Special Effects in Animation and Live-Action
Special Effects in
the film industry has grown tremendously, this method gives a film a cool feel,
It is an interesting way to tell a story in a more believable way. Many
directors have used many elements to make their films more interesting since
the end of the 1800s. Directors have used animation, and stop motion to make a
believable story and capture the audience’s attention. Movies such as the King
Kong are a perfect way of using stop motion, and many more special effects were
added to many other films that it became a really important part of the film
industry. In the 1990’s computer
Generated imagery (CGI) had evolved and gave the filmmaker the opportunity to
be much more realistic and maintain safety while doing the effects. Computer revolutionized
the way audience see movies because of its possibilities and the endless amount
of effects that can be created and added it films. In this paper I will compare
special effect between the waves from the movie Deep Impact (1998) and the
waves from the animated movie Surf’s Up. They both are computer generated and
they are both realistic waves and oceans although in different styles.
Deep
Impact
In
the movie Deep Impact (1998) the water looks very realistic although it might
not be correct in terms of speed, force, texture the especial effect artist did
a very good job to make it believable. The transparency and the waves are very
well executed and framed nicely to give the up and down shot a very dramatic
scene. The transparency of this effect is close to the real liquid and it has a
nice feel of volume that makes it look heavy. In the movie Deep Impact, when
water is about to destroy New York city, it show the waves rise very high that
the actual scene looks very realistic. This special effect might have taken a ton
of computer-generated power to render; it is close to what would have happened
in the real scenario. However, many steps took place in order to made the scene
look real. For example, when the waves destroy the bridge, the artist had to
take off the plate of the bridge and replace it with a CG model.
Many of the special effects were created
using Softimage software and ILM’s proprietary code. The set that they built
the bridge, overtaking, the building, the cars, and the debris were made in Maya
3D or Alias back in 1998. And many live action shots took place and were
replaced with the CG model when they showed the destruction. The artist had to used tons of
references on how the ocean and waves behaves and well as the study of physics.
Artist also many scientific theory on how the water behave after the comet hits
the ocean just like in the movie deep impact. The particle system that they
used was a better choice but they couldn’t tell what was the exact result after
rendering. This effect took a long time to render since they rendered several
million particles and they had to use all the processors that they had in spite
of the powerful system that ILM had in place.
Surf’s
Up
Surf
up is a very interesting and complex animated movie. The way the production
used and integrated of live action and the wave rig system was unique because
of the way the animator interacted and animated the waves. However the system
was too sensitive that it could make the controls used to animate the waves look
unrealistic. At the same time to animate the waves they had to use a lot of
references on how water behaves, surface, trails, as well as whitewater
simulation. Animating the waves was a real challenge, as well as the care and
time that it took to make the waves work the waves were animated so the secondary
effect would follow in a nice manner. This wave animation was rendered in Maya,
Houdini, and render Man software. This process took many months, Parts of the
wave was made from Nurbes Primitives in Maya3D software and used many blend
shapes and lofted curves profile to made the waves, which were placed together
to made the waves. Many tests have to be done to make the look believable and
many wave trains. Animators used the Wave Visualizer system to simplify the
visual of the waves on how it was going to behave. Many particles were used to achieve
the look of whitewater or splash effect. Many other steps took place in order
to make the water. Rendering the
ocean by itself was or made a hole in the ocean with the displacement shader
was the best way to combine the ocean and the waves.
There were many other difficulties
or considerations about making a wave. The process took many months to develop,
such as wave patch, energy, wave variation and direction, but most of all the
most difficult task was to make the waves crashing from cross section. In
addition, the other difficult part was to add motion blur to the waves in order
to make it look very realistic.
Conclusion
Many
filmmakers have innovated the use of computers to make something much more
believable, and safe when making complex scene where it needs to show an explosion,
fire, blast, or any other dangerous attempt in place of creating a real explosion.
In the 1930’s many of the movies had created the special effects by using the
stop motion to create an effect that the characters were actually moving. Even
today the movies from that time still look very realistic. But with the
invention of the computer it is easier to make something very complex in order
to make something look very realistic. CGI has helped the filmmakers to make
live action, animated 3D films in a way that tells a story in a very convincing
way. In these movies Deep Impact and Surf’s Up, the waves are very realistic
even though they each are very different. One is more realistic and the other
is a stylized, but at the same time both are very complex to do but believable.

Outline for the Third Term Paper
Outline
for the Third Term Paper
For the third
paper I will write the thesis statement and I will be comparing the visual
effects of waves from the movies Deep Impact (1998) and Surf’s Up 2007.
Deep Impact
- Waves created by software:
- Realistic
- Textures
- Force
- Impact, and
- Speed
Surf’s Up
- Color
- Realistic
- Speed
- Height
- Texture
- Impacting
Conclusion:
I will incorporate
the thesis and give a brief statement of the essay. How bad are the effects in
each movie and the efficiency. And the difference between animated waves and
more realistic one.

Science Fact or Cinematic Fiction?
Movies have become very popular in the movie industry they
have become one of the highest grossing films. Directors use physics to make
their films look real, however in some of the movies physics goes beyond as
they break the rules of physics and become something believable, but at the
same time it is an exaggeration of what a real human would do in real life. This is true for fantasy stories,
comics, and animated films as well as action like: Falling, flying, punches, breaking walls, jumping and many more
actions that directors used in the movies. I will write my paper and analyzed
the exaggeration of physic that is applied in the movies such as Transformers
3, Van Helsing, and the Incredible Hulk.
In the Transformers movie the first
thing that is wrong is when the spaceship falls in the noon and explodes. dust
flies in the air and there is huge fire from the spaceship when it crashes.
However, that scene defies the third rule of Newton. “For every action, there
is an equal and opposite reaction.” In space as in the moon there is no air or
sound that can create a fire or explosion. The gravity is so strong that
everything just falls, and in this scene even the dust is shown as if there is
air or oxygen. An explosion needs oxygen in order to have a combustion like in
that scene. In addition, it is not possible to transport an object or matter
through space, in the movie the director used a laser ray to open a door to
earth. Another example, Tom falls in prime’s hand from a very decent height and
nothing happened to him. From that fall anybody would have died from hitting a
heavy metal like prime’s hand. The speed that the transformer moves is unreal
because they are made of heavy metal. The heavy object would have to start slow
and gain speed as it goes faster. The other scene in this film is when the
soldiers jump from a high rise building and use a special suit that spreads
under their arms like wins and allow them to fly, this action violates the rule
of Newton again because a fall like that would not allow a person fly, but just
free fall with out able to control it. In the scene they manage to fly around
the falling building without a risk of getting hurt. There are many more scenes
that defy the rule of physic in this movie.
Van helsing was another movie that defies
physics in many ways. For instance, the werewolf hops like he has not weight at
all. An animal about that size would have weighed a lot and would have not moved
as fast as he did in the movie. Another scene is when Anna has to slide down
using a rope in order to cross a broken bridge in the same scene she was like
half way down the rope and catches a knife in mid air with one hand while the
other holding a rope swung across then falls and bounces many times with out
getting hurt or at least getting a scratch. A fall from that distance would
have done serious damage or even kill a person. A real human would have not
bounced but just crashed to the ground. Another scene where they defy the rule
of physics is when Aleena flies and does many turns in the air with a speed
that makes her looks very blurry, in addition, her wings disappears like magic
and turn into a silk cloth. There is a scene where Aleena hits Anna and she
doesn’t even get any momentum; she just easy turn and hits her and Anna falls far
away and as she falls she slows down carefully and falls. This defies the rules
of Newton as falling objects gain speed when falling. The other scene that
violates the rules of physics is the fight scene between the wolf and the Dracula,
they both hit and fall hard on objects with out breaking any bones, this and
many scenes definitely defy physics in many ways.
The Incredible Hulk is a movie
based on the comic book and one of the movies that became a hit. However, this
movie defies physics in many ways. Firstoff, when Bruce converts into the hulk,
he breaks walls like paper as he escapes. This breaks the third rule of Newton:
“For every action, there is an equal and opposite reaction.” The exaggerated action
would hurt anybody who even punches the wall and would even make them bleed in
real life. Another action of The Incredible Hulk is the scene where he jumps, it
looks fine when he gains momentum; he runs and as he runs he starts jumping
which is fine considering his weight, however the jumping is way to exaggerated
because he jumps so far away as if he was rubber. Another violation to the rules
of Newton is an explosion where the Hulk flies out from the explosion, he does
not get hurt, only suffer a minor wound, which seals or heals instantly. Moreover,
another scene also showed that the Hulk gets mad and lifts a military tank like
lifting a table. Which is really cool visually, but cannot be applied in real
life and after that Hulk grabs the military tank, swings it and throws it far
away. Then he proceeds and bends one of the tanks to prevent it from firing. In
addition, there is this scene where hulk grabs a missile, bites the top of the
missile and spits it back at the helicopter. These scenes totally defy the rules
of physics. Yet another scene is when The Hulk grabs a rocket and it starts taking
him into space and he falls from that distance but tills lives.
Many of the films that are made
these days defy the rules of physics in order to make the movie interesting.
Some of the physics are apply, but some others are exaggerated just to make it
more interesting. The audience on the other hand, enjoys watching movies like
this because even though people cannot do that in real life. It is fun to see
and it is entertaining to watch the exaggeration of physics. In the movies that
I analyzed; Transformers 3 dark of the Moon, Van Helsing, and The Incredible
Hulk are movies that are impressing to watch, and as CGI movies continue to take
control in the film industry directors will continue to violate the laws of physics.
