Introduction to Computer Graphics:

Today there are very few aspects of our lives not affected by computers. Practically every cash or monetary transaction that takes place daily involves a computer. In many cases, the same is true of computer graphics. Whether you see them on television, in newspapers, in weather reports or while at the doctor’s surgery, computer images are all around you.

 “A picture is worth a thousand words” is a well-known saying and highlights the advantages and benefits of the visual presentation of our data. We are able to obtain a comprehensive overall view of our data and also study features and areas of particular interest. 

A well-chosen graph is able to transform a complex table of numbers into meaningful results. You know that such graphs are used to illustrate papers, reports and thesis, as well as providing the basis for presentation material in the form of slides and overhead transparencies. A range of tools and facilities are available to enable users to visualize their data, and this document provides a brief summary and overview.

 Computer graphics can be used in many disciplines. Charting, Presentations, Drawing, Painting and Design, Image Processing and Scientific Visualization are some among them.

Graphics is defined as any sketch or a drawing or a special network that pictorially represents some meaningful information. Computer Graphics is used where a set of image needs to be manipulated or the creation of the image in the form of pixels and is drawn on the computer. Computer Graphics can be used in digital photography, film,entertainment, electronic gadgets and all other core technologies which are required. It is a vast subject and area in the field of computer science. Computer Graphics can be used in UI design, rendering, geometric object, animation and many more.In most area, computer graphics is an abbreviation of CG. There are several tools used for implementation of Computer Graphics. The basic is the <graphics.h> header file in Turbo-C, Unity for advanced and even OpenGL can be used for it’s Implementation. It was invented in 1960 by great researchers Verne Hudson and William Fetter from Boeing. 

What is  Computer Graphics:

Computer graphics is the technology that deals with design and picture on computers. The meaning of graphics is image or visua; representation of object. It is the computer device or program that makes the computer capable of displaying pictures. It is the sub field of computer science. There are two kinds of computer graphics:raster and vector. Raster images are called bitmap image.

What is computer graphics and its types?

Basic. Two Kinds of Computer Graphics. There are two kinds of computer graphics - raster (composed of pixels) and vector (composed of paths). Raster images are more commonly called bitmap images. A bitmap image uses a grid of individual pixels where each pixel can be a different color or shade.

What is the meaning of graphics?

A graphic is an image or visual representation of an object. Therefore, computer graphics are simply images displayed on a computer screen. Graphics are often contrasted with text, which is comprised of characters, such as numbers and letters, rather than images.

What is meant by digital graphics?

A digital graphic is an electronic image that can be used for a variety of different things, however the image does not always have to be used on electronic devices as it can be printed and used. Some examples of a digital graphic are magazines, posters, logos etc
