ASIFT算法

说明：  编译的图形软件的一部分程序可以画出直线圆弧矩形(graphics software compiler part of the procedure can draw straight rectangular arc)

本程序实现的是绘制一个单位立方体正平行投影图的程序，可以画出变换后的图形。运行环境为vc++6.0，内附有可执行文件以及所有源代码。(Implementation of this program is drawing a unit cube are parallel to the projection of the program, you can draw the transformed graph. Operating environment for vc++6.0 there is an executable file containing the source code and all.)

三视图，用二维图像显示三位图像，分主视图，俯视图，侧视图(view)

我用VC编的一个画图程序：其中使用了切分视图(I VC series a drawing program : the use of split View)

OpenGL高级编程与可视化系统开发（高级编程篇）的随书源码-4，学习OpenGL的好东西-OpenGL Programming and Advanced Visualization System (Advanced Programming Part 1) the source-4 with books, learning the good stuff OpenGL (OpenGL high-level programming and visualization systems development (high-level programming chapter)-4 of the source with the book, learning OpenGL good things-OpenGL Programming and Advanced Visualization System (Advanced Programming Part 1) the source-4 with books, learning the good stuff OpenGL)

说明：  虚拟内窥镜关键技术研究 虚拟内窥镜技术（Virtual Endoscopy）是虚拟现实技术在现代医学中 的应用。它利用医学影像作为原始数据，融合图像处理、计算机图形学、科 学计算可视化、虚拟现实技术，模拟传统光学内窥镜的一种技术。它克服了 传统光学内窥镜需把内窥镜体插入人体内的缺点，是一种完全无接触式的检 查方法。虚拟内窥镜的研究旨在为医生提供诊断依据，还可应用于辅助诊断、 手术规划、实现手术的精确定位和医务人员的培训等。(Research on key technologies of virtual endoscopy virtual endoscopy (Virtual Endoscopy) is a virtual reality technology in modern medicine. It has made use of medical imaging as an original data, the integration of image processing, computer graphics, scientific visualization, virtual reality technology to simulate a conventional optical endoscope technology. It overcomes the traditional optical endoscope to be inserted into the endoscope body of the shortcomings of the human body is a no-contact inspection method. Virtual Endoscopy of the study was to provide diagnosis for doctors, but also applies to diagnosis, surgical planning, to achieve precise positioning of surgical and medical personnel training.)

漂亮的图标程序源代码(beautiful icon source code)

中心画圆 使用vc6.0实现 多多指教(draw a Circle use vc6.0)

简单起见，这里设定阈值为122，即最大灰度的一半(the sake of simplicity, this threshold value is set to 122, the largest gray half)

说明：  再来一个绘图程序，花了我一个上午时间才搞定。(then a drawing program, I spent a morning time to get.)
