Abstract
An apparatus obtains a mesh representation of a 3D object, and performs an encoding process: segmenting the 3D object into 2D projections; encoding the segmented 2D projections into a bitstream; reconstructing a 3D mesh from the segmented and encoded 2D projections; deriving an error vector, describing a shift between 3D data, from patches reconstructed from corresponding encoded patches of the bitstream, and original data in the mesh representation. The patches are submeshes of the reconstructed 3D mesh. The apparatus signals and transmits the error vector in or along with the bitstream. A decoder apparatus receives these and performs a decoding process to form decoded 2D projections of the mesh representation, reconstructs a 3D mesh from decoded 2D projections, applies the patch correction vector elements from the error vector in the decoding process or the reconstructing, produces a modified 3D mesh, as an output mesh and outputs the output mesh.
