Computer-generated imagery Computer-generated imagery (CGI) is the application of the field of computer graphics or, more specifically, 3D computer graphics to special effects in art , video games , films , television programs , commercials , simulators and simulation generally, and printed media. The visual scenes may be either dynamic or static. Here is a picture made with computer-generated imagery, modern architects use services from computer graphic firms to create 3D models for both customers and builders. These computer generated models can be more accurate than traditional drawings.
Take a look at the movies in the last two decades, all these high-tech movies were definitely the most splendid wonders, the top 10 global box-office were achieved by these films. In Hollywood, computers and digital technology has become more and more important, and provided a set of producing methods and tools. Therefore, the academy of motion picture arts and sciences announced a new scientific and technical award since the 68th Oscar award. The American computer-generated imagery first initiated in military and aerospace industry.
At that time, the equipment are super huge and the producing proceed is quiet difficult. After the 1980s, computer-generated imagery has become increasingly matured. A few of film makers start to try this technology to make their stories more convincing. In the 1990s, computer-generated imagery is widely used in the film making industry. During this period, the visual images created with computer-generated imagery have conquered the audience, the box- office of films has made unprecedented breakthroughs.
The new technology brought film making industry into a new phase and strengthened the leading place of Hollywood movies all over the world.
Thanks to computer- generated imagery, the audience may experience a fresh new sensory feast of movies. The representative film during this period is the Jurassic park (1993), it’s the first film made by computer 3D animation technology, the dinosaurs In the movie look totally real. Making people feel their imagination can be turned into reality is the ultimate purpose of the film makers, however, it’s tough to fulfill.
The birth of the computer-generated imagery has helped the film makers realize their imaginations and thoughts. The functions of computer-generated imagery 1: the creator can change any part of the input image’s shape, size, color and speed, then process 3D images. Do you remember the octopus captain in the film? His octopus-like face is made in this way. 2: produce non-existent scenes that cannot be photographed, combine them with real scenes. Example, 3: create artificial characters with the help of models. Such as the lovely mouse in . 4: simulate or duplicate real people.
In a movie, nothing is more important than men. But with regard to a film maker, it’s difficult to employ hundreds of thousands people to shoot a big scene, such as a scene of student demonstration or a battle. The simulate actor can perform as a replacement of the real actor, so that the audience can see a series of breathtaking and dangerous movie scenes. Example :< Forrest Gump>, there are a lot of people in this scene, but actually, among the crowd, about 100 people are real, the other people are duplicated by computers. the postures in the movie are highly challenging.
At present, computer-generated imagery has been widely adopted in the process of film making, especially in science fiction films and disaster films. New styles and all kinds of surrealistic fantasies have been realized one by one in the Hollywood movies in the late 1990s. Computer-generated imagery has come of age and created visual wonders continually in recent years. It’s changing the audience’s view experiences and expanding their desire of seeking novelties, changes and differences. Need is the best catalyst of innovation, I’m convinced that high-tech in Hollywood movies will be more prosperous in the 21st century, let’s wait and see.
