Computer graphics are graphics created using computers and, more generally, the representation and manipulation of pictorial data by a computer.
The term computer graphics includes almost everything on computers that is not text or sound.
Today nearly all computers use some graphics and users expect to control their computer through icons and pictures rather than just by typing [1].
The term Computer Graphics has several meanings:The representation and manipulation of pictorial data by a computer.
The various technologies used to create and manipulate such pictorial data.
The images so produced, * the sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content.
Today, computers and computer-generated images touch many aspects of our daily life. Computer imagery is found on television, in newspapers, in weather reports, and during surgical procedures. A well-constructed graph can present complex statistics in a form that is easier to understand and interpret.
Such graphs are used to illustrate papers, reports, thesis, and other presentation material. A range of tools and facilities are available to enable users to visualize their data, and computer graphics are used in many disciplines.
Computer Graphics systems could be active or passive. In both cases, the input to the system is the scene description and output is a static or animated scene to be displayed. In case of active systems, the user controls the display with the help of a GUI, using an input device. Computer Graphics is now-a-days, a significant component of almost all systems and applications of computers in every field of life.
Computer graphics techniques provide the primary means by which we are able to view the results of wide ranging computational processes. Additionally, these techniques play a pivotal role in our interaction with the digital word. As indicated in Figure 1.1, computer graphics underpins the
modern human-computer interface. Here, we indicate a collection of hardware and software (which we Zero to Mastery in Computer Graphics
loosely refer to as ‘graphics elements’) that provide a vital interface between underlying digital data and the human operator. These elements support the synthesis and depiction of pictorial imagery that is presented to the complex human visual system.
