Questions tagged [opentk]

The Open Toolkit is an advanced, low-level C# library that wraps OpenGL, OpenCL and OpenAL. It is suitable for games, scientific applications and any other project that requires 3d graphics, audio or compute functionality.

The opentk toolkit wraps OpenGL, OpenCL, OpenAL to C#. This is done using types aiming to make development less error-prone.

The project ships with additional code for instance to render OpenGL graphics on a System.Windows.Forms.Form dialog or control together with loaders for various format.

The project is licensed under the MIT/X11 license.
