Computer Graphics: What is it?

     Put simply, computer graphics is the representation of an image using graphics hardware and software on computers. Anything that is not text or sound from a computer screen is generally considered to be computer graphics. The image is stored as data, and when a user wishes to view it, the computer converts it to an understandable form using its own graphics capabilities. There are many styles of computer graphics, and they can be animated as well.

      As depicted above, computer graphics can involve smooth images or pixel art. Movies that you view on a computer is stored as data that the computer deciphers into a series of images that you can understand. A picture on a computer is stored as a chunk of data and when you open it the computer draws it for you using the data as a guideline. 3D figures are also part of computer graphics and may use animation as well. All of these use similar techniques of storing the image information in a file and using graphics hardware and software to draw the image using the data stored when a user wishes to access it. Images can then be manipulated and changed using programs like Adobe Photoshop if the user wishes to do so. Computer graphics is constantly getting better and eventually, we will probably have images and movies that parallel real life, made entirely using computer graphics imaging.
