Standardization Status of MPEG Video-based Dynamic Mesh Coding (V-DMC)

3D dynamic meshes are extensively utilized to represent immersive 3D content. The need to transmit a vast quantity of these captured dynamic meshes over networks has created a significant demand for efficient dynamic mesh compression techniques. In response to this critical requirement, the Moving Picture Expert Group (MPEG), an international standard working group of ISO, initiated a new project in October 2021, called Video-based Dynamic Mesh Coding (V-DMC). This initiative seeks to leverage existing, mature video codecs and their prevalent hardware as well as direct usage of future video coding solutions. The inaugural version of the V-DMC test model was released in July 2022. Over the past two years, continuous efforts have led to the development of V-DMC test model version 8.0. This paper aims to detail the technical advancements and provide an update on the current status of V-DMC standardization activities.
