本系列文章的第一篇文章重点介绍了OpenGL的主要窗口创建和设置。这篇文章会更有趣，因为我们将能够加载和显示图形文件，并显示一些动画。我们还将看到如何有效地管理这些资源。你在文章的顶部看到的图片是我们将在文章的结尾看到的。这还不是游戏，因为它没有任何游戏逻辑：它做的唯一事情是能够在屏幕上移动角色并正确地动画它。

这是一个已知但不同的益智游戏。不包括拼图的图像；事实上，图像是从桌面抓取的！首先，您可以选择游戏的难度：容易，中等，难，并通过按开始按钮，游戏将在您指定的秒数（默认为2秒）后开始。

For a while now, I have been looking for a solution to a chat program developed in VB.NET, but didn't find much, so I decided to try my own. The purpose of this article is to explain how to use TCP/IP Sockets and the My.Settings class included in .NET framework 2.0 and later. The good thing about this application is, the server and the client are not two separate applications. This form acts as both the Server and the Client.

JPEG is one of the most widely used standards for encoding photographs, pictures, or other visual content. But, the internal workings are mostly overlooked. We are used to using image.Save("filename",Imaging.ImageFormat.Jpeg);, but what's going inside image.save(); remains a big mystery for the programmer. Most of the available implementations of JPEG Encoder/Decoder are in C/C++. But, for a project, my friend 'anirban' required a JPEG encoder in C#. So, we started writing our own encoder. It turned out to be very complex and difficult. The one we wrote from scratch was really-really slow.. some functions had fourth order complexity (mostly the DCT part). Somehow, we managed to get some 'C' code from a forum. I converted parts of the 'C' code to C#; it was tedious work, but it worked pretty fast due to the fast DCT (AA&N).

将视频数据直接保存成jpeg图片， 也就是*.jpg图片上， 生成4K图片大约耗时200ms，效率比较高
