1.Computer Aided Design(CAD)
in CAD ,interactive graphic is used to design components and system of mechanical ,electrical, electromechanical and electronic devices including structure such as buildings ,automobile bodies, airplane ,VLSL chips ,optical system and telephone and computer.
->The emphasis is on interacting with a computer-based model of the component or system being designed in order to test , for example its structural, electrical or thermal properties.
->The model is interpreted by simulator that feeds back the behavior of system to the user for further interactive design and test cycles.
->Some mechanical part manufactured by describing how the surface are to be formed with machine tools.
2. Presentation Graphic
->A presentation Graphics are used to provide illustration for report or to generate transparencies for use with graphics.
->Presentation Graphic commonly used to summarize financial, statistical ,mathematical, scientific and economic data for research report ,managerial reports and other of reports.
->Typical example are bar charts ,Line graphs ,surface graph, pie charts and other displays showing relationship between multiple variable.
3.Computer Art
-> computer Graphic is used to generate arts.
->They are widely used in both fine art and commercial art application.
->Fine arts is drawn by artist hand this kind of arts is perfect to the artist skill.
->Artist use variety of computer methods including special purpose hardware ,artist paints brush program, other paint package ,specially developed software.
->computer art is not as realistic as fine arts.
4.Education and Training
->Computer Graphics is used in education and training for making it more effective and more illustrative.
->For example , if teacher is to teach bonding of molecules or electron jump form higher energy state to lower energy state or the structure of gene. Then he can demonstrate these concepts using computer graphics software or presentation.
-> Another example could be taken for surgery. A student can learn surgery using data gloves and realistic computer graphics. This way the cost of education will be low and risk of human life as well.
5.Entertainment
->Computer Graphics methods are new commonly used in making motion pictures, music video and tv shows.
->Images are drawn in wire-frame form and will be shaded with rendering methods to produce solid surface.
->Music videos use graphic in several ways. Graphics objects can be combined with the line action.
->Computer Graphics are used to introduce virtual characters to movies.
6.Images Processing
->Image can be created using simple point program or can be fed into computer by scanning the image.
->These picture/image need to be changed to improve the quality.
->Form image/pattern recognition system ,images need to be changed in specified format so that the system can recognize the meaning of the picture.
->For example scanners with OCR features must have letters similar to standard font set.
7.Graphical User Interface
->GUIs have become key factors for the success of the software or operating system.
->GUI uses graphical objects called gizmos represent certain object or process involved in human computer communication for virtual purpose.
->Lots of aesthetics(colors) and psychological analysis have been done to create user friendly GUI.
->The most popular GUI is windows based GUI. The GUI creators are putting having emphasis on 3D GUI creation.
