Computer graphics deals with computerized image synthesis and includes everything on computers that is not text or sound. It has grown from a small specialized field to include the creation and manipulation of models and images. The popularization of personal computers with bitmap graphics capabilities in the 1980s led to an explosion of graphics applications for tasks like spreadsheets, presentations, computer art, entertainment, education, visualization, and image processing. Interactive computer graphics allow two-way communication between users and computers for applications like engineering design.
International Journal of Computer Graphics & Animation (IJCGA)ijcga
Computer graphics and animation have has become a key technology in determining future research and development activities in many academic and industrial branches. The aim of this journal is to be an international peer-reviewed open access forum for scientific and technical presentations and discus the latest advances in Computer graphics and animation.

This is my First PPT for the basics in CAD and
i will share PPT on NX UG design software. I would love to share one PPT for each week. Thank you ONE & ALL
A graphics card is a device installed in a computer that consists of a graphics processing unit designed to help process and display images, especially 3D graphics. Graphics cards help take the processing strain off the main processor, and can contain their own memory to take the strain off the system RAM

Computer graphics are pictures and films created using computers. Usually, the term refers to computer-generated image data created with the help of specialized graphical hardware and software. It is a vast and recently developed area of computer science.
1. Computer Graphics
Introduction:
Definition: Computer Graphics is generally
regarded as Computer Science that deals
with the theory & technology for
computerized image synthesis.
In other words we can say, the term
Computer graphics includes almost
everything on computers that is not text or
sound.
2. Today almost every computer can do some
graphics, and people have even come to
expect to control their computer through
icons and pictures rather than just by
typing.
It has grown to include the creation, storage
and manipulation of models and images of
objects.
3. Until the early 1980’s, CG was a small,
specialized field b’coz the hardware was
expensive and there are very few graphics
based application programs..
Then PC with built in raster graphic display
such as Xerox star, apple Macintosh &
IBM PC popularized the use of bitmap
graphics for user and computer interaction.
4. A Bitmap is a 1’s or 0’s representation of the
rectangular array of points on the screen.
Once bitmap graphics become affordable,
an explosion of easy to use & inexpensive
graphics based applications are followed
which allows no. of user to control simple
low cost application programs such as
spreadsheets, word processors & drawing
programs.
5. Application of Computer Graphics
Computer Aided Design
Presentation Graphics
Computer Art
Entertainment
Education And Training
Visualization
Image Processing
6. Types of Graphics
Passive Graphics
In passive graphics, operation
transfers automatically & without operator
intervention. The observer has no control
over the image or we can say there is no
communication between the computer and
user. Familiar e.g of this form is titles
shown on T.V or Video games.
7. Interactive Graphics
Interactive CG involves two
way communication b/w computer and
user.The user maintain the conversation
with the computer.
E.g: The Engineer Designing an integrated
circuit can see on the screen and has the
ability to interact with the computer, the
Engg. can quickly correct a design error.
8. Working :
Application Application Graphics
Model Program System
Application Model: Represents data &objects.
Application Program: it creates, stores info,&
retrieve from AM.
Graphics System: have a series of graphics
output commands
