Applications of digital graphics for computer games

There are several ways digital graphics are used in the production of video games, including (but not restricted to):

Advertisement

Computer Graphics are used to advertise video games for several reasons. The main reason advertisers use computer graphics to show off the game is because it is the most accurate representation of the actual game, this makes the audience see what the finished game will feel like.

Game Cover

Digital graphics are used on game covers to attract people to it. The cover also shows the 'feeling' of the game, meaning it shows what the game will be like if you play it. It does this by showing what part of the environment will be like, maybe the cover will show a main character or npc's etc.

The cover of this game shows the main character at the centre of the image, npc's either side, with destroyed environment behind them all, this gives a very good impression on what the game will be like.



Logo's

Video game logo's use computer graphics because it is easy to generate and easy to change/alter during development. Also it is very easy to duplicate for multiple uses, like in advertisements, for in-game uses or for sequels in the series. The logo below was used for The Elder Scrolls V: Skyrim, but there was also a very similar logo used for The Elder Scrolls III: Morrowind.

Text/Subtitles

Text is made by digital graphics, this is so they can get the right font, size, colour etc. The text also has to fit with the theme and setting of the game, for example if the game is set in a futuristic environment you might want a more futuristic look like this.

Textures

The most obvious use of digital graphics in computer games are the textures. The textures are what make the 3D Models look like what they're supposed to. Textures can come on a variety of sizes, but always stick to 'The Power of 2', meaning resolutions of 8x8, 16x16, 32x32, 64x64, 128x128 etc. The bigger the textures, the better the game will look but it will also run slightly slower if the textures are too big. So because of this game developers have to come to a compromise on textures. Also the bigger the texture sizes, the bigger the file size which will take up more memory to install and run.
