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))

朋友写的C++645通讯程序，支持645-1997与645-2007,支持自已组帧程序自动添加校验码通讯，可以增加数据标识定义，里面还有部分关于费控通讯代码，挺好，拿来分享(Friend write C++645 communications program to support the 645-1997 and 645-2007, to support their own group the frame program automatically adds the checksum communications, can increase data identifies the definition, there is also a section on the fee control communications code, good for them and share)

说明：  非常好的OPC服务器源代码 免费的 没有时间限制(Very good OPC server source code for free no time limit)

用MFC实现了tif格式到bmp格式的转换，值得下载(Using MFC to achieve a tif format to bmp format conversion, it is worth downloading)

VC版绘图，直接在对话框中绘制曲线图，可以在二维与上位之间切换(VC version of the drawing, directly draw graphs in the dialog box, you can switch between two-dimensional and the host)

在Microsoft Visual C++6.0环境下，应用ADO，编写的连接access数据库的简单程序(MFC ADO access)

这是一款做的一个很不错的模型和骨骼动画系统，其中包含了针对3DS MAX的导出插件的源码，可供朋友们参考。(This is a very good models and a skeletal animation system, which contains the exporter plug-in for 3DS MAX source code, for friends as a reference.)

DC-DC变换器的DSP28335控制程序，采样TI的软件架构，实现软启动，闭环控制等(DC-DC converter DSP28335 control procedures, sampling TI software architecture, soft start, closed-loop control)

使用编写程序，实现一个坐标轴功能，进行数据分析与运算(Use programming to implement a function of coordinate axes, data analysis and calculation)

系统主要实现时间的显示，主要包括获取系统时间然后通过时钟的模拟界面进行时间的显示。(System main time display, including access to the system time and then displays the time by the clock of the analog interface.)
