Computer Graphics: Importance of Computer Graphics
Computer has become a powerful tool for the rapid and economical production of pictures. Computer Graphics remains one the most exciting and rapidly growing fields. Old Chinese saying”One picture is worth of thousand words” can be modified in this computer era into “One picture is worth of many kilobytes of data”. It is natural to expect that graphical communication will often be more convenient when computers are utilized for this purpose. This is true because one must represent objects in two-dimensional and three-dimensional spaces. Computer Graphics has revolutionized almost every computer-based application in science and technology.
Information technology is a trend today. As the volume of information increases, problem of storage arises. As time is money, in the 21st century people doesn’t have the time to read huge number of pages. So this problem is solved by Computer Graphics. . Picture can represent a huge database like bar charts, pie charts etc. suppose, we have to show the performance of some factory related with profit since 1980. One requires large number of pages to store this huge information related with financial, numerical and statistical information. A common man requires a lot of time to understand it. There is an alternative to show or represent this information with the help of graphical tools such as bar chart or pie chart i.e. we can express this data in pictorial forms.
Computer Graphics methods are utilized in Computer Aided Design (CAD) to produce the drawings of certain parts of a machine from any viewing angel. Another area in the field of Computer Aided Manufacturing (CAM) where by employing computer graphics techniques, one may display the manufacturing layout for a given part and trace the path taken by machine tools for a given manufacturing process. Architects can use computer graphics to produce layout of building and utilized them for Computer-Aided-Design (CAD). Virtual reality can take you one more step to further. Your architect can take you to walk in the simulated building to see and feel how accessible are the light switches and selves and so on.
Many people for different domain of applications use interactive graphics. For example, structural engineering use for efficient design of structures on the basis of the analysis of stress in various elements of the structure. From the survey it is evident that in future, engineers, designers etc, will be using computer graphics quite extensively. There is virtually no area in which graphical displays can not be used to some advantage, and so it is not surprising to find the use of computer graphics so widespread. Today, we find Computer Graphics used routinely in such diverse areas such as science, engineering, medicine, business, industry, government, art, entertainment, advertising, education, training, etc.
