Applications of Computer Graphics and Multimedia

Applications of Computer Graphics and Multimedia: Computer graphics and multimedia are right now is the most important part in computer science. Because every day we are dealing with the pictures, images, charts, video, animation etc. computer graphics mainly deals with how they are stored, how they are manipulated and how they are represented on the screen to appear.

Graphics means some visual presentation on a surface. In a computer, this surface is the computer screen where these presentations are normally displayed. Computer Graphics is basically the creation, storage and manipulation of images and models with the help of some graphical hardware and software. Different algorithms and data structures are used to draw pictures using the computer. It is the art of drawing images on a computer using some programming techniques.

On the other hand, multimedia uses computers to present audio, video, animation, interactive features and still images in various ways and these combinations made possible through the advancement of technology. Graphics and multimedia both are interrelated to each other.

Multimedia is an exciting new field for those interested in computers, technology and creative career options. Multimedia can be accessed through computers or electronic devices and integrate the various forms together. For example, multimedia would be combining a website with audio, video or images.

Applications of computer graphics and multimedia:

There are a variety of fields where the applications of computer graphics and multimedia are being used nowadays. This includes medical, engineering, education & training, entertainment, science etc. The applications of computer graphics and multimedia are growing day by day. Let’s see the major applications of computer graphics and multimedia which we are using in our daily life.

CAD (Computer-aided design):

CAD is one of the major applications of computer graphics that occurs at the top of the list. These methods or techniques are routinely used in designing of buildings, space crafts, automobiles, computer textile, computer hardware, watercraft etc.

For some design applications, objects are first displayed in a wire form outline that shows the overall shapes and internal features of the objects. Wire form display also allows the designer to quickly see the effects of the interactive adjustment to design shape. Animations are often used in CAD application. Real-time animation using wire form display on a video monitor is used to form testing the performance of a vehicle or a system. Animations on a virtual reality environment are used to determine how vehicles operators are affected by certain motions.

The object designs are when completed and nearly complete, realistic model and surface rendering are applied to produce displays that mean show the appearance of the final product.

Presentation graphics:

It is used to produce illustrations or repeat to generate 35mm slides used with a projector. Presentation graphics are commonly used to summarize financial, statistical, mathematical and scientific data for recharge report, managerial report and other types of data. Some examples of presentation graphics are bar charts, line charts, surface graph and any type of pictorial representation of data.

Computer art:

Computer graphics methods are widely used in both fine arts and commercial art applications. To use a variety of computational methods including special purpose hardware, artist paint brush programs, other paint packages, specially developed software, CAD packages, desktop publishing software, animation packages that provide facilities for designing objects, shapes and specified object motions.


One of the prime applications of computer graphics and multimedia is that it is used for digital entertainment purpose. Computer graphics techniques are also used in making motion pictures, music videos and television shows. Sometimes the graphics scenes are displayed by this facility and sometimes the actors and line scenes. However, it is seen that music videos nowadays are using graphics in a very complex way.

Graphics objects can be combined with the line actions and images. Processing techniques can be used to produce a transformation of one person or object into another.

Education and training:

Applications of computer graphics and multimedia are often used in educational programs. They are used in the physical, financial and economic system as a computer-generated model. Models of a physical system, psychological system, population trends and equipment such as the colour-coded diagram (CCD) can hold training to understand the operations of the system.


Scientist, engineers, medical person, business analyser and other workers often need to analyse a large amount of information or to study the behaviour of certain processes, numerical simulations,   satellite cameras and other sources of amazingly large data/ files faster than they can be interpreted. Scanning these large set of numbers to determine trends and relationship is an ineffective process. But, if the data converted into visual form then the trend and patterns immediately can be processed more significantly and the process will less complex.

Image processing:

Image processing applies the techniques to modify or interpret the existing pictures such as photographs. The main principle application of image processing is improving the picture quality and machine perception of visual information that used in the images.

To apply image processing techniques a photograph or other pictures are first digitalized onto an image file. Then the digital methods can be applied to be arranged to enhance colour separation or to improve the quality of shading.

Graphical User Interface (GUI):

GUI is one of the vastly used applications of computer graphics and multimedia. A major component of GUI is a window manager that allows a user to display multiple window areas. Each window can contain a different process which contains graphical or non-graphical objects. To make a particular window active, it is to be clicked in that window using an interacting pointing device. Interfaces also display menus and icons for first selection for processing options or any particular person/object.
