AddCAD

说明：  一个模拟cad画图的程序,实现了直线,椭圆,圆,矩形等图形的画法.需要安装后才能查看源码和相关文档(cad drawing a simulation procedures to achieve a straight line, oval, round, rectangular and other graphics painting. Installed after looking at the source and related documentation)

基于频散曲线，选择抽样脉冲信号作为子波，推导出了合成单炮面波地震记录的理 论公式，并利用该公式，针对不同弹性层状介质模型的频散曲线合成了面波地震记录。(Based on the dispersion curve, select the sampling pulse signal wavelet derived synthetic single artillery surface wave seismogram theoretical formulas, and the use of the formula, seismogram synthesis of surface wave dispersion curves for different elastic layered media model.)

手动绘制点，自动生成样条曲线，可以拖动修改点来修改样条曲线(Manually plotting points, automatically generated spline curves, you can drag the modified point to modify the spline)

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)

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)

CAD下VBA二次开发，用来展高程点，txt文件，已经把离散点网格化了(CAD lower VBA secondary development, to show elevation point, txt file, has the discrete points of the grid)

VB版个性画图板附上源代码,有需要的就下载吧。(VB version of personality drawing board with the source code, there is a need to download it.)

用于拟合椭圆的函数，支持对于多个离散数据点的椭圆曲线方程计算(new function)

说明：  MFC坐标系的绘制，动态显示曲线，感兴趣的可以参考下~~(MFC frame rendering, dynamic display curves of interest can refer to the following ~ ~)
