How does animation work?

Animation has four different entries in the Oxford dictionary, the first is: an animated quality, second: an act of animating, thrid: a state of being animated and fourth: preparing animated cartoons. the forth entry is the one that we want. There are three main catagories of animation; stop motion, computer and other (according to wikipedia though). Stop motin is the biggest catagorie with at least ten different types: puppet, puppetoon, claymation, cutout, silhouette, model, go motion, object, graphic and pixilation. These types of animation require at least twenty-four frames a second because that is the speed where your brain can process the images as one. This is called persistence of vision, this theory states that the average human eye reacts to an image lasting for o.o4 seconds. This is why we can notice subliminal messages. Because the theory of persistance of vision exists we know that we can see twenty-four frames a second. Some helpful information about animation: It's cheaper than any other type of film making so it is cheaper.
