Research on triangular mesh model dynamic simplification based on cost function

Model simplification is the main method to resolve the storage,transmission and contradiction between real-time rendering and hardware processing limitation of complex 3D model.This paper introduces technologies and algorithms relating to triangular mesh model simplification.Now the triangular mesh model simplification algorithm based on edge collapse is very complex.Combining Garland's quadric error metrics algorithm and Hoppe's progressive mesh algorithm,a new algorithm for triangular mesh dynamic model simplification based on cost function is proposed in this paper.
