AddCAD

说明：  1． 做一个集成的图形界面的程序，可调用每一次作业子程序。 2． 调用画点的函数，用DDA、中点算法画直线和中点算法及正负法画圆和抛物线。 3． 交互式的二维直线求交：如果存在交点，用实心圆显示交点，并用文字显示其坐标。 4． 用动画实现二维图形变换的各种算法，实现对指定形体的平移、旋转和缩放。（包括自行车行走和绕固定点旋转的自旋转物体动画。） 5． 线段裁剪和多边形裁剪算法的动画演示实现。（两种线段裁剪算法和H-S多边形逐边裁剪算法）多边形裁剪算法的动画演示要求先画出一个封闭的多边形，再画矩形的裁剪窗口，然后选择裁剪按钮（或命令），按下“上边裁剪”按钮（或执行“上边裁剪”命令），多边形相对裁剪窗口的上边进行裁剪，显示上边裁剪后的多边形，依此进行其它各边裁剪。 6． 两种扫描多边形扫描转换算法实现（扫描线算法为必做，基于求余运算的边缘填充和边标志算法任选一种）； 7． 4连通区域的递归种子填充算法，和扫描线种子填充算法，要求种子点(x,y)可交互输入）。 8． 简单三维图形系统：凸多面体的建模、透视投影，隐藏面的消除及基本图形变换（平移、旋转、缩放）。 9． 交互式Bezier曲线的输入绘制程序实现 (1. So an integrated graphical interface procedures, which call for each operation subroutine. 2. Calling the painting point function, with DDA, the midpoint algorithm painting line and the midpoint algorithm and France Circle and the positive and negative parabola. 3. Interactive 2D linear intersection : If there intersection with a solid circle indicates Nodal and writing to demonstrate its coordinates. 4. Using 2D animation graphics transform algorithms to achieve the specified physical translation, rotation and scaling. (Including walking and cycling around the fixed point of rotating objects from the rotating animation.) 5. Line cutting and polygon clipping algorithm to achieve the animation demo. (Two segments cutting algorithm and H-S-by-side polygon clipping algorithm) polygon clipp)

绘制多图形图表的强大功能库软件示例。请下载！(PGL is a library that encapsulates plot capabilities in a MFC project for VC6 and VC7. It is designed to be able to easily plot data generated in a project without the need of any external software.)

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!)

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.)

MFC实现的画板程序，能够画图并保存，适合初学者(Sketchpad program, implemented by MFC drawing and save for beginners)

二维简单多边形凸分解源代码以及详细的使用说明(Two-dimensional simple convex polygon decomposition of the source code and instructions)

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)

能够对通达信.lc5文件进行修改，主要是修改分钟数，这样可以在两年多的数据中进行画线处理(Mastery letter. Lc5 file to be modified, modify the number of minutes, so you can draw lines in more than two years of data)

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))

VC动态绘制图像 真的 很好(VC dynamically drawn image very good)
