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.
1. Direct3D is a proprietary API designed by Microsoft Corporation for hardware 3D acceleration on the Windows platform 2. OpenGL is an open standard API that provides a number of functions for the rendering of 2D and 3D graphics and is available on most modern operating systems. If hardware 3D acceleration is present, OpenGL can use it.

You run in opengl (eg. srb2win.exe -opengl) And bring down the conlsole (with ~) then type in 'gr_md2 1' (no quotes) Download MD2s of the SRB2MB.

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).
You could use Torque or direct x.
OpenGL isn't a program, its an API to access features of a graphics card from an application. To use OpenGL programs, you either need a driver for your video card that supports OpenGL, or the applications needs to be compiled with support for Mesa 3D, a software renderer.
OpenGL is a graphics specification thus any application that makes use of the specification will primarily make use of an OpenGL implementation library. You will also need a graphics card driver that supports OpenGL. Mac and Unix/Linux systems include OpenGL drivers as standard, but PC-based systems do not. You must therefore install the appropriate driver (where required) and also install an OpenGL implementation library. Both ATI and nVidia provide their own proprietary libraries, but you can also use generic libraries (including open source libraries) to provide cross-platform support.

The 6.6KV device will conduct before the 11KV device, quite possibly even in normal operation. Don't use it this way!
