使用MATLAB 6.5开发，DDA算法画直线

不用图形库函数的仿windows画图程序 这是最近做的计算机图形学实验，其界面是一个仿Windows下的窗口界面，程序具有较好的交互性。全部的图形函数都没有用C语言自带的图形库函数，所写的函数都是直接写屏实现的，模拟了大部分图形库函数的功能。但也有部分没有写出，如保存图形块的getimage()等函数。由于水平有限，还有部分功能没有实现，如保存或打开BMP图片等。等有了时间再说吧。算法什么的写的很潦草，都随便说说的，欢迎高手指点，希望与广大C语言爱好者共同学习讨论。 -No graphics library function like windows drawing program to do this is the recent experiment of computer graphics, the interface is an imitation of the window under the Windows interface, the program has better interactivity. All graphics functions are not used C language graphics library built-in function, written by direct write screen functions are achieved, the majority of simulation graphics library function function. However, some did not write, such as the preservation of graphical block getimage () function and so on. Due to the limited level, there are some features did not realize, such as saved or opened that BMP pictures. With time, etc. later. What algorithm is written in the scrawl, are casual, welcome expert guidance, I hope with the

二维图形交互软件，可以画直线，圆，椭圆， 多边形，曲线，可以选取颜色-interactive 2D graphics software, can be painted line, circle, ellipse, polygon, curve, select colors

Meshlab和VCGlib都是意大利国立研究院的作品，meshlab提供了大量的模型分析与处理的算法，而VCGlib建立了基础的数据结构及其遍历访问的算法，也提供了模型的基本处理算法。VCGlib是标准C++库写的，其提供了IO与封装OpenGL来显示。Meshlab的界面是用QT来写的，因此需要QT SDK的支持。
