Description
4D cinemas is a new digital technology based on the technology of
3D cinema, and mixed with various complicated special effects of
scenes such as flashing, snowflake, shocks, water spraying, and
wind blowing and so on! 4D cinema is a newly raised international
movie style which has been developed from the basis of traditional
stereo cinema. Compared with cinemas of other types, it boasts
features and advantages of prominent theme, high technology, vivid
effect and viewer-attracting. It can bring the viewers strong
incentive on visual, listening, touching or even smelling
sensation, and bring an all-round feeling to all the sensory
organs.
Generally, 4D cinema is made up of three elements: stereo
projection system, shaking seats and special effect equipment and
computer-controlling system. The three elements work jointly, and
form a system that stimulates the visual, listening, touching and
feeling organs. In this way, the environment referred to in the
theme of the movie, various details in the environment, and the
experience the viewers may encounter under certain environment
could be reappeared, and a general effect of being personally on
the scene could be achieved.
4D cinema is developed from the basis of traditional stereo cinema.
Compared with cinemas of other types, it is popular with features
and advantages of prominent theme, high technology, vivid effect
and strong screen impacts. With the development of entertainment
technology and the requirement of the entertainment market, people
not only bring about the special effects such as shocks, crashing,
wind blowing, water spraying and scratching to 3D cinema, but also
carefully design effects like smog, rain, flashing, bubbles and
smell, forming a special experience. This is the 4D cinema which is
quite popular nowadays. Now that the viewers can obtain all-round
feelings in vision, listening, touching and smelling, the
development of 4D cinemas has been very fast in the past
years.
The
configurations of 4D Cinema:
One Screen Structure of 4D
Cinema
Visually speaking, cylinder screen-circulating stereo vision of **0
degree is adopted—i.e., the screen is kept on a radian with the
same center of circle, but not on a surface (screen). The
proportion of height and width of the screen is *6:9. The vision
scope of cylinder screen-circulating 3D object movement is largely
extended, and the vision is broadened. The limitation of graphic
vision is got rid of so that the visual space and the factual space
get more close, and multiple movement ways such as traversing and
revolving, thus bringing about the feeling of change of time and
space. (Different from “graphic four-dimension vision”—restricting
visual angle of the viewers as well as movement directions of the
objects.)
Two Polarized Light
Glasses
As to the requirement of cylindervisual effects, we
specially designed and produced cylinder polarized light glasses which are fit for
seeingcylinder films (i.e., the stereo glasses). The images
seen in the left and right eyes of the viewers are different, and
the image reflected in people’s brain is 3D image. Consequently, a
stereo visual space of being personally on the spot is
created.
Three 4D Special
Effect Seats
The motion seats will carry out five special effects controlled by
the computers according to the plots of stories. They are crash,
shocks, wind blowing, water spraying and leg patting. Added the
smog, rain, flashing, bubbles, smell, scenery and figure show to 3D
cinema, and all of people’s sensory system is mobilized so that
they can enter the plots of the film. The film plots in
four-dimension visions have employed the above special effects, and
combine the viewers and spot feelings. Therefore, the viewers can
obtain all-round feelings in vision, listening, touching and
smelling, and experience the feeling of being personally on the
spot and in the dream. A special performance means is then formed.
This is 4D cinema which has been very popular nowadays. Through a
serials of technology modification and renovation, 4D cinema has
broken through the traditional concept that movie is a lighting
art. It is a brand new and hi-tech product.
Four Digital
Sound Systems.
High-quality sound effect materials are employed—multiple sound
channels revolving sound system is adopted as sound system of the
cinema. The 6.1 or even 7.1 sound system is provided so as to
strengthen the sound effect. (For example, increase sound channels
to imitate plane flying and thundering.) The design and production
of multiple sound channels revolving sound system of 4D cinema has
fully taken into consideration that cylinder 4D cinema enables 3D
objects to make revolving movements and fix the position of moving
objects accurately so that the sound of 4D cinema also become
stereo and form a real stereo space.
4D Cinema:
4D cinema is a new film product based on 3D stereo movie and added
the imitation of special effects of the environment. The so-called
4D cinema, is also named “four-dimension film”; that is, the
three-dimension stereo movie and the surrounding environment are
imitated to compound a four-dimension space. While the viewers are
seeing stereo movies, with the change of the content, they can
actually feel the events corresponding to the stereo images such as
storm, lightening, raining, crashing, water spraying and leg
patting. The seats of 4D cinema possess the functions of water
spraying, raining, lightening and smog, which are motivated by
pneumatic power. Environment imitation simulation means that the
cinema is equipped with special effect equipment such as snowing,
raining, lightening and smog so as to build an environment
correspondent to the content of the movie. Both of the above movies
have the effect of being personally on the spot and thrilling of
danger. These two movies not only shares common characteristics but
also have their individualities. Being personally on the spot,
thrilling of danger and feeling technology are their common
characteristics; one is feeling excitement in movement, the other
is feeling excitement in vision, and these are their
individualities.
Three-dimension movie, i.e. the 4D movie we often refer to, is the
product of the combination of stereo movie and special effect
cinema. With the broader application of three-dimension software in
our country, 4D cinema has enjoyed fast development. Producing
stereo movie by using three-dimension software has its special
advantages. For example, the three-dimension scene has stereo
characteristic itself, so all kinds of parameters relevant to
stereoscopic images are quite easy to be adjusted in the software
environment. This article elaborates on the theory of
three-dimension stereo movie production and resolution means of
frequently asked questions. Later on we will make further
discussion on detailed production. It is our wish that the friends
who are interested in stereo movies won’t miss it.
4D movie is the product of the combination of stereo movie and
special effect cinema. Besides stereo visual images, the showing
spot can imitate natural phenomena such as lightening, smog,
snowflake, smell and so on. The viewers’ seats can also make
movements like dropping, shocks, wind blowing, water spraying, leg
sweeping and so on. These spot special effects and stereo images
combine closely with the plots, and bring a brand new entertainment
effect to the viewers’ vision and body experience, which make them
feel being on the spot and stimulative.
The earliest 4D cinema appeared in America. Many famous programs
like “Spiderman”, “Soaring over California” and “T2” have widely
applied the styles of 4D cinema. In recent years, with the wide
application of three-dimension software to the production of stereo
movies, 4D movies have enjoyed fast development in our country, and
the production level of image effects and spot special effects have
made great progress. Scores of 4D cinemas have appeared in
Shenzhen, Beijing, Shanghai, Dalian and Chengdu. Most of these
cinemas appear in various theme parks and science popularization
places, and are profoundly enjoyed by the viewers and
tourists.
Producing stereo movie by using three-dimension software has its
own advantages. For example, the three-dimension scene has stereo
characteristic itself, so all kinds of parameters relevant to
stereoscopic images are quite easy to be adjusted in the software
environment. Therefore, after the three-dimension computer
technology has been applied to the movie industry, three-dimension
movies appear quickly, such as 3D movies and 4D movies which have
been commonly referred to by us. Spiderman in the Disneyland of
America has further resolved “three-dimension stereo tracking and
rendering” technology, which makes the stereo scenes in the screen
automatically alter the perspective relation according to the
moving track of the tourists, and maintain concurring and
consecutive perspective relation between virtual scene
(three-dimension screen) and live scene (live settings), thus the
sense of reality of the screen is promoted a lot.
The reason why we human beings can see stereo sceneries is that our
eyes can see things respectively. That is, the left eye can only
see the sceneries in the left eye, while the right eye
can only see the sceneries in the right eye. Because there is space
between the left and right eyes of human being, there are tiny
differences between the visual angles of the two eyes, and such
differences can bring about a little position change of the
sceneries seen by the two eyes. The image difference between the
left eye and the right eye is called parallax error. The brain of
human being combines the images of the two eyes together subtly,
and produces the stereo visual effect with the sense of space in
the brain.
Because there is only one computer screen, but we
have got two eyes and have to separate the images seen by the left
eye and the right eye respectively so as to catch the stereo
feeling. Then, we can display the parallax error continuously on
the screen by using the stereo glasses. By controlling the IC, the
stereo signal is sent to the screen (left eye→right
eye→left eye→right
eye→alter repeatedly), and synchronous signal is sent
to the stereo glasses so that the images of the left and right eyes
can be synchronously altered. In other words, the left eye sees
images it should see, and so does the right eye. Stereo glasses are
piercing liquid crystal glasses. By controlling the switch of the
liquid crystal glasses with electric circuit, the glasses will turn
all black and the image of one eye will be shut out when turning on
the switch; the glasses will turn transparent and the other eye can
see images it should see. Stereo glasses can imitate the real
situation and images of the left and right eyes will appear on the
screen continuously and alternately. Coordinated with the stereo
glasses, and added the physiological characteristic of vision
holding of our eyes, we are able to see the real stereo
images.
