Editing Computer animation (section)

==2D computer animation==
[[2D computer graphics]] are still used for stylistic, low bandwidth, and faster [[real-time rendering]]s.

Computer animation is essentially a digital successor to [[stop motion]] techniques, but using 3D models, and [[traditional animation]] techniques using frame-by-frame animation of 2D illustrations.

For 2D figure animations, separate objects (illustrations) and separate transparent layers are used with or without that virtual skeleton.

===2D sprites and pseudocode===
In 2D computer animation, moving objects are often referred to as "[[sprite (computer graphics)|sprites]]." A sprite is an image that has a location associated with it. The location of the sprite is changed slightly, between each displayed frame, to make the sprite appear to move.{{sfn|Masson|1999|p=123}} The following [[pseudocode]] makes a sprite move from left to right:

 '''var''' ''int'' x := 0, y := screenHeight / 2;
 '''while''' x < screenWidth
 drawBackground()
 drawSpriteAtXY (x, y) ''// draw on top of the background''
 x := x + 5 ''// move to the right''

===Computer-assisted animation===
Computer-assisted animation is usually classed as two-dimensional ([[2D computer graphics|2D]]) animation and is also known as digital ink and paint. Drawings are either hand drawn (pencil to paper) or interactively drawn (on the computer) using different assisting appliances and are positioned into specific software packages. Within the [[software]] package, the creator places drawings into different [[key frame]]s which fundamentally create an outline of the most important movements.{{sfn|Masson|1999|p=115}} The computer then fills in the "in-between frames", a process commonly known as [[Inbetweening|Tweening]].{{sfn|Masson|1999|p=284}} Computer-assisted animation employs new technologies to produce content faster than is possible with [[traditional animation]], while still retaining the stylistic elements of traditionally drawn characters or objects.<ref name="Roos">{{cite web |last=Roos |first=Dave |date=2013 |title=How Computer Animation Works |url=http://entertainment.howstuffworks.com/computer-animation.htm |access-date=2013-02-15 |publisher=HowStuffWorks}}</ref>

Examples of films produced using computer-assisted animation are the rainbow sequence at the end of [[The Little Mermaid (1989 film)|''The Little Mermaid'']] (the rest of the films listed use digital ink and paint in their entirety), ''[[The Rescuers Down Under]]'', [[Beauty and the Beast (1991 film)|''Beauty and the Beast'']], ''[[Aladdin (1992 Disney film)|Aladdin]]'', ''[[The Lion King]]'', [[Pocahontas (1995 film)|''Pocahontas'']], [[The Hunchback of Notre Dame (1996 film)|''The Hunchback of Notre Dame'']], ''[[Hercules (1997 film)|Hercules]]'', [[Mulan (1998 film)|''Mulan'']], ''[[Tarzan (1999 film)|Tarzan]]'', ''[[We're Back! A Dinosaur's Story (film)|We're Back! A Dinosaur's Story]]'', ''[[Balto (film)|Balto]]'', ''[[Anastasia (1997 film)|Anastasia]]'', ''[[Titan A.E.]]'', ''[[The Prince of Egypt]]'', ''[[The Road to El Dorado]]'', ''[[Spirit: Stallion of the Cimarron]]'' and ''[[Sinbad: Legend of the Seven Seas]]''.
