Animation is used to model and render virtual characters in several animation movies. There are different types of animations like stop motion animation, 2D cell animation and there are other techniques like claymation. The most advanced and prevalent technique used in animation is 3D animation which uses software like Maya and 3D Studio Max. Another technique incorporated in these animation styles is motion capture which uses live actors to create and record movements in prerendered models to give them a realistic human movement. Animation is also used to create fantastic surreal backgrounds for live actors and helps save on costs of creating expensive setups and scenes. It also helps on costs by creating virtual stunts which look realistic and are then superimposed with the movie. Besides that, extensive animation work is required in video games as well.
