EastDraw

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。 )

说明：  通过使用dxflib库，对dxf文件进行读取(Read DXF files by using the dxflib Library)

说明：  vc ++ 6.0 实现的各种统计图，线图，饼图，直方图(Charts including pie，line and bar chart)

MFC做的画图软件 只能画直线 还有待改进 适合初学者 看看(MFC do draw a straight line drawing software can be improved for beginners look)

ACIS的动态链接库，是AUTO CAD的几何内核(The dynamic link library ACIS is AUTO CAD geometry kernel)

80 纤维取向为设置的方向，20 为随机。利用Koch曲线模拟非织造纤维网。(we simulated various kinds of nonwovens through programming with Visual basic,in which 80 fibers are oreintation,20 are random. )

说明：  用VB编写的简易的绘图程序，用来绘制直线圆和矩形，可以选择绘图颜色和画笔粗细。(VB, easy to use drawing program, circles and rectangles to draw a straight line, you can select the drawing pen color and thickness.)

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)

用四阶龙格-库塔法求系统在U单位阶跃输入下该系统的响应曲线(Using the four order Runge Kutta method to find the response curve )
