Abstract
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.
