modularized approach. The RGC framework is largely based on the reconfigurable video coding (RVC) framework in MPEG. Currently, the RGC framework further extends the RVC to support a generic object type definition. In this paper, we provide a walkthrough on the use of the RGC framework with existing graphics coding standards such as MPEG 3D mesh coding.
