Opengl Graphics Driver 2.0 Download Install Update
If you are visiting this page because a game or software uses the OpenGL API, you need to install the appropriate graphic driver which enables usage of the functionality provided. To program using the OpenGL API, you need the driver and the development package depends on platform and programming language.
More platform-specific details are described in the sections below. However, you will need to ensure that you have downloaded and installed a recent driver for your graphics hardware. Some sites also distribute beta versions of graphics drivers, which may give you access to bug fixes or new functionality before an official driver release from the manufacturer:.
Without drivers, you will default to a software version of OpenGL 1. None of these options are particularly fast, so installing drivers is always a good idea. See this wiki link for details:. Graphics on Linux is almost exclusively implemented using the X windows system. In addition the Direct Rendering Infrastructure DRI is a driver framework that allows drivers to be written and interoperate within a standard framework to easily support hardware acceleration, the DRI is included in of XFree86 4.
Popular Linux distros come with XOrg now. Vendors have different approaches to drivers on Linux, some support Open Source efforts using the DRI, and others support closed source frameworks but all methods support the standard ABI that will allow correctly written OpenGL applications to run on Linux.
For developers, a default installation of macOS does not include any OpenGL headers, nor does it include other necessary development tools. These are installed by a separate developer tools package called Xcode. The first step is to pick your language. Some languages have multiple sets of OpenGL bindings, none of them being official.
Some come pre-installed, but others have separate downloads. Under Windows, you need to statically link to a library called OpenGL The "32" part is meaningless.
Visual Studio, and most Windows compilers, come with this library. Before you can actually use OpenGL in a program, you must first initialize it. Because OpenGL is platform-independent, there is not a standard way to initialize OpenGL; each platform handles it differently. There are two phases of OpenGL initialization. The first phase is the creation of an OpenGL context ; the second phase is to load all of the necessary functions to use OpenGL.
Creating one is very platform-specific, as well as language-binding specific. These libraries create a window, attach an OpenGL context to this window, and manage basic input for that window. Once you are comfortable with OpenGL, you can then start learning how to do this manually. For most libraries you are familiar with, you simply include a header file, make sure a library is linked into your project or makefile, and it all works.
OpenGL doesn't work that way. For reasons that are ultimately irrelevant to this discussion, you must manually load functions via a platform-specific API call. This boilerplate work is done with various OpenGL loading libraries ; these make this process smooth.
You are strongly advised to use one. If you want to do it manually however, there is a guide as to how to load functions manually. You still should use an extension loader. OpenGL is a rendering library. What OpenGL does not do is retain information about an "object". All OpenGL sees is a ball of triangles and a bag of state with which to render them. It does not remember that you drew a line in one location and a sphere in another.
Because of that, the general way to use OpenGL is to draw everything you need to draw, then show this image with a platform-dependent buffer swapping command. If you need to update the image, you draw everything again, even if you only need to update part of the image. If you want to animate objects moving on the screen, you need a loop that constantly clears and redraws the screen.
There are techniques for only updating a portion of the screen. And you can use OpenGL with these techniques. But OpenGL itself doesn't do it internally; you must remember where you drew everything. You must figure out what needs updating and clear only that part of the screen. There are many tutorials and other materials available for learning how to use OpenGL, both on this wiki and online.
These are programs that you install and run, and they give you information specific to the OpenGL API your system implements, like the version offered by your system, the vendor, the renderer, the extension list, supported viewport size, line size, point size, plus many other details.
Some might include a benchmark. Some are standalone benchmarks. Retrieved from " http: Navigation menu Personal tools Create account Log in. Views Read View source View history. This page was last edited on 8 September , at

How To: Check the graphics card type and OpenGL version
OpenGL drivers are usually installed together with the rest of the graphics driver and support software such as DirectX.
