Abstract: This paper proposes a kind of based on dynamic LOD (level-of-the detail) multi-control factors of the three-dimensional terrain rendering algorithm, this algorithm improved the traditional LOD terrain rendering algorithm. Firstly, the nodal evaluation system is constructed according to the horizon, surface roughness, and the point of view velocity, at the same time, the four-point view elimination method and the edge addition method are used to eliminate cracks. The experimental results show that compared with the traditional quadtree algorithm, this algorithm can effectively reduce the rendering of useless vertices and significantly improve the rendering efficiency.
