What is GLUT? How is it different from OpenGL?
Because OpenGL doesn’t provide routines for interfacing with a windowing system or input devices, an application must use a variety of other platform-specific routines for this purpose. The result is nonportable code. Furthermore, these platform-specific routines tend to be full-featured, which complicates construction of small programs and simple demos. GLUT is a library that addresses these issues by providing a platform-independent interface to window management, menus, and input devices in a simple and elegant manner. Using GLUT comes at the price of some flexibility. A large amount of information on GLUT is at the GLUT FAQ.
