OpenTK 4.9.4

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: 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

BREAKING: Made Matrix3/4.CreateFromQuaternion and Matrix3x4/4x3.CreateFromQuaternion produce idential results for non-normalized quaternions. (@NogginBops) API: Add explicit casts to and from System.Numerics types. (@DamienIsPoggers, @NogginBops) API: Added VectorN.Round/Ceiling/Floor/Truncate element-wise functions. (@NogginBops) API: Add ShaderStorageBufferBinding, ShaderStorageBufferStart, and ShaderStorageBufferSize to GetIndexedPName. (@NogginBops) API: Add MathHelper.RadToDeg(d) and MathHelper.DegToRad(d) constants for conversion between radians and degrees. (@DamienIsPoggers) API: Add support for the ALC_SOFT_loopback OpenAL extension through OpenTK.Audio.OpenAL.ALC.Loopback. (@NogginBops) FIX: Update OpenTK.redist.glfw to GLFW 3.4 so that the GLFW 3.4 apis work properly. (@NogginBops) FIX: Optimized VectorN.this[int i] and MatrixN.this[int row, int col] indexers. (@NogginBops) FIX: Made Color4.FromHsv and Color4.FromHsl work correctly when hue is 1. (@NogginBops) FIX: Updated OpenAL DllNotFoundException exception message to mention having to install OpenAL. (@NogginBops) FIX: The documentation for NativeWindowSettings.RenderFrequency now correctly refers to UpdateFrequency instead of UpdateFrame. (@NogginBops)
