Data hiding on 3D polygonal meshes [PDF]

Proceedings of the 2004 workshop on Multimedia and security, 2004
This paper presents a high-capacity method to embed information into the geometry of a 3D polygonal mesh. The method extends a previously reported work, to which several improvements have been brought. By construction, the new embedding algorithm is robust against rotation, scaling and translation attacks.

Mechanical Characteristics of the Main Tower of a Polygonal Line Tower Cable-Stayed Bridge

Advances in Civil Engineering, 2020
The main tower of a polygonal line tower cable-stayed bridge bears most of the axial force transmitted by the stay cable and also bears the moment under certain unbalanced load. For a polygonal line tower cable-stayed bridge, the main tower has a bending
