说明：  三相电压的整流到逆变，基本模型，可以参照设计，进行其他改造完善来适合自己程序的需要(Three-phase voltage of the rectifier to the inverter, the basic model, can refer to the design, improve the other transformation procedures to suit their needs)

lab1d是简单的QtSim软件，执行结果为enter numbers，然后输入您想读取的数字，然后继续进程得到anwser(simple QtSim file,this file shows u the difference between the .asii and .asiiz .)

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))
