DDA算法画直线，可以实现在网格下逐点画直线。(DDA algorithm for drawing straight lines, can be achieved in a grid-by drawing straight line.)

实现从SDK到MFC的封装 增加了绘制线条 矩形 椭圆等功能 而且可以变换颜色(none sdk to mfc)

可以实现基本的绘图功能，画直线，矩形，圆椭圆。图形学作业(Can achieve the basic drawing functions and draw a straight line, rectangle, circle, ellipse. Graphics jobs)

简单画图板，初学者实用，比较简单，如果喜欢可以下载来看看(Simple drawing board, beginners practical, relatively simple)

自动绘制保护煤柱,CAD 二次开发的，输入参数后，自己就绘制出来了(Automatic drawing protection pillar, CAD secondary development)

AE实现加载CAD格式的数据，以及对其进行转换格式，转换为SHP等格式，还有对其进行编辑等操作(AE spatial data editing functions, including generating points, generating lines, as well as delete, move elements such as fried operation)

用于拟合椭圆的函数，支持对于多个离散数据点的椭圆曲线方程计算(new function)

MFC 画出简单的坐标 并通过按钮产生随机点坐标（横坐标逐渐增大纵坐标随机）存入文件中 另一按钮实现读出数据并将点连成折线(MFC drawing simple coordinate and through the button generates random point coordinates (abscissa increases ordinate random) into a file and another button to achieve read data points connected into line)

观察Autocad内部数据组织的最佳工具,这个对应Autocad2(observation Autocad internal data organization the best tools, and corresponding Autocad2)

说明：  计算机图形学实验，完成立方体的三视图和等轴侧投影(Computer graphics experiments, the completion of three cube view and isometric projection)
