Computer Images And Graphics

Screens work by displaying multiple images at a high speed in order to create the illusion that the image is actually moving. This article will be a description on how exactly that image is made. 

First, the image/video has to first be made. One of the ways this can work is by capturing some video using a camera. Cameras will receive light and convert that light into information. You can also simply just already create the video as an animation. Animation is when the computer will show an image and will slightly alter that image between each frame to make the image appear to be moving.  

A video file is basically information that can be understood by the computer to create an image or animation. 

A screen (Such as a TV or desktop monitor) can understand that information and convert it into an image that you can see/watch. 

3 dimensional images are a lot more complicated to explain. Basically, your computer uses smaller images, and layers and scales them to create the illusion of a 3D image that can be rotated. A similar principle applies to create a 3D model moving around in a virtual 3D space.  

This process is now more simplified since there we have already created computer programs to assist developers and designers in creating 3D images and virtual worlds. It was a lot simpler to create 2D pixelated images before, which is why those classic games (Such as Pacman and Mario) have relatively large pixels.  

Today, some of the greatest video games of all time (Terraria) still use pixel graphics for a few reasons. One reason is that pixelated images are easier to create, allowing developers to be able to create amazing images in smaller amounts of time. Animating them is although simpler, it can still lead to AMAZING animations and sprites. Here's an example of how EPIC pixelated sprites can look and move

Some great games in the making (Planet Centauri) ALSO use pixelated images and animation. This is because pixelated appears to have a classic "feel" on games. Here is another example.

Of course, games with realistic graphics are still amazing! Take CS: GO and Paladins for example. Having REALLY small pixels can allow the developers to create highly detailed projectiles, characters, and areas. This can also allow them to create really refined User Interface (UI). But of course, that is assuming that your device is POWERFUL enough to play the game at maximum quality.
