The Open Toolkit is an advanced, low-level C# library that wraps OpenGL, OpenGL ES and OpenAL. It is suitable for games, scientific applications and any other project that requires 3d graphics, audio or compute functionality.

This is the official GIT repository of the project:

https://github.com/opentk/opentk

• Create cutting-edge graphics with OpenGL 4.4 and OpenGL ES 3.0.

• Integrate 3d into Windows.Forms, WPF or GTK# applications.

• Write once run everywhere: support for Windows, Mac OS X, Linux, Xamarin.Android and Xamarin.iOS.

• Use strong types and inline documentation to improve your code flow and catch errors sooner.

OpenTK is designed to be used in an IDE with auto-completion and documentation tooltips:

• Visual Studio 2005 or higher
• Xamarin Studio 2.x or higher
• MonoDevelop 2.x or higher
• SharpDevelop 3.x or higher

You can develop on your favorite operating system. Compiled binaries can be deployed without recompilation on:

• Windows
• Linux
• Mac OS X

For:

• Android
• iOS you will need to recompile your code with Xamarin (http://xamarin.com/download)

The Documentation/ folder contains extensive documentation on OpenGL, OpenGL ES and OpenAL. Start with these:

• OpenGL 4.4 API Reference.pdf or
• OpenGL ES 3.0 API Reference.pdf

Your favorite IDE will display inline documentation for all OpenTK APIs. Tutorials can be found in the OpenTK Manual

The community hangs out at the OpenTK forums
