Abstract
A method of compression of 3D mesh data using projections of mesh surface data and video representation of connectivity data is described herein. The method utilizes 3D surface patches to represent a set of connected triangles on a mesh surface. The projected surface data is stored in patches (a mesh patch) that is encoded in atlas data. The connectivity of the mesh, that is, the vertices and the triangles of the surface patch, are encoded using video-based compression techniques. The data is encapsulated in a new video component named vertex video data, and the disclosed structure allows for progressive mesh coding by separating sets of vertices in layers, and creating levels of detail for the mesh connectivity. This approach extends the functionality of the V3C (volumetric video-based) standard, currently being used for coding of point cloud and multiview plus depth content.
