读取DXF文件(2000,2002版本),包括了分层管理数据的思想,供大家参考(read DXF files (version 2000, 2002), including a hierarchical data management thinking, for your reference)

当用户按下鼠标左键在如下图所示的面板上移动鼠标时，根据鼠标的移动轨迹在面板上画图。(When the user presses the left mouse button on the panel as shown in the following figure to move the mouse, according to the mouse movement trajectory in the panel drawing.)

DXF文件格式说明，包中包含了dxf文件的所有组码的解释(DXF file format description)

可以批量绘制全潮海流观测的流速流向曲线图,以大潮为例.只需将观测数据写为xlsx格式,即可自动出图.可以支持多个xlsx文件批量绘制.(You can draw all tidal currents observed mass flow rate of the flow graph to tide Case observational data simply written as xlsx format, you can automatically plot can support multiple xlsx file batch rendering.)

二维均匀各向同性介质弹性波动方程有限差分波场模拟(Two dimensional homogeneous isotropic medium elastic wave equation finite difference wave field simulation )

3次B样条小波程序，用MATLAB写的，思想简单，但要建立好像不容易，大家看看(3 bspline wavelet program,using matlab language.The idea is not complex,but it is not easy to realize it.Hope all read.)

强大的开源画图控件Zedgragh，包含控件源码，Demo示例代码和帮助文档，分为Winform版和WebForm版。(Powerful open source drawing controls Zedgragh, including source control, Demo sample code and help document is divided into Winform version and WebForm version.)

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)
