C#从入门到精通，这就是下半部分，大家可以自己找上半部(C# From Novice to Professional, which is the lower half, you can find yourself on the half)

实现windows下的管道通信，可以通过管道实现cmd的命令交互，比如应用程序中需要通过ADB命令和设备通信，可以通过参考代码实现(Pipeline communication under windows can be achieved through the pipe CMD command interaction, such as applications need to communicate through the ADB command and equipment, you can achieve through reference code)

说明：  PLC动态库 vb编程 支持s7-1200(PLC Dynamic Library Support s7-1200)

说明：  动态创建数组模板，可以用该模板动态创建所需要的数组类(Dynamic Creation of Array Templates)

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))
