英文摘要：

The recent arithmetic of watermarking of 3D models is summarized here. First, Some basic conceptions of watermarking of 3D models are introduced,then the typical arithmetic of space field and transform field are given. At last the diffculties of watermarking of 3D models are concluded and its applied fields and prospect.
