Graphics programming, demoscene and book reviews
If you want to open an OpenGL window, most of tutorials and books will tell you to use GLFW, FreeGLUT or SDL framework. Just call glfwInit(), glfwCreateWindow() and you are done. However, if you need to write a size-limited executable or simply don’t want to create another dependency, you have to take care of this by yourself. This is how to do it “the hard way”.
