Watching the movie "Dinosaur", whether it is real or computer special effects, is very shocking. It is a movie with strong visual shock, especially the CGI technology it uses, which left a deep impression on me.

It was about 65 million years ago in the late Cretaceous. Arada is an Iguanodon, who lives on an island like heaven and has never seen his own kind. A group of lemurs raised him. After a sudden meteor shower destroyed the island, Arada and several lemurs escaped the disaster and drifted to the mainland to join a group of dinosaurs looking for a safe place to live. The lack of water and food and the constant invasion of bloodthirsty carnivorous dinosaurs always threaten their lives. With innovative ideas and sympathy for weak companions, Arada inevitably clashed with the ruthless and stubborn leader Crohn and his loyal subordinate bruton. With the support of Krone's sister Nila, Arada challenged the tradition and proved that the best way to survive is to adapt to the environment and unite with each other.

In this film, real-life shooting and three-dimensional animation are integrated, leaving no trace, and truly reaching the realm of Excellence; In addition, people's familiar traditional Disney style is organically combined with dinosaurs that talk like real people. This combination has brought us new enlightenment: the application of digital technology in film production is one of the most revolutionary changes in the film field, and its appearance will certainly have a far-reaching impact on the development of the film industry.

The whole film has more than 1300 special effects shots, which is the most complicated and spectacular film of its kind. Its digital special effects completely immerse the audience in the wonderful world of reality and illusion. In addition to the visual impact, the film also endows various biological characters with human emotions, allowing us to feel the powerful and shocking computer stunts of this film while being animated. Of course, the most striking thing about this film is that most of the background pictures use real scenes taken from all over the world. After processing, they look more like the environment where the protagonist lives. This sounds like the charm of CGI technology, which skillfully combines the beautiful scenery in real life with high-tech methods, which has caused us a lot of thinking.

So what exactly is CGI technology?

CGI technology, that is, computer generated imaging technology (CGI), referred to as "Gao Baozhen" digital technology. Its technical process is to decompose the image into pixels by computer or directly use pixel information capture means to change from analog to digital, and generate any object you want in the second creation. On the one hand, CGI technology is more realistic than traditional animation, and strives to create completely convincing virtual characters or things; On the other hand, CGI technology hopes to be more real than reality and more dramatic than drama. CGI technology is not only used to create some fantastic planets or surreal future cities, but also expected to achieve the same realistic effect as photos. CGI technology is a standard to determine the communication mode between Web server and external programs, so that external programs can generate HTML, images or other content, and the server handles them in the same way as non-external programs. So CGI program books can only let you generate statement content and dynamic content. The reason why CGI is used is because it is a well-defined and widely supported standard, and it is difficult to realize dynamic web pages without CGI.

Today, CGI technology has been more widely used in the creation of cartoons, which has become another new stage of its development. Comic creation has gone through three stages: hand-drawn animation, computer-aided animation and computer-generated animation. And computer-generated animation is the CGI technology we mentioned earlier. Since the 1990s, there has never been a film that won the Oscar for best visual effects every year without CGI technology. CGI technology does not need the intervention of cameras, but relies on computers to create a "virtual reality scene", a real and illusory three-dimensional space.

It is through the combination of computer animation and digital augmented reality background and the use of CGI technology that Walter Disney Company will bring its movie hobby into another thrilling dinosaur era. Dinosaur, the masterpiece of Disney Film Company in 2000, is one of the most visually shocking movies in Hollywood history. Its digital special effects completely immerse the audience in the wonderful world of reality and illusion. The film's 1300 special effects lens makes it the most complicated and spectacular film of its kind. In this film, * * * shows more than 30 kinds of prehistoric creatures, ranging from 12 inch long small dinosaurs to 120 foot high and 100 ton brachiosaurus. In addition to the visual impact, the story of this film is also very attractive.

In order to enhance the realism of the scene, two location teams traveled around the world in 18 months, capturing various fantasy backgrounds for this fairy tale which combined scientific facts with Disney's rich imagination. Real scenes shot by computer-controlled camera equipment are sent back to burbank's studio, separated frame by frame by a group of digital experts, and then seamlessly blended with prehistoric creatures created by computers. The breakthrough of skin and muscle movement simulation technology also makes these animals' every move lifelike and extremely real. In addition, * * * 48 animation designers participated in the production of Dinosaur. One third of them have traditional hand-drawn animation experience, one third have engaged in static photography, and the other third have computer animation background.

Every minute in Dinosaur has something to do with CGI, plus live shooting. From 12 inch lizard to 1200 foot weight 100 ton brachiosaurus, plus more than 30 prehistoric dinosaur species, all will be displayed on the screen through 1300 complex stunt lenses. In terms of real scenes, the film crew spent 18 months traveling around the world, such as Florida, Venezuela, Australia, Hawaii, Los Angeles, Death Valley, California and other places to find suitable shooting locations. Then it is scanned, synthesized and modified to create a Cretaceous scene. In order to make this film, the film crew used four wide-angle lens cameras. The data in the three-dimensional lens is used to control the camera. The top view of the scene will be implanted into the three-dimensional scene, which can help the technical director and animator to accurately synthesize CGI modeling into the real shot. In order to combine characters with the ground, animators sometimes use two-dimensional methods to generate shadows, and they also use Rotoscope technology. In order to make the soles of dinosaurs look like they are walking on the uneven ground covered with stones, technical directors usually use deformation methods, and sometimes if it is difficult, they simply hide their feet in stones; When dinosaurs lifted their feet off the ground, footprints were exposed, and texture painters had to add footprints to the sand. In order to decorate the characters with lights, Chris Peterson, who is in charge of lighting, used Disney's patented tool "Light Tool", which made them look like part of the background.

The whole movie uses close-ups in many places, although the computer-generated images are vivid. At the beginning of the film, the big dinosaur drove away the naughty little dinosaur with his feet. This photo is a close-up of a nest of dinosaur eggs and dinosaur feet. It is very accurate and scientific to observe the epidermis, texture and muscles of the foot and the subtle changes of these parts in the process of exercise, which is by no means something that a painter can accomplish alone. There is also a close-up of a similar scene, where a huge dinosaur steps on the dry yellow sand and crashes to the ground.

Besides dinosaurs, lemurs are also exquisitely designed. It is said that the production of lemur fur should be a big challenge at that time, because 1995 had almost no corresponding software available. They can only do it entirely by motivation. The short, straight or long, curly fur of lemurs is decorated by designers to look a little wet and dusty, which also meets the requirements of close-up shadows, making the fur have different luster. At the same time, it is commendable that because of anthropomorphic treatment, the expressions of these dinosaurs have become very complicated, and facial muscles, mouth movements, eye flexibility and tongue simulation have all been severely tested. However, almost all the films are shown in close-ups, and what they get is not doubt, but admiration. I think it is precisely because they are endowed with human feelings that we are equally moved when watching this film.

I think the production of "Dinosaur" is not just a movie, it is the prelude to a major film and television revolution and the fuse to promote the sudden change of the film and television industry. It not only brings brand-new production methods, but also changes the traditional film production process; But also has a strong influence on the essence and creative concept of the film. On the one hand, it is a new understanding of the nature of film. The nature of film as a recording medium is undergoing a revolution quietly under the impact of digitalization. I firmly believe that in the future development trend, CGI technology will be more and more widely used in digitalization, and the film and television industry will gradually change to digitalization. On the other hand, digital technology combines the illusory world with the world we think is real, reaching a new surreal realm. This kind of surrealism has been applied in our real life, which will be an important development trend in the future.

Since then, dinosaurs have appeared in many movies. For example, BC 1 10,000 years (1940), fantasia (1940), geocentric travel notes (1959), land forgotten by time (1975) and food. 1993, Jurassic Park showed the dinosaur image drawn by computer for the first time and became one of the most successful movies in history. Although modern people have never seen dinosaurs in the real sense, it is precisely because the more mysterious and attractive dinosaurs are that dinosaurs become a good theme for movies.

I've seen dinosaurs flying in the dust and splashing when they pass by. Even the vibration of wood is so lifelike that I really feel the role of CGI in film and television.

The film industry is changing, and IT technology is changing with each passing day. We have reason to believe that full 3D CGI movies will have the strength to challenge traditional movies.

A good movie not only shines brilliantly now, but also contributes more and more to society and its charm becomes more and more obvious as time goes by. I think Dinosaur should be such an epoch-making movie!

Hollywood has produced many excellent works, but the waves behind the Yangtze River push the waves before, and only by comparison can we distinguish them. Known as "three-dimensional animation", The Lion King, Toy Story and Titanic are far behind in technology, and still stay at the level of graphic painting, and their three-dimensional images are not realistic enough. But "Dinosaur" has turned from graphic painting to fine production, which is amazing with its false image and the organic combination of image and real scene.
