QR码编码源代码，无需动态链接库，在VC或VS下运行工程，实现QR码编码，可以调版本，错误等级，掩模模式，可以保存图像。注释是日文，功能很强大。适合喜欢研究二维码或QR码的同学学习和研究。

应用背景 基于Astar算法的最优路径生成算法实现： 可应用于地理建模后的道路自动生成，实现人工智能中Astar最优路径选择功能，可辅助道路设计师； 计算机可视化领域的demo 关键技术 包含Astar算法实现，使用qt编写界面ui，使用osg三位渲染引擎加载三维地形，并显示可视化路径。 可鼠标点击生成路径的起点和终点，具备良好的ui交互。

自己写的形态学的寻找连通域的实现方法。调用了自己写的腐蚀和膨胀函数-Morphological write their own search for the realization of methods connected domain. Call to write their own corrosion and expansion function

一个绘制网络拓扑结构的图的vc代码，可以直接约束求解，而且可以用箭头直线连接2个网格图形！-A mapping of network topology map vc code, you can direct constraint solving, but also can use the arrow straight line connecting two grid graphics!

一阶系统时间响应曲线-a band system time response curve

3d与 vc opengl 的结合 ，对初学者的帮助应该很大-Vc opengl and 3d combination of help for beginners should be great

二维图形软件，可以实现简单的二维图形的绘制-2D graphics software, can achieve a simple two-dimensional graphics rendering

This is a plugin script for Go-ogle"s free 3D design program Sketchup. The free version of Sketchup has limited file export options and many CAM programs will not recognise the native Sketchup (SKP) file format. This plugin allows you to export your Sketchup model as a DXF or STL files readable by most CAM and 3D printer software.Using the pluginAfter copying this file, start Sketchup and you should now have an extra menu option (Export to DXF or STL) in the Sketchup Tools menu.There are five export options:STL  triangles. Use this for Makerbot or Reprap style 3D printersDXF polyface mesh. This will give the most faithful reproduction of your original Sketchup model.DXF polylines: exports the outlines of each face as a polyline, sometimes useful for CAM toolpaths.DXF triangular mesh: breaks all the faces up into trianglesDXF lines. This

用C++实现画线功能，程序用MFC的类来实现，很实用的程序。-C++, drawing a line function to achieve the program using MFC classes to implement, very useful program.
