Extra Credit - 3d animation - YAY i did it.

 

I don't know how to export video in Maya so I rendered 24 frames and used Sam software to put them together. 

I am not sure how 3D video, because I don't have glasses with me. Hope it works with 3d glasses.

The Laws of Physics in an Animated Universe: Chicken Little

The Physics of the animal world stand on two legs: Chicken Little

Chicken Little was produced by Walt Disney Feature Animation in 2005. The story focuses on Chicken Little who is small courage character lives in a small town of Oakey Oaks. It starts with a chaos event of “the sky is falling”. No one believes in Chicken Little even his father, and it brings a big shame on him and his father. Thus, he tries to earn back credit for his family by entering baseball club and tournament, and hope to succeed like his father. Fortunately, he is mostly miss the ball, but gets a big hit at the end of the last game which makes him the hero of the town. At that night, a piece of “sky” falls on him again, and this time he has it with him. He calls his friends to come over and figure it out, but not his father because Chicken Little afraid the father will not believe him either way. The group find out that it is the piece of device belong to alien’s ship. The aliens appear to be invaders, so Chicken Little, his friends ring the bell to warn the town. However, the alien ran off, but left a lost child back. Thus, the town doesn’t get on time, and once again the town doesn’t believe him include his father. Next morning, a group of aliens’ ships attack and look for the child. His father realized that he needs to trust his son. Finally, Chicken Little, his friends and his father brings back the child to the parents and solve the misunderstanding. When this movie was made, it tells the story about the trust between father and son plus some amusing scene. Although it is the world of animal standing on two legs, there are some physical laws that are not realistic. The path of action in some scenes is not follow inertia law. An object moves as if there is another force enforces on it, but there is none. In addition, the law of physic in the movie is not unique, they contradict each other. In this essay, I will analyze the laws of physic and provide examples from different scenes.

There are many animations that have animals’ characters. In order to simplify the actions of the characters and makes it easier for the audience to believe, these characters was designed their physical form similar to human being.

The first law of physics to analyze is the Newton’s first law of motion – the law of inertia. This law states that every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. Thus, an object should change the movement when there is force applied to it. At very beginning of the movie, a giant ball water metal tank is rolling consistent on the road without slowing down. Even if the ball is heavy which have a lot of momentum, the object doesn’t slowing down although it appears many forces act again it. The animators make the ball digs up the road while rolling in order to create an image for audience that the ball is really heavy. However, the animators don’t think it is an obstacle which should slow the ball down significantly. The animators want to emphasize the ball is extremely heavy which destroy everything on its’ way. The ball even breaks a brick wall, it still not slowing down. It was made too exaggerated compare to the real life. In real life, even the ball does not stop rolling, the velocity of if should reduce significantly within the time of rolling, destroying the road and hitting the wall.

The Animators succeed create an image there is a significant huge force on the rolling ball by the heavy ball pushes up the road in front of it just like a ship push water to the side. However, audience will be able to realize that the action does not follow the law of physic if the scene is longer. In reality, an object like a ship pushes water, or an arrow push the air, it can be done easily because the matter of water and air can be separate easily, and the objects have narrow heads to cut off the bond, and it still create friction. In reality, a heavy rolling ball is able to crush the ground below it, but it cannot dig up a road ahead of it before it even touches.

Another example of the movie which does not follow the path of action is in the dodge ball scene. The direction of the balls changes significantly after it hits a flat wall wrongly. First the balls fly horizontal, hit the wall and change the angle which is about 45 degree, and again it hits the flat ceiling with a direction straight down. If a movement follows the physic law, the force act on the ball should be opposite direction when it hit the flat wall, so the ball should bound back at horizontal direction (It could be a bit off because the angle may not be 90 degree). It could happen only if the ball spinning which it is not in the movie. One good example in real life is racquetball. The animators could make it more realistic by letting the balls hit an edge of a tool and bound back instead of a flat wall.

The law of physic is not consistent on the film. On the staring scene, the rolling ball crushes any object on it way, but later it rolls up and bend a big sturdy tree, which will be break in the real world. The tree even acts as lever for the ball to fly up. Another inconsistent scene is in the beginning scene, when the giant ball fall off the tower, it bounds just little and rolls. On the other hand, after using the big tree as lever to takeoff, the ball bounds at least four times to a complete stop. The stop was made suddenly after destroy the mayor statute; in order to show the audience how terrified the cause of Chicken Little’s act. Although the audience may not realize it because it’s fun, the stop does not consistent with the beginning of the film, nor follow physic laws. The most realistic in the ball scene is bouncing a bit after falling of the tower because the metal ball isn’t elastic to bounce back as high as before although it should be broken when it hits the ground because of pressure of water. When making this scene, animators only focused on the funny part to attract audience, but did not consider careful about law of physic to make it more realistic.

I will discuss net force act on an object in this paragraph. In the scene that Chicken Little misses the school bus and runs to school. While rushing to school and crossing a street, he steps on chewing gum. The force of glue chewing gum sticks to him, and he is unable to take it off by his strength. He put a candy into his mouth to create glue which he sticks it on a running car in order to use car force helps him out of the gum. It is obvious that the mixture glue created by candy and water cannot carry a small kid. Even if the glue is able to carry Chicken Little because he’s so light, his arm will be broken due to a large force pulling him by looking at how high he reach after getting rid of the gum. A force comes from moving car acting on stand still kid is big enough to injury Chicken Little. Imaging what will happen to an adult standing on the street and catch a rear mirror of a running car. The force get hit in front of the car are equal to be dragged from behind the car. Thus in reality, this is the end of the story for Chicken Little.
Here is another type of mixture glue combination between his comb and water. Chicken Little use water in his mouth to wet his comb. Then use his comb to stick to a surface of a roof to help him climb up to the top while carrying the little alien kid. I never try it on real chicken’s comb to see if it can stick or not. Although the chicken comb might be sticky, it won’t be able to sustain the weight of Chicken Little. In addition to support my hypothesis, Chicken Little carries extra weight while climbing up.

Weak structure carries a much heavier object. Fish builds a tower by regular note book paper – outside wall only, and has no supporting frame. However, Fish somehow stands at the top of the tower which 3 times higher than him and plays King Kong star on top of the paper tower. He shifts it to one side, and jumps. His action applies a force on tower paper which can’t sustain that much force. This scene is totally unrealistic. Only the weight of Fish’s helmet is heavy enough to crush the paper tower. Thus, there is no way that the tower can sustain the weight of Fish.

This paragraph talks about gravity in the animation and the scenes are contradict each other  when Chicken Little use bottle soda as a rocket. For this analysis, let’s agree on the force of full bottle of soda is strong enough to carry Chicken Little more than ten feet height in the first time he uses it. The first time he uses the soda to break into school and he lands before the bottle because he has more mass than the empty bottle. This scene seems real because the empty bottle may have reached its terminal velocity. However, the second time he uses half bottle of soda to reach the school bell in order to warn the village about aliens. Only half of soda is used, but it is able to carry him much higher than the first time. It is definitely opposite with the law of physic – the bigger force, the longer distance. Thus, using half of the rocket soda, he should not able to reach the height three times more than the height of first time. Instead following the physic laws, the animators let the Chicken Little fly about three times higher with half of the force. It doesn’t look real, but it creates a feeling for audience that the main character is trying really hard this time in order to save his friends and warns the villagers. Thus, his determination gives him more power, the power even transfer to the bottle of soda. Similarly, the ending is a movie about a star chicken floats in midair with two sodas for a while then increasing speed up. According to inertia if he floats midair and no force is applied on him he should to remain floating.

After examining the laws of physics in Chicken Little, it is clear that the movie pay attention to laws of physic. Because of the exaggeration, audiences feel relief from the stress of the real world, so they can easily relax and enjoy the movie. Thus, the animators successful deliver the fun movie’s context of the bond between father and son.

3D Images -

 It looks like nuts and chips are in front of me. If I can get it, it free. haha

 Orginal no edit - look ok, but a bit blurry

  our class. woo ray ^_^. 

                                                      the projector look really stand out. I should have zoom the camera so that the projector even more "3D"

 These two pictures, I took them mysefl. It is a bit off of angle, so I have to rotate the 2nd picture to make it 3d. I try not to change the angle, but it doesn't seem right. Furthermore, there are people walking around, so don't look at them, it might give you headache.

 These two picture is off a lot so I have to change a bit to make it 3D. Bellow is the original one.

  bad example

It doesn't look great. However, if there is an object in between, I expect that will be awesome because it would appear the floor and object are quite far distance.


I like this assignment the most. I want to learn more about this because there is a new technology that let the viewers watch it with real color not  seeing red and blue.
I don't know if they can implant the 3d glasses right at the TV scene, so viewer don't need to ware glasses to watch TV.

Lighting a Scene in Maya

One-point lighting

 Two-point lighting

 Three-point lighting

 Extra: the light doesn't effect fur and paint I put in. I need to spend more time on this. It's hard but fun.

Building a Scene in Maya

Since it is the first time I use Maya, it takes me more than 2 hours to create two words. I intent to create the "L" word kicking a ball into middle of "D" word (have a net like soccer goal). I tried, but no luck.

Character Animation

I have no doll or figure. I use double clips and toothpicks create two dancers.
At first it's hard to stand, then I break the toothpick in order to make it stands easier.
It's hard to control so I have to take as many picture as I can to make it like dancing.

Reverse Video Reference of Walking - Clip C

No one carry the camera for me, so I used tripod. Thus, I have to capture the whole scene unlike the clip the camera follow the object.

Reverse Video Reference of Walking - Clip B

Reverse Video Reference of Walking - Clip A

It's a little bit off the scene, but this one is the best I did.

The Laws of Physics in an Animated Universe: Chicken Little

The Physics of the animal world stand on two legs: Chicken Little

Chicken Little was produced by Walt Disney Feature Animation in 2005. The story focuses on a courage chicken – Chicken Little in a small town of Oakey Oaks and an event of misunderstanding aliens’ invasion. At first no one believes in Chicken Little that “the sky is falling” and aliens invade. After aliens appear to be an invasion, Chicken Little, his friends and his father solve the misunderstanding. This movie is rated for family because the content is about trust between father and son plus some amusing scene which are not following physical law. The path of action in some scenes is not based on realistic. An object moves as if there is another force enforces on it, but there is none. In addition, the law of physic in the movie is not unique, it is contradict each other. In this essay, I will analyze the laws of physic and provide examples from different scenes.

The path of action in the animated film is not follow the first law of motion – inertia is any object in a state of uniform motion tends to remain in that state of motion unless a force is applied to it. At the beginning of the movie, a giant water metal ball is rolling consistent on the round without slowing down although it appears many forces act again the rolling object. It digs up the road while rolling, it hits street obstacle, and it even breaking a brick wall, but not slowing down at all. In reality, it should stops within the time rolling and hitting the wall because the friction of the dug up road should be able to slow it down significantly. The animators want to emphasize the ball is extremely heavy which destroy everything on its’ way. At the first look, it looks like the heavy ball pushes up the road in front of it. However, audience will be able to realize the rolling motion is not follow the law of physic if the scene is longer because in reality a perfect round ball cannot dig up the road ahead of it before it even touches. The heavy ball is only able to crush the ground below it if the rolling momentum is large enough. 

Another example of the movie that does not follow the right path of action is in the dodge ball scene. The direction of the balls changes significantly after the bound without any force act upon them. First the balls fly horizontal, hit the wall and change the angle, then hit the celling with a direction straight down. If a movement follows the physic law, the force act on the ball should be opposite direction when it hit the flat wall, so the ball should bound back at horizontal direction (It could be a bit off because the angle may not be 90 degree). However, in the scene the balls change about 45 degree after the first bound and second bound at the celling. It could happen only if the ball spinning which it is not in the movie.

 

The law of physic is not consistent on the film. On the staring scene, the rolling ball at first crush any object on it way, but later it rolls up and bend a big sturdy, which will be break in the real world, as a slop for it to fly up. In the beginning scene as well, when the giant ball fall off the tower it bounds just little and rolls. This one looks the most realistic in the first scene because metal ball isn’t elastic to bound back high. On the other hand, after get off the slop created by the big tree, the ball bounds at least four times to a complete stop although the height when it gets off the tree is much lower than the water tower. Moreover, when it bound on several cars, it appear to be lower and lower, but at the last stop it bound higher and crush the statute (picture below). When making this scene, animators only focus on the funny part to attract audience, but did not consider careful about law of physic to make it be realistic.

 

We will discuss net force act on an object in this paragraph. In the scene that Chicken Little misses the school bus and runs to school. While rushing to school and crossing a street, he steps on chewing gum. The force of glue chewing gum sticks to him, and he is unable to take it off by his strength. He put a candy into his mouth to create glue which he sticks it on a running car in order to use car force helps him out of the gum. In the animation, it’s successful, but in real life he will die or lose his arm. There is no need to discuss about glue created by candy and water can carry a small body. It is not possible. Even if the glue is able to carry Chicken Little because he’s so light, his arm will be broken with his body due to a large force by looking at how high he reach after getting rid of the gum. A force come from moving car act on no-motion is big enough to injury Chicken Little. The force get hit in front of the car are equal to be dragged from behind the car. In realistic, this is the end of the story for Chicken Little.
 

Here is another type of glue chemical combination between chicken’s comb and water. Chicken Little use water in his mouth wet his comb. Then use his comb to stick with a round roof to help him climb up to the top while carrying the little alien kid. I never try it on real chicken’s comb to see if it can stick or not, but I still believe it is not true. Although the chicken comb might be sticky, it won’t be able to sustain the weight of Chicken Little. In addition to support my hypothesis, Chicken Little carries extra weight while climbing up.

Weak structure carries a much heavier object. Fish builds a tower by paper – outside wall only, and has no supporting frame. Then Fish somehow at the top of the tower which 3 times higher than him and playing King Kong star on top of the paper tower. He shifts it to one side, and jumps. His action applies a force on tower paper which can’t sustain that much force. This scene is totally unrealistic. Only the weight of Fish’s helmet is heavy enough to crush the paper tower. Thus, there is no way that the tower can sustain the weight of Fish.
 

There are other scenes contradict others is when Chicken Little use bottle soda as a rocket. For this analysis, let’s agree on the force of full bottle of soda is strong enough to carry Chicken Little more than 10 feet height in the first time he uses it. This paragraph talks about gravity in the animation. The first time he uses the soda to break into school. He lands before the bottle because he has more mass than the empty bottle. This scene seems real because the empty bottle may have reached its terminal velocity. This time, it follows real world physic. However, the second time he uses a bottle of soda to reach the school bell in order to warn the village about aliens. Only half of soda is used, but it is able to bring him much higher than the first time. It is definitely opposite with the law of physic – the bigger force, the longer distance. In second time using half of the rocket soda, he should not able to reach that height because the height level cannot even get close to the first one. Instead following the physic laws, the animator let the Chicken Little flies about three times higher with half of the force. It doesn’t look real, but it creates a feeling for audience that the main character is much better this time in order to save his friends and warn the villagers. Thus, his determination gives him more power, the power even transfer to the bottle of soda.
 

The ending of the movie is a star chicken floats in midair with two soda rocket for a while then fly off. According to inertia if he floats midair and no force is applied on him he should to remain floating. Because it is the ending so I am not criticize it. Overall, the movie violates a lot of laws of physic. It even contradicts itself. This movie is not about supper natural, but there are some scenes that require the object or character to have supper strong structure. However, because of these unrealistic, audiences feel relief from the stress of the real world, so they can easily relax and enjoy the movie. The context of the movie is really good. The trust between father and son should be strong to have a happy family.
