英文摘要：

We present a comprehensive survey on up-to-date algorithms of 3D model watermarking techniques. Firstly, the features and the fundamental requirements of 3D watermarking are introduced. Secondly, various watermarking algorithms in spatial domain and transformed domain are analyzed and compared. The performance evaluation of 3D model watermarking is also studied. Finally, some open problems and future directions are discussed.
