We show how to use fixed bases for efficient spectral compression of 3D meshes. In contrast with compression using variable bases, this permits efficient decoding of the mesh. The coding procedure involves efficient mesh augmentation and generation of a neighborhood-preserving mapping between the vertices of a 3D mesh with arbitrary connectivity and those of a 6-regular mesh.
