In 1877, Edweard Muybridge used a series of twelve cameras to capture a sequence of images of a galloping horse at the Palo Alto horse farm in California. When a series of sequential images is presented at a rate of ten to twenty images per second, the images are perceived as moving. In 1893, Muybridge used a mechanical animation machine to project a series of images before a paying audience at the Chicago World’s Fair. This became the basis of a motion picture industry that eventually led to today’s streaming movies. The principle that causes a series of sequential images to be perceived as animated is known as persistence of vision. The following labs will show how this phenomenon can be replicated using both computer simulations and physical mechanisms.
