网格模型简化的研究进展

myraggedright In computer graphics, the data quantity of triangle mesh which is used to represent 3D models is more and more big. Although it is helpful to present more geometric details, it is a huge challenge to storage, transmission, calculation and real-time rendering of the graphic data. To simplify the complex mesh models, which has become an important means to solve this problem. In this article, the domestic and foreign researches on mesh simplification are introduced. According to the characteristics of the applications, the basic framework and metrics of mesh simplification are analyzed and discussed. These common mesh simplification methods are classified and analyzed. And the outlook of mesh simplification is given.
