My understanding is that OpenGL itself is only library without defining of Framebuffer. So, with only OpenGL library, I can make fragment, but it cannot be drawn on a framebuffer since framebuffer is not defined.
So, GLUT, GLX, or WGL based on Operating System would make it work completely. Right?
If then, what if I want to make a similar one like GLUT/GLX/WGL? How can I get only OpenGL core library without GLUT/GLX/WGL?
Since I am very new to OpenGL, if there is missing point, please guide me correctly.
