这是一个包含直线的话法，圆 的填充的代码

新手向的代码，很容易看懂，就是注意分类器的位置，我们会将摄像头所摄下的视频一帧一帧的图片，一个个来进行单独的人脸识别，并且把识别出来的人脸用各种颜色的椭圆标示出来。

用c语言编写的画圆球，椭圆的程序，不是用图形库-used language paintings balls, oval procedures, instead of graphics library

基于API的图像采集程序-image acquisition procedures

画了一个五角星并添充了颜色，还用微分画直线法，和bresenham法画直线-drawing of a five-pointed star and Tim added color, differential line drawing, and painting straight bresenham France

VC6下VTK体绘制，然后boxwidget多角度任意切体数据-VTK volume rendering under VC6, and then arbitrarily cut boxwidget multi-angle data

饼图绘制控件,用C#编写的,非常好的图形控件,用于ASP.NET-pie drawing controls, use the C# prepared, very good graphics control for ASP.NET

这是用VC6.0编写的绘制三次Bezier曲线的程序，使用MFC框架文档视图结构。程序除实现三次Bezier曲线的绘制，还实现了点，直线，圆的绘制，可做为学习计算机图形算法的参考。与其它Bezier曲线绘制程序的不同是，本程序实现了Bezier曲线上型值点的计算显示。程序中编写了Bezier曲线类来完成Bezier曲线的绘制，并能对绘制的曲线数据进行保存与打开。对学习文件操作也有一定帮助。这是我第一次上传源码，有什么不妥之处还请管理员指点。谢谢！-VC6.0 prepared by the cubic Bezier curve drawing procedures, use MFC framework document View structure. In addition to procedures to achieve cubic Bezier curve drawing, but also realized the point, line, round mapping, can be used as learning computer graphics algorithm reference. And other Bezier curves of different procedures, The program of Bezier curve-point value calculations show. Procedures prepared Bezier curves like to complete the Bezier curve drawing, and is able to draw the curve data preservation and open. Operation right to study the documents will also help. This is the first time I uploaded the source code, what is wrong with this manager also requested guidance. Thank you!

很好用的3D动画引擎源代码，计算机图形学几何工具算法详解/Geometric Tools for Computer Graphics 配套源代码。由于网络不通畅，我去掉了原包中的例子和数据，仅留下代码库。-Good use of 3D animation engine source code, computer graphics, geometric algorithms explain tools/Geometric Tools for Computer Graphics matching the source code. As the network is not open, I removed the original package examples and data, leaving only the code library.

qt的中级代码实例，可以用来继续深入学习qt编程架构和各个模块的适用方法-qt examples of the intermediate code can be used to continue programming qt-depth study of the structure and application of methods of each module
