【Abstract】 In this paper, the idea of subdivision was introduced, and the theory and method of Loop subdivision based on triangular mesh were elucidated. A subdivision framework of complex plough surfaces based on OpenGL platform, which works corporately with relational CAD system, finite element calculator and dynamic simulation system, was proposed. Several key technologies, such as the generation of initial meshes and the control of surface border ware discussed. The proposed methods can improve the design efficiency of a new complex surface of plough.更多还原
