A method and a system for compressing and restoring mesh data of a 3D mesh model are provided to quantize and store location data of each node relatively exactly as compressing ad storing the location data of each node with a less number of bits. A system for compressing and restoring mesh data of a 3D mesh model(100) comprise a mesh data acquisition unit(110), a cluster mesh generation part(120), and a local quantization unit(130). The mesh data acquisition part obtains mesh data from a 3D mesh model. The cluster mesh generation part produces a plurality of cluster meshes by using the mesh data. The local quantization unit applies each local coordinate system to the plural cluster meshes, and generates quantization data for each node by quantizing the location information of each node included in each cluster mesh.
