Computer Graphics


Computer Graphics, including graphics and animation, as well as ultra-realistic images. The way in which computers paint, color, shade, and transform shapes is known as computer graphics.


Indeed, computer graphics enable us to collect, display, and understand information quickly and effectively.


Computer graphics also give us images of things and processes that we have no other way to see, such as the core of a molecule or a process in a black hole.


Uses of computer graphics

  • Computer graphics have many uses in a wide variety of fields, as companies follow up their sales from maps and pictures drawn by computers.
  • Computer graphics help engineers create and test designs for products such as cars and airplanes.
  • It also helps them see 3D building designs from any angle. Scientists use computer graphics to design new drug molecules, track weather devices, or test theories describing how galaxies were formed.
  • Doctors use computer-generated images of internal body parts to locate tumors and other disorders and to decide on treatment.


These illustrations show how computers enable factory owners to check and evaluate their product designs.


Computer Graphics

In the first step, the computer draws a diagram of the car in the form of a grid of lines.


In the second step, the computer fills in the spaces between the lines to show what the exterior of the car looks like.


In the third step, the computer adds colors, shadows, reflections, and lights to create a realistic picture.

Computer graphics are also used in art, in the production of animated films and some special effects in films, as well as in video games.


Computer graphics appear on a computer screen, and it resembles a television screen. The screen consists of thousands of tiny pixels called picture elements or pixels that compose the image.


From here, you can see individual dots by closely looking at the characters that appear on the computer screen.


The computer can illuminate and dim each point like a light bulb, in order to make a model. The different unions of points can produce any image we want.


And all computers need a program that tells them what to do. Here, the computer graphics program directs the drawing on the computer screen. The program may create the image itself or it may copy an image from another source.


A program that maps molecules, for example, may begin by solving equations describing the molecular structure, and then it can use the solutions to display the shape of the molecule. But a program that copies an image might convert the pixels on the image to a list of numbers first. The numbers then direct the computer to the spots that it turns on or off.
