测绘方面的道路中桩计算程序。缓和曲线、圆曲线。(Surveying and mapping aspects of the road in the pile calculation program. Curve, the circular curve.)

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)

用MFC实现画图板，包括绘线，几何图形，上色等等，简单易懂。(To realize drawing board with MFC)

说明：  计算机图形学实验，完成立方体的三视图和等轴侧投影(Computer graphics experiments, the completion of three cube view and isometric projection)

用vc+mapobjects开发的源代码，实现鼠标多边形的移动(with vc MapObjects development of the source code, mouse polygon mobile)

PSCAD仿真,可以设置各种故障,故障类型可以自由设置,并且得到故障仿真图形,本程序中附有单相故障(PSCAD simulation, you can set a variety of failures, fault types can be set free, and get fault simulation graphics, the program with a single-phase failur)

这是国外的同行编写的画图板程序，感觉比陈建春的要好些，说实话研究了半天，发现国内的cad水平低不是因为国内的人笨，主要是国外的cad技术不能很快的传递到国人手中，总是参考陈建华等水平有限，工程水平差的书籍造成整体水平低，书中没有详细的流程图，和软件设计思路，而且代码错误连篇。(This is the foreign counterparts of the drawing board to prepare procedures, CHEN Jian-chun than feeling the need to better tell the truth for a long time study and found that low levels of domestic cad because people are not stupid, mainly abroad cad technology should not quickly delivered to the the hands of the people always refer to Chen Jianhua, such as the limited level, engineering level difference caused by the overall level of books low, the lack of a detailed flow chart of the book, and software design, and code errors pack.)

图形学上机实验，用三种算法画线。包括Bresenham画线算法、中点画线和数值微分画线算法(Graphics on an experiment with three algorithms draw the line. Bresenham line algorithm, the dotted line and numerical differential line drawing algorithm)

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)

5/3小波变换的提升算法实现以及对于什么叫做提升的介绍。由于5/3小波是整数小波，因此非常适合于DSP处理，且经过提升，小波变换的复杂度明显降低，将此代码的提升部分移植到DSP上，可以达到实时。(5/3 wavelet transform algorithm to enhance as well as what is to enhance the introduction. Since the 5/3 integer wavelet wavelet is therefore very suitable for DSP processing, and after upgrading, wavelet transform significantly reduced complexity, the upgrading of part of this code ported to DSP, we can achieve real-time.)
