History of Animation Part two

The Zoetrope

The second task that was carried out in today’s session was the research and creation of a Zoetrope. The zoetrope was invented in 1834 by William George Horner; it was an early form of a motion picture projector. A zoetrope comprises of a drum enclosing a set of motionless images that is rotated in a circular fashion to produce the illusion of motion (Zoetrope and Praxinoscope, 2010). 

According to Hayes (2011), ‘the Zoetrope is the wheel of life’; when you place a strip of drawn images inside the Zoetrope’s drum or circular spinning object, the images come to life when you look through the slots. This illusion is again due to the persistence of vision and the phi phenomenon. The persistent of vision is a stroboscopic effect; the images must be disturbed by periods of darkness for the illusion to take effect. For example, if you spin a zoetrope and look over the top of the cylinder (instead of through the slots), the images will become distorted and the illusion will be non-existent. 
Moreover, the Phi Phenomenon occurs as a consequence of human nature; the brain attempts to make sense from what is seen, therefore when the various pictures are close together our brains rapidly interpret an association between them (Wikipedia, 2014). 
The various 19th century animations, namely the, zoetrope, flipbook, thaumatrope, praxinoscope and phenakistoscope were all stages leading to the development of film and television. Media technologies today appear different at a glance however they share mutual properties to these optical toys from the 1800’s (Hayes, 2011). 
The question now arises as to how to create a zoetrope......?
Here is a step-by-step process of how we created a zoetrope in our groups:
Step 1: We found a circular lid for the base that could also be easily spun.
Step 2: We measured the circumference of the circular lid and cut a piece of black cardboard to the same length, to wrap around the lid. We also cut a piece of paper to the same circumference as the lid however the height of this was smaller than the black strip.
STEP 3
(Wikihow, 2014)
Step 3: We chose our images and decided that at this stage simplicity was key and a focus on the measurements was what was important; therefore it was decided that a bouncing ball would be a good example of an Illusion. We measured the length of the paper and divided it into 12 (as we wanted 12 images) and then measured the same distance between each image.
Step 4: The images were drawn and coloured and designed as a loop effect, so that the last image was similar to the first.

STEP 5
Step 5: Slits were cut into the black paper strip as shown in the demonstration to the left <<<<

Again each slit was measured to the same distance as the images.
Step 6: The paper comprising of the images was then sellotaped to the black strip and the black paper strip placed around the outside edge of the circular lid.
Step 7: Finally, the animation was placed onto a spinning drum and viewed through the slips.

History of Animation

Thaumatrope Animation

The aim of today’s lesson was to expand our knowledge further in relation to the history of animation by creating our own thaumatrope.

Dr John. A. Paris 
The creation of the thaumatrope, whose coined name relates to “turning marvel” or “wonder turner”, was based on the ideas of astronomer Sir John Herchel, many years before the toy came into popularity. This simple device was in wide circulation by 1826, and has been suggested to have been known much earlier than this. Although its history is associated with Herchel, its popularity throughout the 19th century has been attributed to a well-known London physicist, Dr. John A. Paris, who demonstrated this idea as persistence of vision to the Royal College of Physicians in 1824 (Herbert, no date). 

Thaumatropes were the first of many optical illusion toys, and simple devices that continued to provide animated entertainment until the development of modern cinemas (Aim centre for animation and interactive media, no date).  A thaumatrope can be described as a small disk, with an image drawn on each side of the disk that is attached to two pieces of string; when the strings are twirled quickly between the fingers, the motion causes the disk to rotate, first in one direction and then in the opposite. The faster the disk rotates, the greater the clarity of the illusion; the two images appear to blend into one, thus causing an optical illusion due to the persistence of vision (Historical Folk Toys, 1996)

While the thaumatrope is not able to generate animated scenes; as mentioned above it heavily relies on the persistence of vision concept that other optical toys also use to create the illusion of motion. Persistence of vision is the phenomenon where an afterimage is thought to persist for approximately one twenty-fifth of a second on the retina after the image has gone and is believed to be the explanation for motion perception (Orem, 2011; Aim centre for animation and interactive media, no date). 

During our seminars today we were asked to create our own individual thaumatropes; I chose to create an image of an eye and a closed eye. Limited information was deliberately given in terms of how to create this animation; therefore plenty of research took place when making this animation.   

First, an accurate circle template was produced out of card using a compass; second the image in which the individual perceived to create the optical illusion was chosen (in my case the open/closed eye). Secondly, the centre point of the circle was measured in order to draw the images on the same place on each side of the disk; followed by the drawing, which appeared to be the most difficult part of the task for me! 

Finally, the holes were punched on the edges of the disk (far right and far left) in order for the string to be inserted into each hole. Once the string had been tied into each hole, both pieces of string were twisted between the fingertips to transform the two images into a single image.

Here is an example of the step-by-step process that took place when creating my animation:
STEP 1
STEP 2 




STEP 3 
STEP 4 



















STEP 6 
STEP 5 






















Following completion of the thaumatrope, myself along with many other peers carrying out this task found a few limitations in terms of the design. First it was identified that due to the holes on either side of the card not being measured accurately, when twisting the thaumatrope, it appeared to spin awkwardly and not as fast and freely as it should. Clearly if the holes are not positioned in line with each other, it effects the twisting motion and slows the process down.
Secondly, the drawings on either side of the card again need to be measured to precision; as demonstrated in the images above, the open eye was not drawn to the same dimensions as the closed eye, therefore the image became distorted. 


Despite these downfalls however, researching and creating a thaumatrope was an enjoyable task, and contributed to our understanding of the development of animations.
