Computer Graphics is a sub field in computer science and they are visual presentations on some surface, such as a wall, canvas, computer screen, paper, etc. Examples are photographs, drawings, maps, numbers, or other images. Graphics often combine text, color, sound, and animation.

Computer graphic defination and computer graphic types and computer graphic application

Definition Of Computer Graphics

Computer Graphics are graphics created with the help of computers and more generally the representation and manipulation of image data by a computer. It refers to any computer device or program that makes a computer capable of displaying and manipulating pictures. The term also refers to the images themselves.

The term computer graphics has several meanings:-

The manipulation of pictorial data by computer.

Many technologies used to create and manipulate such pictorial data.

The image was also produced.

Important Point About Computer Graphics

Computer graphic also help for computers easier to interact with, and better for understand and interpreting many types of data.
It play vital role in the field of movies and video game industry.
Images are produced with the help of optical devices; such as cameras, mirrors, lenses, telescopes, microscopes, etc.
The image is then digitized.
Digitized imagery can be categorized into several different types: 2D, 3D, 4D, and animated graphics.
3D computer graphics have become more common, but 2D computer graphics are still widely used.
In computer graphics design mainly required CPU and large amount of memory.
In graphics applications, for example, computer animation systems require more computing power than is available on personal computers and will run only on powerful workstations or specially designed graphics computers.

2D and 3D Computer Graphics

2D Computer Graphics

In 2D computer Graphics are the generations of digital images using a computer that have mostly two - dimensions models (x, y).
2D graphics started in 1950s.
This mainly used in applications that were originally developed upon traditional printing and drawing technologies.

3D Computer Graphics :

In contrast to 2D computer graphics are graphics that use three - dimensional representation of geometric data that is stored in computer for the purpose of performing calculations and rendering 2D images.
Such images are used for real time viewing as they have 3 axis ( x, y, z).

Types Of Computer Graphics

It divided into two parts. This two parts are following :-

Interactive Graphics

In interactive graphics the user may interact with the graphics and with the programs generating them example: can make any change in image show on the screen.

Advantages Of Interactive Computer Graphics

It produce high quality images.
The interactive computer graphics results are more reliable.
It's cost is lower.
It provide large productivity.
Lower analysis.

Working Of Interactive Graphics Display

Interactive graphics display mainly consist three main components :

Frame Buffer Or Digital Memory
Monitor
Display Controller

The image is stored in frame buffer in the form binary numbers which represents as a array of picture elements or pixels. For example, where you want to store only black and white images, so you can represents black pixels by 1's and white pixels by 0's in the frame buffer.

Passive Graphics

In passive computer graphics the user has no control over the image example can not make any change in image show on the screen.

Application Of Computer Graphics

Computer graphics is an essential topic in the field of computer science. Computer graphics provide vast applications in different fields.

These applications can be:

Computational Biology
Computational Physics
Computer Aided Design
Computer Simulation
Digital art
Education
Graphic Design
Info - Graphics
Information Visualization
Rational Drug Design
Scientific Visualization
Video Games
Virtual Reality
Web Design

In this post discuss about the computer graphics. I hope you have learned reading to this post. If you like this post then share with your friends and you can comment any of your doubts and i will replay then at the earliest.

Keep smile all the time.
