Abstract

This article presents a new compression scheme for 3D dynamic meshes, referred to as Video and Subdivision based Mesh Coding (VSMC). The VSMC approach combines a displaced subdivision surface model with video-based coding in order to achieve efficient compression performance and real-time, low-power decoding and playback. In addition, VSMC supports a rich set of functionalities including scalability (spatial, temporal, and quality) and progressive transmission. The proposed scheme [1] was shown to outperform the anchor for the MPEG Call for Proposals on Dynamic Mesh coding [2] and was recently selected by the ISO MPEG 3D Graphics Coding group as the basis for the upcoming Video-based Dynamic Mesh Coding standard.
