What is the difference between FreeGLUT vs GLFW?

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 course at lynda.com about OpenGL in which they use GLFW instead of FreeGLUT.

So I want to know which one should I use and what are the differences between the two?

Solution

  • 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.
