Mesh Coding Extensions to MPEG-I V-PCC

Dynamic point clouds and meshes are used in a wide variety of applications such as gaming, visualization, medicine, and more recently AR/VR/MR. This paper presents two extensions of MPEG-I Video-based Point Cloud Compression (V-PCC) standard to support mesh coding. The extensions are based on Edgebreaker and TFAN mesh connectivity coding algorithms implemented in the Google Draco software and the MPEG SC3DMC software for mesh coding, respectively. Lossless results for the proposed frameworks on top of version 8.0 of the MPEG-I V-PCC test model (TMC2) are presented and compared with Draco for dense meshes.
