Let’s do itįirst, make sure you have glext.h and wglext.h from the Khronos’ OpenGL registry. Luckily, this can be solved by creating a dummy window and context with old functions, getting new function pointers and creating window and context in the desired format. To create a rendering context using them, you have to get their function pointers, and for this, you need a rendering context. Both of them accepts lists of attributes, so they can support any number of options. To remedy this, new functions have been created, namely wglChoosePixelFormatARB() and wglCreateContextAttribsARB(). Using the later one, you cannot ask for specific OpenGL profile or version. For example, the first one uses fixed PIXELFORMATDESCRIPTOR structure and there is no field you could set to indicate that you want to request multisampling, sRGB format or floating-point framebuffer support. The problem with old ChoosePixelFormat() and wglCreateContext() is that they are not extensible. Load new OpenGL functions with wglGetProcAddress() and you are ready to use them. Then you can create Rendering Context with wglCreateContext() and set it as current with wglMakeCurrent(). Next, pick a hardware accelerated pixel format with ChoosePixelFormat() and associate it with Device Context using SetPixelFormat().

You should start with creating a window with CreateWindow() and use its handle to get Device Context with GetDC(). To create a context, you must first create a contextīefore getting functions pointers or issuing OpenGL commands, you have to create an OpenGL rendering context.

There are OpenGL loading libraries such as GLEW or G元W to save you the trouble.

This can be done with wglGetProcAddress() function from version 1.1 of opengl32.dll library. To gain access to newer functions, you must load their pointers manually at runtime. To use modern functions, you also need to add glext.h and wglext.h from the Khronos’ OpenGL registry. Windows SDK provides gl.h for version 1.1.

You have to install graphics card drivers from NVIDIA, AMD or Intel to enable access to newer version’s features. In 2006, members of the Khronos Group (like NVIDIA and AMD) announced that they will support OpenGL using installable client drivers (ICD).Īs a result of these API wars, Windows installations include only version 1.1 of OpenGL library. In 2003, Microsoft left the OpenGL Architecture Review Board, and in 2005 at SIGGRAPH they suggested that they will remove support for OpenGL from Windows Vista, keeping just an emulation layer on top of DirectX only for back-compatibility with Windows XP software. John’s responses and later Microsoft’s campaign against OpenGL in favour to their proprietary library, things got a bit complicated. “It’s complicated”ĭue to various historical events like John Carmack’s letter that favoured OpenGL over Direct3D, Alex St. Well, let me tell you something my friend: “One does not simply initialize OpenGL”. Normally, as with most of the libraries, you would #include, add opengl32.lib to linker dependencies and just use all the features of the modern OpenGL in your program, maybe with some kind of additional glInit() call. 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. Just call glfwInit(), glfwCreateWindow() and you are done. If you want to open an OpenGL window, most of tutorials and books will tell you to use GLFW, FreeGLUT or SDL framework.
