%X This paper proposed a dynamic and seamless rendering scheme for large scale terrain based on LOD terrain tiles, used multi-resolution terrain for view-dependent data control and grid simplification, and employed multi-thread mechanism for visibility clipping and data exchange between memory and disk, at the same time, used an accelerating technique based on GPU for scene rendering, and proposed a seamless combination algorithm between tiles of terrain and texture. Experimental results of real scenes and comparisons with traditional method demonstrate the feasibility, efficiency and practicality of our me-thod.
