A method and an apparatus are disclosed for patch-based mesh coding. In the disclosed embodiments, a mesh decoding device decodes a bitstream to reconstruct patch information and a patch-based base mesh. The mesh decoding device reconstructs base mesh vertices and connectivity by using the patch information and the patch-based base mesh. The mesh decoding device generates predicted vertices and connectivity based on the reconstructed base mesh vertices and connectivity. The mesh decoding device decodes a bitstream to reconstruct a transform-coefficient image, and reconstructs vector differences of vertices by unpacking, inverse quantizing and inverse transforming the transform-coefficient image. The mesh decoding device adds the predicted vertices and the vector differences to reconstruct mesh vertices and connectivity.
