AddCAD

实现了DDA直线生成算法画直线，Bresenham圆弧生成算法画圆弧(Achieve DDA line drawing algorithm to generate a straight line, Bresenham algorithm for drawing arcs arc generated)

观察Autocad内部数据组织的最佳工具,这个对应Autocad2(observation Autocad internal data organization the best tools, and corresponding Autocad2)

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))

画曲线图的c++例子，使用定时器去随机数的方式画图。(Draw the curve c example, use the timer to go the way of the random number drawing.)

PSCAD做的12模块H桥SVG模型，电流矢量控制，运行良好。(PSCAD do SVG module 12 H bridge model, the current vector control, work well.)

实现贝塞尔曲线的编程，即人为指定N个点，程序自动生成这N个点的贝塞尔曲线。(Programming Bezier curve, namely human specified N points, the program automatically generates N points Bezier curve.)

NT9200数字脑电图仪 的串行通讯及实时绘图程序。可借鉴里面的绘图程序。(NT9200 digital EEG instrument serial communications and real-time drawing program. Inside of the mapping process can learn from.)

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)

产生一批随机数，使用TeeChart进行绘图。是TeeChart学习很好的程序。(Produce a random number, using TeeChart for drawing. TeeChart learning process is good.)

单文档绘图工具，包括直线，曲线，扇形，圆形，圆角矩形，矩形等图形，还可以设置线条的颜色等属性。(Single document drawing tools including lines, curves, fan-shaped, round, rounded rectangle, rectangle and other graphics, you can also set the line color and other attributes.)
