Animation involves rapidly displaying a sequence of images to create the illusion of movement. There are several types of animation including full animation which uses highly detailed drawings and movements to look realistic, limited animation which uses a more stylized approach to keep costs down, and rotoscoping which involves tracing live-action footage frame-by-frame. Stop motion animation physically manipulates real-world objects frame-by-frame to also create the illusion of movement, while computer animation uses digital tools and software to generate animated images and movements.
