Two High Capacity Methods for Embedding Public Watermarks into 3D Polygonal Models

Two methods are presented which allow to embed public readable watermarks into three dimensional models consisting entirely of triangles. The algorithms alter only the geometry and they don t require the mesh to have special properties, most noticeably they don t require it to be 2-manifold. The mesh of the three dimensional model does not need to be closed or orientable. For one of the algorithms even no connectivity of triangular faces is required
