This paper presents two variations of a robust water-marking method for general polygonal meshes of arbitrary topology which can be used for copyright protection, tamper proofing or content annotation purposes. The proposed watermark is immune to translation, rotation, scaling, or affine transformation of the mesh and is hard to detect unless the exact encoding parameters are disclosed. Several examples demonstrate the effectiveness of the algorithm.
