大规模地形渲染，使用OPENGL 和 C++变成，使用ROAM经典算法，LOD算法化简提高效率。-massive terrain rendering, use OpenGL and C into use Applying ROAM classic algorithms, LOD algorithm Simplification improve efficiency.
一篇有关地形渲染的论文，以下是摘要： A primary difficulty in terrain rendering is displaying realistic terrains to the user at real-time frame rates. The brute force approach is usually too complex for real-time frame rates to be achieved. Several terrain-rendering te
