What is Computer graphics?
[[File:utah teapot simple 2.png|thumb|Rendering technique of the Utah teapot using 3D computer graphics model created by [[Martin Newell]] in 1975]] '''Computer graphics''' are visual representations of [[Information|data]], made with the help of [[computer|computers]]. Computer graphics can be a series of images ([[video]] or [[animation]]) or a single image. Computer graphics are very useful. [[Computer-generated imagery]] is used for [[movie]] making, [[video game]]s, [[computer program]] development, [[photo editing]], [[scientific modeling]], design for [[advertising]] and more. Some people see computer graphics as [[art]]. == Areas of computer graphics == Computer graphics can be [[2D]] or [[3D]]. They are made differently and used differently. People can use computer programs to make different types of graphics. === 2D graphics === 2D computer graphics are usually split into two categories: vector graphics and raster graphics. ==== Vector graphics ==== {{main|Vector graphics}} Vector graphics use [[line]]s, [[shape]]s and text to create a more complex image. If a vector graphic image is made very big on the monitor, it will still look as good (smooth) as its regular size. This is one of the reasons vector graphics are liked so much. Vector images also take very little computer memory when saved. Vector graphics are made with programs like [[Adobe Illustrator]] and [[Inkscape]], and were used for some older [[computer games]]. Today, they are often used for when computer graphics have to be printed out. ;Examples of vector graphics <gallery> Image:TheStructorr Lamborghini Gallardo.svg|A car.

Digital cameras create raster pictures but artists can make them with computers too. The artists don't have to change a single pixel at a time –⁠ raster programs often hav
