Thursday: The kind substitute has the key to the review test. You can check it if you wish. Test Friday (unless you have talked to me. If you don't understand, call me)
Today you need to use Excel to generate an
x-y scatter graph for each of your three data sets. Save the file and then send it via email to marciarpowell AT gmail.com. Print a copy of each graph for your team to use.
JOURNAL WORKWrite in your journal about the following problem: Are videos made with computer animation better than those drawn by hand? Write this as a hypothesis, in INK.
Then, take a look at each graph you made with Excel. How well did the animator achieve what s/he was trying to do? Create an a-t graph for one of the acceleration sets in your journal...is it realistic? Create a d-t graph for the constant velocity motion and copy into your journal...is that realistic?
On the remaining data set that you have not used, try to identify as many of the five formulaic variables as possible, and include these in your journal. Why are these important?
MORE ANALYSISClick
here for the computer generated video to analyze. Again, make three x-y scatter graphs and email to marciarpowell AT gmail.com for your group
MORE JOURNALING (Whew!)Which is better: hand animated or computer animated cartoons? Answer this question for horizontal acceleration, vertical acceleration, and constant speed.
Study for test
==========
Friday: test
Write a one to two page summary of your and ideas about animation techniques in your journal, and how the laws of physics are replaced by the laws of cartooning, found below. What have you learned about reality vs. cartooning?
Cartoon Law I
Any body suspended in space will remain in space until made aware of its situation. Daffy Duck steps off a cliff, expecting further pastureland. He loiters in midair, soliloquizing flippantly, until he chances to look down. At this point, the familiar principle of 32 feet per second per second takes over.
Cartoon Law II
Any body in motion will tend to remain in motion until solid matter intervenes suddenly. Whether shot from a cannon or in hot pursuit on foot, cartoon characters are so absolute in their momentum that only a telephone pole or an outsize boulder retards their forward motion absolutely. Sir Isaac Newton called this sudden termination of motion the stooge's surcease.
Cartoon Law III
Any body passing through solid matter will leave a perforation conforming to its perimeter. Also called the silhouette of passage, this phenomenon is the speciality of victims of directed-pressure explosions and of reckless cowards who are so eager to escape that they exit directly through the wall of a house, leaving a cookie-cutout-perfect hole. The threat of skunks or matrimony often catalyzes this reaction.
Cartoon Law IV
The time required for an object to fall twenty stories is greater than or equal to the time it takes for whoever knocked it off the ledge to spiral down twenty flights to attempt to capture it unbroken. Such an object is inevitably priceless, the attempt to capture it inevitably unsuccessful.
Cartoon Law V
All principles of gravity are negated by fear. Psychic forces are sufficient in most bodies for a shock to propel them directly away from the earth's surface. A spooky noise or an adversary's signature sound will induce motion upward, usually to the cradle of a chandelier, a treetop, or the crest of a flagpole. The feet of a character who is running or the wheels of a speeding auto need never touch the ground, especially when in flight.
Cartoon Law VI
As speed increases, objects can be in several places at once. This is particularly true of tooth-and-claw fights, in which a character's head may be glimpsed emerging from the cloud of altercation at several places simultaneously. This effect is common as well among bodies that are spinning or being throttled.
A wacky character has the option of self-replication only at manic high speeds and may ricochet off walls to achieve the velocity required.
Cartoon Law VII
Certain bodies can pass through solid walls painted to resemble tunnel entrances; others cannot. This trompe l'oeil inconsistency has baffled generations, but at least it is known that whoever paints an entrance on a wall's surface to trick an opponent will be unable to pursue him into this theoretical space.
The painter is flattened against the wall when he attempts to follow into the painting. This is ultimately a problem of art, not of science.
Cartoon Law VIII
Any violent rearrangement of feline matter is impermanent. Cartoon cats possess even more deaths than the traditional nine lives might comfortably afford. They can be decimated, spliced, splayed, accordion-pleated, spindled, or disassembled, but they cannot be destroyed. After a few moments of blinking self pity, they reinflate, elongate, snap back, or solidify.
Corollary:
A cat will assume the shape of its container.
Cartoon Law IX
Everything falls faster than an anvil.
Cartoon Law X
For every vengeance there is an equal and opposite revengeance. This is the one law of animated cartoon motion that also applies to the physical world at large. For that reason, we need the relief of watching it happen to a duck instead.
Cartoon Law Amendment A
A sharp object will always propel a character upward. When poked (usually in the buttocks) with a sharp object (usually a pin), a character will defy gravity by shooting straight up, with great velocity.
Cartoon Law Amendment B
The laws of object permanence are nullified for "cool" characters. Characters who are intended to be "cool" can make previously nonexistent objects appear from behind their backs at will. For instance, the Road Runner can materialize signs to express himself without speaking.
Cartoon Law Amendment C
Explosive weapons cannot cause fatal injuries. They merely turn characters temporarily black and smokey.
Cartoon Law Amendment D
Gravity is transmitted by slow-moving waves of large wavelengths. Their operation can be wittnessed by observing the behavior of a canine suspended over a large vertical drop. Its feet will begin to fall first, causing its legs to stretch. As the wave reaches its torso, that part will begin to fall, causing the neck to strech. As the head begins to fall, tension is released and the canine will resume its regular proportions until such time as it strikes the ground.
