Why is animation described as an illusion?

Animation is described as an illusion because it creates the perception of motion through a sequence of static images displayed in rapid succession. This phenomenon exploits the human brain's tendency to fill in gaps between images, making it appear as though characters and objects are moving. The principle of persistence of vision, where the eye retains an image for a brief moment after it disappears, plays a crucial role in this illusion. Ultimately, animation transforms stillness into a dynamic experience, captivating audiences with its lifelike representations.
