英文摘要：

Remeshing of 3D mesh models is an important task of computer graphics,and it is a key component of many geometric algorithms.In recent years,the rapid development of 3D applications,such as finite element modeling,computer animation,3D printing,requires higher quality of mesh,and promotes the rapid development of remeshing of 3D mesh models,resulting in many new remeshing technologies.In this paper,we first introduced the evaluation criteria of meshing quality.Then,we surveyed the latest development in isotropic remeshing and discussed the advantages and disadvantages of various remeshing algorithms.Finally,we discussed some new problems and directions for future research.
