What Is Computer Graphics?

The term Graphics mean is Graphical Tricks. All image or picture is actually a graph and when various mathematical tricks are utilized to manipulate several change in its properties like motion, size, shape and so on, through the assist of computers after that, the representation is nothing although computer graphics, consequently we can say that "Computer Graphics (CG) is the place of visual computing, where one utilizes computers both to make visual images synthetically and to incorporate or change visual and spatial information sampled from the true world." Or "CG is the pictorial representation manipulation of data by a computer" Or "CG refers to any drawing, sketch, special artwork or the other material generated along with the facilitate of computer to pictorially depict an object or a method or otherwise convey information, like a supplement to or in place of written explanations".

CG is a complicated and diversified field. A Picture is a fundamental cohesive model in CG. Each picture comprises points termed as pixels or Picture-element. If we judge a complicated picture, then complicated database for pixels are considered, thus, complicated algorithm are needed to access them. These complicated databases comprise data organized in different data structures as ring structures, B-tree etc.

In our previous courses CS-60, we had learned mathematical tricks to do jugglery along with the graphs which resulted from different functions; here let us learn how to juggle along with graphics by utilizing computers. There are several algorithms that can be materialized to generate graphical effects on the screen through some graphical tools based on diverse languages which are available in the market.

Computer graphics can be generally divided into the subsequent classes:

  • Business Graphics or the broader type of Presentation Graphics that refers to graphics, as bar-charts also termed as histograms, pie-charts, pictograms that is: scaled symbols and x-y charts and so on, used to represent quantitative information to inform and convince the audience.
  • Scientific Graphics, as x-y plots, contour plots, curve-fitting, system or program flowcharts and so on.
  • Scaled Drawings, as architectural representations, drawings of bridges, buildings and machines.
  • Cartoons and artwork, as well as advertisements.
  • Graphics User Interfaces (GUIs) that are the images which appear on approximately all computer screens these days, designed to assist the user utilize the software without consisting to refer to manuals or read many text on the monitor.

We will converse the different classes of computer graphics mentioned over in the following sections of this section.

The most familiar and helpful class of computer graphics involves video games and movies. Movies usually require graphics which are indistinguishable from physical reality, while video games require graphics that can be generated rapidly sufficient to be perceived as smooth motion. These two requirements are incompatible, although they define two-ways of communications between computations and users. In video games, the subject issue of computations is usually characters chasing and shooting at any one. A more familiar utilization of computer graphics exists for interacting along with scientific computations apart from games and movies. This familiarization of the utilization of computer graphics has affected our life, by simulations, virtual reality, animation; we can extend the scope of analysis, education, entertainment etc. Consequently, in global terms Computer graphics can be categorized in two manners:

Interactive Computer Graphics that is interactively utilized by user for instant: games.

Passive Computer Graphic that has no option for users to interact or utilizes computer graphics for example: movies. We will converse details about this category of graphic systems in Block 4 further.
