| Abstract: | Since the protection of intellectual property in 3D graphics and encryption of information are more and more important,people began to use the information hiding technology to add a digital watermark or to use 3D graphics information hiding technology to encrypt important information.The information hiding technology in 3D graphics is introduced in this paper and the hiding algorithm based distance-invariance is investigated.Finally the algorithm is verified by triangular grid Cow 3D model in ply format. |

| Keywords: | 3D graphics information hiding hiding algorithm distance-invariance |
