本程序实现了计算机图形学的一些重要算法（画直线，画圆，画椭圆，区域填充，图形裁剪，齿轮生成，三次样条曲线等等），源码和可执行程序均打包于文件中(this program is implemented some important algorithm of computer graphics such as drawing lines,drawing circles,drawing ellipse,area filling,Graphics clipping，gear wheel generation ，three times spline curve and so on），source code and executable files are all included in the compressed file。 )

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)

该程序实现了图形学中的一些算法，如画线、画圆，填充、直线多边形、扫描转换，扫描线消隐算法以及一个简单的Gouraud光照模型。(the realization of a number of graphics algorithms, painting lines, the Circle, filling, linear polygon scan conversion, Lines scanning algorithm and a simple scan illumination model.)

用于C/C++/Visual C 二二维等值线的绘制，程序源码 (Drawn for two two-dimensional contour of the C/C++/Visual C program source)

DDA直线绘制程序实现，可以是任意的直线。(DDA line drawing program, a straight line can be arbitrary.)

DFX格式的文件操作例子,可以读出由CAD绘制的保存为DFX格式的图片,附带大量注释(DFX format file manipulation example, can read out by the CAD drawing for the preservation DFX format photographs, Notes of a large number of fringe)

随机生成一堆杂乱数据，借助RANSAC和贝塞尔样条拟合出曲线形状，使之最大程度拟合数据(Do the three degree Bezier Spline fitting based on RANSAC)

基于Bresenham算法的四步画直线算法,加快画直线速度(draw line based Bresenham update alogrith)
