OpenTK is a fast, low-level C binding for OpenGL, OpenGL ES, OpenAL, and OpenCL. It runs on Windows, Linux, macOS, BSD, and SteamOS, and can be used standalone or integrated with existing GUI frameworks such as Windows.Forms, WPF, GTK, Qt, and VTK. The library provides cross-platform 3D graphics, audio, compute, and haptics capabilities, along with a GLFW-based windowing and input system supporting keyboard, mouse, and joystick. It also includes a performant linear algebra library for math operations and offers inline documentation with strong typing. OpenTK supports OpenGL 4.6 and OpenGL ES 3.2, making it suitable for modern graphics applications. Designed for building games, simulations, scientific applications, and custom renderers, OpenTK enables developers to write code once and run it everywhere with .NET Core and .NET 6 support. The library is MIT licensed and available as a NuGet package, with community tutorials available for learning modern OpenGL.
