DirectX and OpenGL are collections of application programming interfaces (APIs) for handling tasks related to multimedia, game programming and video, and for writing applications that produce 2D and 3D computer graphics.
Yes. it is up to the video card manufacturer to support OpenGL, however.
OpenGL is not software, it is a specification for cross-platform graphics rendering. All modern graphics cards support the OpenGL specification. In order to program with OpenGL you must first load the OpenGL function pointers. Although you can do this manually it's best to use a library specific to your hardware. Both nVidia and ATI provide their own libraries with tutorials. Remember that OpenGL is not software so there is no official SDK as such. There is no header file named 'opengl' (not officially at least). The OpenGL library headers typically use a gl prefix, such as gl.h, glut.h and glaux.h. The best place to start is by reading the FAQ provided by the official OpenGL website (see related links below). If you're using Windows, you also have the option of using the DirectX API rather than OpenGL. DirectX is not only easier to work with, it also provides support for audio, animation, networking, and so on. OpenGL is purely for graphics rendering but is cross-platform (DirectX only works with Windows).
In order to run a OpenGL program, you must download and install a program called GLDirect. This program allows you to run OpenGL-based games and other applications using your graphics card's DirectX drivers.
In order to run OpenGL on Vista, you must download and install a program called GLDirect. This program allows you to run OpenGL-based games and other applications using your graphics card's DirectX drivers.
You can't replace Direct3d with OpenGL because it's part of your computer. However you can run OpenGL programs or games by downloading and installing a program called GLDirect. This program allows you to run OpenGL-based games and other applications using your graphics card's DirectX drivers.
You can download and install the latest DirectX drivers from Microsoft website. Quickest install is using the DirectX End-User Runtime Web Installer listed in related links below. You can switch Google Earth display mode between OpenGL and DirectX (see related link).
In order to run OpenGL games, you must download and install a program called GLDirect. This program allows you to run OpenGL-based games and other applications using your graphics card's DirectX drivers.
You can play CS 1.6 in OpenGL mode by changing the video mode settings to OpenGL in the options menu or if you're running Vista or Windows 7, you can download and install a program called GLDirect. This program allows you to run OpenGL-based games and other applications using your graphics card's DirectX drivers.
The correct answer is "yes" in the seance that only Windows run DirectX. Other operating systems run OpenGL instead, so therefore. Yes, you can view video without DirectX.However, every Windows system is shipped with some version of DirectX, and it relies on it to display graphics. So therefore, Windows needs DirectX to view video.
Graphics cards typically support DirectX 10, have a number of pixel and vector shaders and also support OpenGL.

Although it's not for personal use, it IS the best single graphics card available. The best place to get a deal on a graphics card like that is newegg.com, or tigerdirect.com.
you can use Direct X or OpenGL to do that but I recommend OpenGL .. it's open source , tons of lessons and examples but Microsoft is working with DirectX ref.s : http://nehe.gamedev.net/ http://www.gamedev.net/
