cl-opengl is a set of CFFI bindings to OpenGL.

Ada OpenGL binding GLOBE_3D is a free, open-source, real-time 3D Engine written in Ada, based on OpenGL.

Ada OpenGL bindings supports GL & GLU and GLUT.

OpenGLAda is a thick Ada binding for OpenGL and GLFW.It offers complete independence from network protocols and topologies.ДЄll OpenGL applications produce consistent visual display results on any OpenGL API-compliant hardware, regardless of operating system or windowing system. To answer the question 'Which one should I use?' - in any case you want to use GLEW (or an alternative, but GLEW works fine), but you most likely want to use both GLEW and GLFW since it makes your life easier.OpenGL is supported on every major operating system, it works with every major windowing system, and it is callable from most programming languages. without having to deal with that nasty stuff. So basically, with GLEW, you call one function to init everything, and then you can very comfortably check what you have available, and use it right away. This is a lot of nasty and error-prone work even for someone reasonably experienced, lest a beginner. Then you must set up a lot of function pointers and initialize them. Instead, after creating a context (GL FW will do that for you!) you need to query your context for the supported version and for supported extensions that you may wish to use. That is, you cannot just link with opengl32.dll and expect that everything will magically work for OpenGL 3.0 or OpenGL 4.4. Additionally, all versions after 1.2 technically work as-if extensions.

In addition to the base functionality, you can use extensions, if they are supported (there are well over 300 extensions, and the average graphics card driver supports well over a hundred). Instead, OpenGL is a somewhat blurry 'everything at the same time, and none' and built in an extendable and heavily extended manner, which is not at all obvious or intuitive to a beginner.

What does that mean? Unlike another well-known graphics API from Microsoft, OpenGL does not come as a set of distinct, entirely different, incompatible versions with different libraries which on the other hand have exactly defined functionality and specs. GLEW on the other hand handles the loading of extensions ('GL Extension Wrangler').

You still write GL code to do the drawing, though. In addition, GLFW comes with a set of useful utility functions. All you need to do is write handlers for that, the logic behind it is already written. Rather than deciding what to do when, you call some initialization functions and tell the framework more or less what you expect, and then the framework calls you back at the appropriate times (for example when the user presses a key or moves the mouse, resizes the window). That is, it enforces a kind of structure on your program. In summary, GLFW is what its name says ('GL Frame Work'), a framework. GLFW and freeglut are alternative for us according to our need we can choose any one but GLEW is different from them which is used for run time loading of the OpenGL API.

OpenGL does not handle window creation or input, so we have to use these library for handling window, keyboard, mouse, joysticks, input and other purpose. GLFW or freeglut will allow us to create a window, and receive mouse and keyboard input in a cross-platform way. GLEW will handle the run time loading of the OpenGL API.About GLEW see here But in modern OpenGL, the API functions are determined at run time, not compile time. The OpenGL Extension Wrangler (GLEW) is used to access the modern OpenGL API functions(version 3.2 up to latest version).If we use an ancient version of OpenGL then we can access the OpenGL functions simply including as #include. Glew and glfw are not mutually exclusive as their purpose is different. I'm a directX guy but touched a but of ogl too.
