Computer Graphics Introduction

Computer graphics refers to the creation, manipulation, and display of images using computers. It involves the use of software and hardware to generate and process images, videos, and animations. Computer graphics are used in a wide range of fields, including entertainment, advertising, design, education, and scientific visualization.

Computer graphics can be divided into two main categories: raster graphics and vector graphics. Raster graphics are made up of pixels or dots, which are arranged in a grid to create an image. Common examples of raster graphics include digital photographs and scanned images. Vector graphics, on the other hand, are created using mathematical equations to define shapes and lines. This allows them to be scaled without losing quality. Examples of vector graphics include logos and illustrations.

Computer graphics software is used to create and manipulate images. Popular software includes Adobe Photoshop for raster graphics and Adobe Illustrator for vector graphics. 3D modeling software like Autodesk 3ds Max and Blender are used to create three-dimensional objects and environments for video games, movies, and animations.

In addition to software, computer graphics also rely on hardware like graphics cards and monitors. Graphics cards are specialized computer components that handle the processing of visual data, while monitors display the resulting images. The quality and capabilities of these hardware components can have a significant impact on the quality and performance of computer graphics.
