As such, OpenGL has many language bindings, some of the most noteworthy being the JavaScript binding WebGL (API, based on OpenGL ES 2.0, for 3D rendering from within a web browser) the C bindings WGL, GLX and CGL the C binding provided by iOS and the Java and C bindings provided by Android. Although the function definitions are superficially similar to those of the programming language C, they are language-independent. The API is defined as a set of functions which may be called by the client program, alongside a set of named integer constants (for example, the constant GL_TEXTURE_2D, which corresponds to the decimal number 3553).
Although it is possible for the API to be implemented entirely in software, it is designed to be implemented mostly or entirely in hardware. The OpenGL specification describes an abstract API for drawing 2D and 3D graphics. Īn illustration of the graphics pipeline process Since 2006, OpenGL has been managed by the non-profit technology consortium Khronos Group. (SGI) began developing OpenGL in 1991 and released it on Japplications use it extensively in the fields of computer-aided design (CAD), virtual reality, scientific visualization, information visualization, flight simulation, and video games. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering. OpenGL ( Open Graphics Library ) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics.

Since this is a tedious process there are OpenGL extension loader wrapper libraries, like GLEW (available at ) which package up the extension headers and some library code to do the whole loading thing with just a single command. But since there's no change in the ABI, the actual functions do not come as part of a library but must be loaded at runtime using wglGetProcAddress for each function. That's where extension headers come into play. However newer versions of OpenGL require additional tokens and functions to be defined. In your case you'll find the OpenGL base headers being preinstalled with the default installation of Visual-C++. OpenGL has been included into the ABI (Application Binary Interface) of the major operating systems, including Windows, and hence the standard headers ship with compilers targeted at this system. This is different from DirectX where you need a special SDK.

A OpenGL-3 class GPU can not do OpenGL-4 (but a OpenGL-4 can do OpenGL-3 of course).įor all practical means there's nothing you need to download or to install to get working with OpenGL. The major OpenGL version designates the hardware class. That's also what ultimately determines which version of OpenGL you can use: The GPU on the system the program is executed on. The actual OpenGL implementation ships as part of your GPU's driver.
But there are no library downloads there because, well, OpenGL is not a library. What you can download at are just the specification documents and reference C include headers.
OpenGL is not a library, it's an API specification.
