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 )

mfc 实现绘制3次B样条 效果很好 模块化可以在自己论文中使用(mfc achieved drawing cubic B-spline)

实现本机流量监控绘图，测试可用，方便安全(Netflow monitoring)

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)

dxflib-3.3.4-src ，dxflib是一个用来读写DXF文件的C++库。当读DXF文件的时候,dxflib分析文件并且调用用户自己定义的函数来添加实体、层、等。(dxflib-3.3.4-src，dxflib is an opensource C++ library for reading and writing AutoCAD (R) DXF files. )

电力系统绘图程序源码,对开发GIS系统的程序员有一定的帮助(VC++ electrotic DRAWING PROGAM)

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)

mfc 实现绘制3次B样条 效果很好 模块化可以在自己论文中使用(mfc achieved drawing cubic B-spline)

手动绘制点，自动生成样条曲线，可以拖动修改点来修改样条曲线(Manually plotting points, automatically generated spline curves, you can drag the modified point to modify the spline)

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)
