LOD技术研究（参考书和代码）

代码说明：

说明：  LOD技术即Levels of Detail的简称，意为多细节层次。LOD技术指根据物体模型的节点在显示环境中所处的位置和重要度，决定物体渲染的资源分配，降低非重要物体的面数和细节度，从而获得高效率的渲染运算。(LOD technology is the abbreviation of levels of detail, which means multi-level of detail. LOD technology is to determine the resource allocation of object rendering according to the position and importance of the nodes of the object model in the display environment, reduce the number of faces and the degree of detail of non important objects, so as to obtain efficient rendering operation.)
