plz send me a mini project for cg
OpenGL
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.
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.
OpenGL is an API provided by your graphics card driver. To update it, you need to download newer drivers for your graphics card. If this does not resolve your issue, you will need to purchase a new graphics card to use the application.
Some of the topics for mini projects using computer graphics with OpenGL are to implement a working model of the solar system showing all planets as they rotate on their individual axis and around the sun, concocting a 'rube goldberg' type machine and showing the workings, or just a 'steam-punk' type of machinery with all the gears interacting.
Google Earth requires a 3D capable graphics card with DirectX9 or OpenGL with 64MB of VRAM. Google Earth simply won't work without a graphics card.
JOGL is an OpenGL code for Java, it's used to support 3d graphics and other projects produced and coded in the Java code language for general consumer use..
Changed your graphics setting to OpenGL or D3D
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 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 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.
