Q

raster graphics

A

a type of digital image that uses tiny rectangularpixels, or picture elements, arranged in a grid formation to represent an image.

Because the format can support a wide range of colours and depict subtle graduated tones, it is well suited for displaying continuous-tone images such as photographs or shaded drawings, along with other detailed images.

Q

vector graphics

A

There’s an alternative method of computer graphics that gets around the problems of raster graphics. Instead of building up a picture out of pixels, you draw it a bit like a child would by using simple straight and curved lines calledvectorsor basic shapes (circles, curves, triangles, and so on) known asprimitives.

Q

interactive, non-interavtive

A

classification of computer graphics

21
Q

interactive, non-interavtive

A

classification of computer graphics

22
Q

interactive computer graphics

A

involves a two-way communication between computer and user. Here the observer is given some control over the image by providing him with an input device for example the video game controller of the ping pong game. This helps him to signal his request to the computer.

23
Q

non-interactive

A

aka passive computer graphics. it is the computer graphics in which user does not have any kind of control over the image.

24
Q

passive computer graphics

A

other name of non-interactive

25
Q

computer art

A

application of computer graphics

Using computer graphics we can create fine and commercial art which include animation packages, paint packages. These packages provide facilities for designing object shapes and specifying object motion. Cartoon drawing, paintings, logo design can also be done.

26
Q

computer aided drawing

A

application of computer graphics

Designing of buildings, automobile, aircraft is done with the help of computer aided drawing, this helps in providing minute details to the drawing and producing more accurate and sharp drawings with better specifications.

27
Q

presentation graphics

A

application of computer graphics

For the preparation of reports or summarising the financial, statistical, mathematical, scientific, economic data for research reports, managerial reports, moreover creation of bar graphs, pie charts, time chart, can be done using the tools present in computer graphics.

28
Q

entertainment

A

application of computer graphics

Computer graphics finds a major part of its utility in the movie industry and game industry. Used for creating motion pictures , music video, television shows, cartoon animation films. In the game industry where focus and interactivity are the key players, computer graphics helps in providing such features in the efficient way.
