欢迎来到OpenGL

从今天开始，如果时间允许，将会把http://learnopengl.com/ 内容进行翻译。英语水平有限，翻译的不准确的地方，希望大家斧正。关于OpenGL，共同学习，共同进步。

Welcome to OpenGL

欢迎来到OpenGL

Welcome to my humble attempt to facilitate a well-developed teaching platform for the graphics API called OpenGL. Whether you are trying to learn OpenGL for academic purposes, to pursue a career or simply looking for a hobby, this site will teach you the basics, the intermediate and all the advanced knowledge using modern (core-profile) OpenGL. The aim of LearnOpenGL is to show you all there is to modern OpenGL in an easy-to-understand fashion with clear examples, while also providing a useful reference for later studies.

欢迎来到这个平台来学习一种成熟的图形API叫做OpenGL。不管你学习OpenGL是出于学术目的,或者追求事业或只是寻找一种爱好,这个网站会教你modern OpenGL的基本知识、中级和高级知识。LearnOpenGL的目的是向你们用一个易于理解的方式（比如详细的示例）来展示modern OpenGL,同时也为后来的学习提供一些参考。

So why read these tutorials?

为什么要读这些教程?

Throughout the internet there are thousands of documents and resources on learning OpenGL, however, most of these resources are only focussed on OpenGL's immediate mode (commonly referred to as the old OpenGL) or are incomplete, lack proper documentation or are not suited for your learning preferences. Therefore, my aim is to provide a platform that is both complete and easy to understand.

互联网有成千上万的文件和资源来学习OpenGL,然而这些资源大多只关注OpenGL的即时模式(通常称为old OpenGL)或不完整模式,但都缺乏适当的文档或者就不适合学习。因此,我的目标是提供一个平台,完整又容易理解方式来学习OpenGL。

If you enjoy reading tutorials that provide step-by-step instructions, clear examples and that won't throw you in the deep with millions of details, these tutorials are probably for you. The tutorials aim to be understandable for people without any graphics programming experience, but are still interesting to read for the more experienced users. The tutorials also discusses practical concepts that, with some added creativity, could turn your ideas into real 3D applications. If all of the previous sounds like someone that could be you, then by all means, please continue.

如果你喜欢阅读那些有着一步一步的介绍,有着明确的例子的教程,但是却不会迷失在细节里,此教程可能适合你。此教程的目的是可以让那些没有任何图形编程经验也可以理解OpenGL,当然，对于有经验的读者，此教程也有很多有意思的内容。此教程还讨论了实用的概念,你可以加些创造力把你的想法变成3D应用程序。如果以前有所迟疑,那么在这里无论如何,请继续下去。

What will you learn?

你将学到什么?

The focus of the tutorials are on Modern OpenGL. Learning (and using) modern OpenGL requires a strong knowledge of graphics programming and how OpenGL operates under the hood to really get the best of your experience. So we will start by discussing core graphics aspects, how OpenGL actually draws pixels to your screen and how we can abuse that knowledge to create some funky looking effects.

教程的重点在于Modern OpenGL。学习和使用Modern OpenGL需要扎实的图形编程知识，OpenGL如何运作在引擎盖下面带给你最好的体验。所以我们将首先讨论核心图形方面的知识以及OpenGL如何将像素绘制到屏幕上。我们可以用这些知识创造一些绚丽的效果。

Aside from the core knowledge we will discuss many useful techniques that you can use for your applications like walking through your scenes, create beautiful lighting, load custom-made objects from a modelling program, do cool post-processing techniques and much more. Over time, we will also feature walkthrough tutorials where we actually create small games based on our obtained OpenGL knowledge, so you will really get a feel of what it's like to actually do graphics programming.

除了核心知识我们将讨论许多有用的技巧,您可以使用您的应用程序来使你走进你的场景,创建美丽的灯光,从造型程序装载定制的对象,很酷的后处理技术等。随着时间的推移,我们的教程将会着重于创建基于OpenGL的小游戏,所以你将真正的感觉什么是图形编程。

Update 07-08-2016: At the moment I'm working on an educational graphics engine (that will be part of a graphics engine tutorial) meant to serve as an educational tool for people wanting to learn how to build a complete graphics engine and for myself to fully understand some of the more recent render techniques. Building such an engine helps me develop the resources and knowledge I need for further tutorials down the line (such as IBL, SH, PBR). For this reason (and the fact that it's difficult to find spare time for me now) there haven't been much new tutorials lately. The moment the graphics engine is built, I'll fully devote myself to writing new tutorials again (and set up the Patreon account I've mentioned).

更新于07-08-2016:此刻我正在做一个教育图形引擎(这将图形引擎的一部分教程)旨在作为一个教育工具,来教用户学习如何构建一个完整的图形引擎这是我自己所理解的一些最新的渲染技术。建立这样一个引擎有助于增加我的资源和知识为进一步的教程(如IBL SH,PBR)服务。因此(事实上,对我来说现在很难找到空闲时间)最近没有新的教程。图形引擎建立完成的那一刻,我将全身心的投入自己编写新的教程(我提到过的设置Patreon帐户)。

Best of luck in your OpenGL adventures!

祝你在你的OpenGL学习中有所收获!

Update 11-05-2016: It's been ages, but I've finally been able to release a new tutorial: the debugging tutorial in the In practice section is now available to everyone. I've also built a new code viewer that directly takes the source code from the GitHub repository. This is great as this means the GitHub code directly corresponds to the tutorial code. All new tutorials will use the new code viewer, and I'll slowly start moving the older code to the new code viewer as well.

更新于11-05-2016:时光飞逝,但我终于能够更新一个新的教程:在实践中部分的适用于每一个人的调试教程。我还建立了一个新的代码查看器,可以直接从GitHub获取源代码。这意味着GitHub代码直接对应于本教程的代码。所有新教程将使用新代码查看器,我也会慢慢得移动老代码到新代码查看器。

Update 21-04-2016: I just updated the website a little with some small layout changes and updated the page loading routine to fix a few little bugs. I've been quite busy lately, but I plan to slowly get back on track to writing new tutorials again. I'll likely be setting up a Patreon page soon so that I could perhaps take a day off from my day-to-day job to fully focus on writing tutorials. Expect new stuff soon; happy learning!

更新于21-04-2016:我刚刚对网站做了一些小更新，布局的变化和更新页面加载程序的bug。最近我一直很忙,但我打算慢慢回到正轨再编写新的教程。我可能很快就会建立一个Patreon页面,这样我就可以专注于写新的教程。预计新的教程很快会更新,祝大家学习快乐!
