Watermarking of 3D-polygon-based models with robustness against mesh simplification
Oliver Benedens · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1999
This paper presents a watermarking algorithm suitable for embedding private watermarks into three dimensional polygon based models. The algorithm modifies the models normal distribution to store information solely in the geometry of the model. The watermarks show significant robustness against mesh simplifying methods.
