中点画圆与中点画直线 二维图形变换 多边形填充 计算机图形学实验(The midpoint Circle draws line in two-dimensional graphics transform polygon fill, computer graphics experiments)

unicet和netdraw使用手册，能够较好的学习这两种软件，用于网络绘图(unicet, and netdraw use the manual, better able to learn both software for network drawing)

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VB程序可以将外部输入的数据以图形的方式画出，提供了一个参考,并有图形刷新功能，很详细的介绍了VB的画图功能(The VB program can draw the external input of data in graphical form, to provide a reference, and graphics refresh function, a very detailed description of the VB drawing functions )

利用逐点法绘制出图形，图形的绘制其实都是由折线组成的，只是每条折线的误差太小了，肉眼根本分辨不出来(use of the point-by-point drawing graphics, the graphics are actually drawn from the composition of the dogleg, only broken each of error is too small, the human eye can not be seen)

当用户按下鼠标左键在如下图所示的面板上移动鼠标时，根据鼠标的移动轨迹在面板上画图。(When the user presses the left mouse button on the panel as shown in the following figure to move the mouse, according to the mouse movement trajectory in the panel drawing.)

用牛顿插值法绘制曲线,同时涉及vb与excel的连接！,(Newton interpolation method are used to draw curves, at the same time involved in vb connection with excel!)

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。 )

简单计算机图形学算法，通过直线中点Bresenham算法,绘制直线。( Simple computer graphics algorithms, Bresenham line passing through the midpoint algorithm, draw a straight line.)

本代码是进行齿轮参数设计和参数校核，参数化绘制二维工程图的源代码(gear parameters for the design and verification parameters, parametric mapping of two-dimensional engineering drawings source code)
