The document summarizes the history of animation from early devices like the zoetrope to modern techniques. It describes inventions like the zoetrope (early 1800s), thaumatrope (1824), phenakistoscope (1831), flip book (1868), and praxinoscope (1877) which helped develop the illusion of motion. Modern animation techniques discussed include traditional/hand drawn animation, stop motion which moves objects slightly between photos, and CGI/computer-generated imagery done on 3D software, with Toy Story cited as the first fully CGI animated film.
