Digital Graphics and why it’s an evolution in 21st century

Introduction

A graphic can be described as a medium to present an object visually or through an image. Therefore, computer graphics are considered as simple images which displayed on a computer screen. Graphics are often created in contrast with text, which includes letters and numbers. The images are easier to interpret than the long texts. So, sharing the message with the target audience becomes easier with those graphical works. The images also grab the attention of the viewers easily. As an effect, the use of graphics is also increasing due to the multiple benefits.Our expert from Online Assignment Help will now explain you the evolution of computer graphics and how it can be important.

Evolution of Computer Graphics

Computer graphics are either two or three-dimensional. Computers in the early age were able to support2D monochrome graphics only. It means those graphics wssere black and white. In some cases, the black and green graphics were also found, depending on the type of monitor. With time, advanced computers were available. These systems began to support images with multiple colors. First advanced machines supported 16 or 256 colors only. In recent years, highly advanced computers are available. Most of the modern computers can support millions of colors in graphics.

The 2D graphics can further be categorized into two types-- vector and raster.

Vector graphics are created using paths, which typically are shapes, lines, letters, and other scalable objects. These types of graphics are used for designing signs, logos, and other types of drawings. vector graphics are highly scalable. They can be enlarged without affecting the quality. The Rater graphics are usually used in Web graphics, digital photos and icons. Raster graphics are created using pixel grids. Each of the pixels can be in different colors.

3D graphics became popular in the 1990s with the emergence of 3D rendering software such as CAD as well as 3D Animation Programs. By 2000, the 3D graphics started being used in video games. The computers of that age had the higher processing power. So, these systems were able to support the advanced graphics. The computers of the recent years are available with 3D video cards. So, handling the 3D image processing related works becomes easier. With higher processing power, modern computers can support advanced 3D applications and games.
