AddCAD

该程序可以绘制出扇形，并且带有黑色边框。(The program can draw out the fan, and with a black border.)

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)

等值线函数.// As this code is ported from FORTRAN-77, please be very careful of the // various indices like ilb,iub,jlb and jub, remeber that C/C++ indices // starts from zero (0)(contour function.// As this code is ported from FORTRAN-77, please be very careful of the// various indices like ilb, iub, and* address, remember that the C/C indices// starts from zero (0))

这是我们计算机图形学的课程设计，有时间不放(This our computer graphics curriculum design, and a link to see time)

说明：  用VC++编写，MFC文档框架，是一个简易的画图小程序，在文档界面上画图(With VC++ Prepared, MFC framework document is a simple drawing of small procedures, the document interface drawing)

MFC画图程序代码，可画椭圆，直线，矩形，改线宽，打开保存，颜色等(MFC drawing code can draw ellipses, lines, rectangles, change the line width, open the saved, color, etc.)

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. )

2D图像渲染，比如反走样，mark等效果，编码风格很好，模版用的淋漓尽致(2D image rendering, such as anti-aliasing, mark, such as the effect of good coding style, the template used by most)

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 )
