Claim 8:
9. An apparatus comprising:
a non-transitory memory for storing an application, the application for:
performing mesh voxelization on an input mesh;
implementing patch generation which segments the mesh into patches including a surface mesh and unprojected triangles;
performing mesh coding on the surface mesh;
performing triangle coding on the unprojected triangles; and
generating a Visual Volumetric Video-based Compression (V3C) bitstream based on the mesh coding and the triangle coding, wherein triangle coding includes determining if a bounding box of connected components is smaller than a pre-defined area, the unprojected triangles are moved to a separate list for independent triangle coding, and the unprojected triangles are not rasterized, but coded as vertices with associated color per vertex; otherwise, each triangle is projected to a patch, and if a projected position of a vertex is already occupied, the triangle is encoded in another patch, so the triangle is put in a missing triangles list to be processed again later; and

a processor coupled to the memory, the processor configured for processing the application.
