Study of LOD terrain rendering algorithm based on GPU

Real-time rendering of large scale terrain has always been a hot research topic in the field of computer graphics, virtual reality and simulation research. With scenes becoming more complex and real-time rendering limited, a large number of LOD algorithms have been applied to terrain rendering. In this paper, we review some traditional terrain rendering algorithms, then we show an effective LOD terrain rendering algorithm, and implement it by GPU. At last, we compare those algorithms according to some criterions to show advantages of the algorithm based on GPU.
