此种模型绘制类似米字形的网格。由于整个过程递归调用绘图函数，所以可以根据误差判断绘制DEM的精细程度，从而绘制出不同精细程度的DEM，为解决漫游中数据量较大而引起的画面不流畅现象提供了模型基础。 本文并没有对LOD作研究，只是给出了四叉树的建立和遍历绘图的方法。 #include "Pt3d.h" //空间点类(主要记录空间点的x,y,z) (Rendering such a model similar to rice-shaped grid. Recursive calls as a result of the whole process of mapping function, so it can be judged according to the error map of the fine DEM, thus rendering a different degree of precision DEM, for the settlement of roaming in the amount of data arising from the larger screen does not provide a model of fluid based on the phenomenon. This article does not LOD for research, but given quadtree traversal of the establishment and mapping method.# Include Pt3d.h // space-point type (mainly recorded space points x, y, z))

假设系统中有两个分别名为P1、P2的进程及两台均可进行输入、输出操作的设备d1、d2。两个进程可以从两台设备中的任何一台输入数据，并可以向其中的任何一台设备输出数据。编写C程序，模拟操作系统中使用的设备缓冲区管理算法，完成上述进程的输入、输出操作及数据处理任务。(assumption that the system has two named P1, P2 and the process can be carried out two input, Output operation of equipment d1, d2. 2 process from two equipment of any one input data, and can assure them in any one piece of equipment output data. C. preparation procedures, the operating system simulation equipment used in the buffer management algorithms, completion of the admission process, operation and output data processing tasks.)
