    Re: Official feedback on OpenGL 3.1 thread

    Couldn't the driver reconfigure itself / load the code for legacy APIs only after some call to them was made?

    Regardless, I like being explicit in my code, and I would prefer what you've...

    Re: OpenGL 3 Updates

    I don't think there is any reason to be so negative. The ARB and its members are not incompetent, and if I were a member of the ARB I'd be rather upset the suggestion.

    "Storage" as you put it affects the definition of operations over matrices.

    You are enabling GL_DEPTH_TEST but you're not asking for a depth buffer when you call glutInitDisplayMode. You're also not clearing the depth buffer when you call glClear.
