Animation is the process of making films, videos, and computer games in which drawings or models of people and animals seem to move. There are three main types of animation: 2D animation which uses hand-drawn or computer-assisted 2D drawings; 3D animation which uses 3D digital objects; and stop motion animation which uses 2D or 3D real world objects. Camera movements that can be used in filmmaking include pans, tilts, pedestals, cranes, dollies/tracking, and zooms.
