the zoetrope
the
zoetrope was invented in 1834 by william George horner, was an early
form of motion picture projector that consisted of a drum containing a
set of still images that was turned in a circular fashion in order to
create the illusion of motion.
A
zoertrope is relatively easy to build. It can be turned at a variable
rate to create slow motion or speeded up effects. like other motion
simulation devices, the zoetrope depends on the fact that the human
retina retains a image about a tenth of a second so that if a new image
appears in that time, the sequence was seem to be uninterrupted and
continuous. It also depends on what is referred to as the phi
phenomenon, which observes that we try to make sense out of any sequence
of impressions, continuously relating to each other.
The
visual effect (loops - continuous movement) created by a zoetrope or
zoopraxiscope is still used today to create animation gifs and video
display technologies such as steaming video, which essentially create an
effect of motion by presenting discrete but closely related images one
after the other.
