OpenTK 4.0.1

The Open Toolkit is set of fast, low-level C# bindings for OpenGL, OpenGL ES and OpenAL. 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: https://opentk.net/learn/index.html Sample projects that accompany the tutorial can be found here: https://github.com/opentk/LearnOpenTK We have a very active discord server, if you need help, want to help, or are just curious, come join us! https://discord.gg/6HqD48s
