Level of Detail (LoD) is a key technique for real-time rendering. A new real-time rendering algorithm incorporating view-independent algorithms and view-dependent algorithms is presented in this paper. Firstly, a polygonal mesh model is symplified view-independently according to the different requirements of applications or the user-specified error. Then the simplified model is used in a view-dependent real-time rendering algorithm. Examples illustrate that the proposed mesh simplification algorithm and rendering algorithm can accelerate the rendering speed greatly, while the rendering error (evaluated by pixel) is very small.
