README

OpenTK

OpenTK is a large project. There are many components to work on, and we'd welcome almost any contribution. The community is friendly, welcoming and always ready to help you get your PRs merged!

We have a very active discord server, if you need help, want to help, or are just curious, come join us!

Discord

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.

Features

  • Create cutting-edge graphics with OpenGL 4.6 and OpenGL ES 3.0
  • Spice up your GUI with 3d acceleration
  • Improve your code flow with strong types and inline documentation
  • Windowing systems to help get you started
  • Input, and other game essentials.
  • Performant, highly optimized and reliable linear algebra library
  • Write once run everywhere

OpenTK is available for Windows, Linux, Mac OS X, *BSD and SteamOS. It can be used standalone or integrated into a GUI (Windows.Forms, WPF, GTK+, Qt, VTK, ...)

An old, unsupported version of OpenTK 1.0 may be included in the Xamarin Android and iOS distribution. The Xamarin fork is not supported or maintained by this project.

Adding support for mobile again is a future goal of the OpenTK project, but is somewhat frustrated by Apple's deprecation of OpenGL. Contributions to re-add support for these platforms are welcomed.

Instructions

OpenTK is available as a NuGet Package.
