Computer Graphics and its Types

What is computer graphics?

computer graphics is an art in which images, lines, and charts, etc., are created by programming in a computer.

A simple image or picture can say thousands of sentences.

In other words, making pictures in computer screens is computer graphics.

computer graphics is made up of very abstract pixels. A pixel is the smallest unit of graphics seen on a computer screen.

The term computer graphics was first used by Verne Hudson and william fetter in the 1960s.

When we draw a picture in a paper, we use pencil, color, and eraser in it. If something goes wrong while making a picture in paper, we erase it with rubber, then it gets stained or blackened and if the color looks wrong then we have to make another picture in another paper which is a difficult and difficult Work.

To avoid this problem and to make a picture easily, we use computer graphics. By which we can draw any picture. Any change in it like rotate, swap color, shift picture etc. can do many abstract work.

Computer graphics are used in painting, desktop publishing, autocad for building architecture, making games, making movies, forecasting weather in science, etc.
