Open Toolkit (OpenTk) 是一个强类型的跨平台 OpenGL 和 OpenAL 封装，适应 C# 和 Mono以及.NET 平台。可以在 GTK# 以及 WinForms 应用中独立的运行。
主要特点：
Strong-typing.
Strongly-typed OpenGL and OpenAL bindings help you catch errors before they get a chance to manifest.
Integration.
OpenTK can be used standalone, as a Windows.Forms.Control or as a GTK# Widget.
Deployment.
OpenTK is a single dll that works on all platforms without recompilation (Windows, Linux and Mac OS X).
Rapid development.
OpenTK has extensive inline documentation, while strong types and intellisense simplify OpenGL and OpenAL code.
Optimization.
OpenTK plays well with the Garbage Collector - no memory is allocated while your program is running.
