The Open Toolkit is set of fast, low-level C# bindings for OpenGL, OpenGL ES, OpenAL and OpenCL. It runs on all major platforms and powers hundreds of apps, games and scientific research. It provides bindings for GLFW windowing, input and a game loop, and is the perfect start for your own game engine. 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. Learn how to use OpenTK here: Sample projects that accompany the tutorial can be found here: We have a very active discord server, if you need help, want to help, or are just curious, come join us!


OpenAL bindings for dotnet from the Khronos openAL c library.


OpenGl and OpenGlEs bindings for dotnet from the Khronos openGL c library.


GLFW bindings for c# from the cpp GLFW library.

FIX: Fixed issue where setting `NativeWindow.WindowState = WindowState.Normal` while fullscreen would not exit fullscreen. (@Th3Dilli)
API: Added `NativeWindow.FramebufferSize`, `NativeWindow.OnFramebufferResize`, and `NativeWindow.FramebufferResize` to be able to properly get the framebuffer size of the window (useful on macos where framebuffer size is not equal to client size). (@NogginBops)
API: Added `GameWindowSettings.Win32SuspendTimerOnDrag` propery that allows the internal timer to be suspended while the window is moved or resized. Without this dragging the window will cause an abnormally large time delta since the last frame. (@MV10)
API: Made `NativeWindowSettings.Size` obsolete in favour of `NativeWindowSettings.ClientSize` (`NativeWindowSettings.Size` has always set the client size of the window, this namechange just makes this clear). (@MV10)
API: Added ability to override OpenAL and OpenCL native library search path by setting `OpenALLibraryNameContainer.OverridePath` or `OpenCLLibraryNameContainer.OverridePath`. (@NogginBops)
API: Added `NativeWindowSettings.AutoIconify` and `NativeWindow.AutoIconify` property to control if the window gets minimized if it loses focus while fullscreen. (@MV10)
API: Added missing enums to `GetPName`. (@BoyBaykiller)
FIX: Fixed an issue where creating a `NativeWindow` on wayland would freeze in the constructor. (@Th3Dilli)
BREAKING: Re-implemented `Box2/3.Inflate` to work like `System.Drawing.Rectangle.Inflate`. The old behaviour can be found using `Box2/3.Extend`, as the previous obsoletion message stated. (@MV10, @NogginBops)
Add example of how to implement `IBindingsContext` in the documentation comments on `IBindingsContext`. (@utkumaden)
Internal changes to make the build system simpler and easier to modify. (@NogginBops)
Internal changes from `Math` to `MathF` where appropriate. (@MV10)
