MFC_draw

液滴在壁面上流动的程序 可以用 tecplot画图 效果很好(The flow of the liquid drop on the wall of the program can be used to draw the effect of Tecplot is very good)

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)

该程序实现了图形学中的一些算法，如画线、画圆，填充、直线多边形、扫描转换，扫描线消隐算法以及一个简单的Gouraud光照模型。(the realization of a number of graphics algorithms, painting lines, the Circle, filling, linear polygon scan conversion, Lines scanning algorithm and a simple scan illumination model.)

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.)

MFC画图程序,实现动态画直线、椭圆等功能(MFC drawing procedures, to achieve dynamic painting a straight line, oval and other functions)

该VB程序可以将外部输入的数据以图形的方式画出，提供了一个参考,并有图形刷新功能，很详细的介绍了VB的画图功能(The VB program can draw the external input of data in graphical form, to provide a reference, and graphics refresh function, a very detailed description of the VB drawing functions )

服装CAD源代码，可以进行bspline的打断分割割，裁减操作，而且还可以解析shx字库，进行标注等。 (Garment CAD source code can be bspline split the interrupted cut cut operation, but also can resolve shx font marked.)

利用逐点法绘制出图形，图形的绘制其实都是由折线组成的，只是每条折线的误差太小了，肉眼根本分辨不出来(use of the point-by-point drawing graphics, the graphics are actually drawn from the composition of the dogleg, only broken each of error is too small, the human eye can not be seen)

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)
