A method performed by at least one processor of an encoder comprises: performing, on an input 3D mesh, a symmetry detection process to estimate a partition plane. The method further comprises partitioning the input 3D mesh into a first side and a second side based on the partition plane, where the first side is opposite to the second side, and where a first vertex on the first side is symmetric to a second vertex on the second side. The method further comprises quantizing the first vertex and the second vertex in pairs to reduce a quantization error and symmetry prediction error associated with the first vertex and the second vertex.
