Animation is the process of creating the illusion of motion by displaying a rapid sequence of images that differ slightly over time. There are many types of animation including 2D animation using techniques like hand drawing, 3D animation using software, and stop motion animation. Traditionally, animation was created using techniques like pencil and paper or multi-plane cameras, but now computers and software allow for more dynamic animation. Animation can be used in movies, games, advertisements, education, and scientific research to simulate processes or display them for analysis. It is also widely used in entertainment like animated television shows.
