说明：  实现大规模室外场景渲染技术,本程序使用基于严格的四叉树的方法建立一个LOD算法，并用该LOD算法实现了一个视点相关的动态多分辨率地形。采用多遍地面纹理，亮度图等技术来照明场景。同时DEMO还实现了Billboard,运动模糊，的功能。程序采用C++，模块化的结构让程序具有很高的可扩展性。 (achieve large-scale outdoor scene rendering technology, the use of procedures based on strict quadtree methods to establish a LOD algorithm, and the LOD algorithm with a view to achieve the dynamic multi-resolution terrain. Many times using ground texture, brightness map technology to lighting scenes. DEMO while also achieving the Billboard, motion blur, function. Adoption of C, the modular structure allows procedures with high scalability.)
