Computer graphics are pictures and movies created using computers, usually referring to image data generated with graphical hardware and software. Graphics are used to inform, illustrate, and entertain, and include representations of data. There are two main types: two-dimensional graphics like digital images and pixel art; and three-dimensional graphics that use 3D representations stored in computers. Computer graphics have many applications including television, newspapers, and medical imaging. Graphics software enables manipulating visual images on a computer and includes programs for animation, modeling, and photo editing.

2. What is Graphics?
2
Graphics means:
 Clear lifelike or vividly realistic description.
 vividly or plainly shown or described
E.g. autographs are images or designs on some
surface, such as a visual wall, canvas, screen,
paper, or stone

3. Purpose of Graphics
3
Their purpose is
 to inform,
 to illustrate,
&
 to entertain.
It includes pictorial representation of data.
Images that are generated by a computer are
called computer graphics

4. What are Computer Graphics?
4
Computer graphics are pictures and movies
created using computers, usually referring
to image data created by a computer
specifically
with help from specialized graphical hardware
and software.
Another name for this field is
Computer Generated Imagery ,
simply said as CGI

5. Computer Graphics?
5
The term computer graphics describes "almost
everything on computers that is not text or sound".
It refers to several different things:
 the representation and
manipulation of image
data by a computer
 the various technologies used to
create and manipulate images.

6. Applications of computer
graphics
6
Computer graphics is widespread today.
Computer imagery is found on
 Television
 Newspapers ,
 Weather Reports
&
 all kinds of Medical Investigation and Surgical
Procedures.

7. Types of Computer Graphics
7
Two-dimensional
 2D computer graphics are the computer-based
generation of digital images—mostly from models,
such as digital image, and by techniques specific to
them.
Pixel art
 A large form of digital art being pixel art is created
through the use of raster graphics software, where
images are edited on the pixel level.

8. Types of Computer Graphics
8
Sprite graphics:
 A sprite is a two-dimensional image or animation
that is integrated into a larger scene.

9. 9
Vector graphics:
 Vector graphics is the creation of digital
images through a sequence of commands or
mathematical statements that place lines and
shapes in a given two-dimensional or three-
dimensional space.

10. Types of Computer Graphics
10
Three-dimensional
3D graphics compared to 2D graphics are graphics that
use a three-dimensional representation of geometric data.
 For the purpose of performance this is stored in the
computer.
 This includes images that may be for later display or for
real-time viewing.
Computer animation
Computer animation is the art of creating moving images
via the use of computers. It is a sub-field of computer
graphics and animation.
