| Abstract: | In the process of rendering for large terrain, producing images clearly and accurately are required. This paper puts forward the reasonable solution from the organization of the real-time terrain data, drawing LOD selection standards, LOD optimization and optimization of view frustum culling. The result shows that the method can make full use of GPU draw, which can be applied to rendering for large scale terrain. |
