AntTweakBar is a small and easy to use C/C++ library that allows programmers to quickly add a light and intuitive GUI into OpenGL or DirectX based programs to interactively tweak parameters on-screen.
AntTweakBar works with Linux, Windows and OSX, and can be easily integrated with custom windowing system or with existing toolkits. Examples of integration with GLFW, SDL, GLUT, SFML and DirectX are provided.
The AntTweakBar library mainly targets graphical applications that need a quick way to tune parameters (even in fullscreen mode) and see the result in real-time like 3D demos, games, prototypes, inline editors, debug facilities of weightier graphical applications, etc.
good job! really good for glut!
