The Open Toolkit library is a fast, low-level C# wrapper for OpenGL, OpenAL & OpenCL. It also includes windowing, mouse, keyboard and joystick input and a robust and fast math library, giving you everything you need to write your own renderer or game engine. OpenTK can be used standalone or inside a GUI on Windows, Linux, Mac.
Open Toolkit库是OpenGL、OpenAL和OpenCL的快速低一级的C#包装器。它还包括窗口、鼠标、键盘和操纵杆输入以及健壮快速的数学库，为您提供编写自己的渲染器或游戏引擎所需的一切。OpenTK可以独立使用，也可以在Windows、Linux和Mac上的GUI中使用。
The Open Toolkit library is a fast, low-level C# binding for OpenGL, OpenGL ES, OpenAL, and OpenCL. It runs on all major platforms and powers hundreds of apps, games and scientific research.
Use OpenTK to add cross-platform 3d graphics, audio, compute and haptics to your C# application. Integrate it into your existing user interface or use it standalone without any external dependencies.
OpenTK comes with simple and easy to follow tutorials for learning modern OpenGL. These are written by the community and represent all of the best practices to get you started.
Open Toolkit库是OpenGL、OpenGL ES、OpenAL和OpenCL的快速低级C#绑定。它在所有主要平台上运行，为数百个应用程序、游戏和科学研究提供动力。
使用OpenTK将跨平台的三维图形、音频、计算和触觉添加到C#应用程序中。将其集成到现有的用户界面中，或在没有任何外部依赖关系的情况下单独使用。
OpenTK附带了简单易学的教程，用于学习现代OpenGL。这些都是由社区编写的，代表了开始的所有最佳实践。
OpenTK is not a game engine, nor does it try to be one: It offers a useful set of tools and lets you decide how to use them. It is the ideal starting point if you want to write a game or scientific application from the ground up.
OpenTK不是一个游戏引擎，也不想成为那样一个：它提供了一套有用的工具，让你决定如何使用它们。如果你想从头开始写一个游戏或科学应用程序，这是一个理想的起点。
