GLUT stands for OpenGL Utility Toolkit is a utility library for OpenGL applications to put the platform-dependent details (e.g., creating windows and responding to mouse events and key presses) under one hood, in an easy and portable way.

The OpenGL Utility Toolkit is a kind of library of utilities for OpenGL programs, which primarily perform system-level I/O with the host operating system. Functions performed include window definition, window control, and monitoring of keyboard and mouse input. Routines for drawing a number of geometric primitives are also provided.

The original GLUT has been unsupported for 20 years (see GLUT - The OpenGL Utility Toolkit), but there exists a current, maintained alternative named FreeGLUT.

Tag usage:

The tag can be used for OpenGL Utility Toolkit-related programming problems. The tag can be used for installation related problems of GLUT packages.

GLUT Alternatives for Haskell?

SDL vs GLUT in opengl 3D programming

I'm beginning a series of tutorials on SDL. Before I dig too far, I'd like to know what type of control SDL gives me over GLUT? Also, do either support webcam access (for face tracking or motion detection), or is that best managed through OpenCV?
