What is the difference between FreeGLUT vs GLFW?

Question

My university started teaching a course which includes OpenGL programming. They make us use FreeGLUT to create a window and a context for OpenGL, but I found an online cours

Answer 1

FreeGLUT:

• Based on the GLUT API.
• GLUT has been around for about as long as OpenGL itself.
• Many tutorials and examples out there use GLUT.
• Takes care of implementing the event loop and works through callbacks (good for simple stuff, makes things like precisely timed animation loops and low latency input much harder though).

GLFW:

• Designed from scratch with the experiences of other frameworks in mind.
• Gives much finer control over context creation and window attributes.
• GLFW-2 Provides basic threading support functions (thread creation, synchronization). –– removed from GLFW-3
• GLFW-2 Provides basic image file loading support. –– removed from GLFW-3
• Gives very detailed access to input devices.
• Event loop is in control of the programmer which allows for much preciser timing and lower latency.
