I've been taking some courses in Computer Science lately and had the opportunity to take a more ethics-based class this last semester. As part of that class, I had to write a series of papers delving into where computer technology started and where I see it ending up. Ultimately, we had to have a general theme as computer technology can be rather broad. I chose entertainment for my theme, partially as a bit of a challenge to myself, and partially because it can be an interesting field.
Below is the first of the three papers I wrote.
In the beginning, before formal written languages, man told stories. Stories provided news, knowledge, and entertainment. Storytelling was often a group event, with well-known storytellers providing the entertainment through both spoken word and, often, music accompaniment. As time passed, storytelling became more elaborate. Stories were performed in front of audiences, and eventually written down after a formal writing language was developed.
In the late 1800's, radio was developed. While initially used as a tool for disseminating important information, radio was quickly adapted to provide entertainment for the masses. Both music and stories were broadcast to mass audiences. By the 1920's, it was not uncommon for families to gather around their radio to listen to the latest broadcast of their favorite program.
In the early 1930's, the commercialization of television helped to quickly replace radio as the primary source of home entertainment. As with radio, families gathered around the television to watch their favorite program, immersing themselves in their entertainment. With this new medium, entertainers were determined to push the envelope, seeking the very limits of the technology available.
Alongside the development of both radio and television, scientists and mathematicians were progressing towards development of mechanical and, later, electronic computers. Initially, computers were used primarily for calculation. During World War II, computers such as the Colossus were used to break enemy ciphers.
By the late 1950's, computers were being used at businesses and colleges across the country, primarily for financial calculations. Colleges made computers available to graduate students who used them for research and course work. In many instances, tinkers and hackers gained access to these computers as well. Their goal was not to use the computers as they were intended, but to push the limits of the system and learn as much as they could in the process. Inevitably, the use of computers turned to entertainment as well as utilitarian functions. In 1959, a professor at MIT, John McCarthy, was working on a program for the IBM 704 that would play chess. Some of the grad students working with him devised a program that used a row of lights on the 704 to play a primitive game of Ping Pong. [1]
As computers advanced and moved from rows of lights on a console to integration with video devices, graphical capabilities increased as well. In the early 1960's, MIT students created interactive graphical programs on the IBM TX-0. Ivan Sutherland created a program called SketchPad which would allow a user to draw shapes on a computer screen using a light pen. Steve Russell created one of the first video games, Spacewar. These programs marked early attempts at using computers for entertainment purposes. [1]
By 1966, Ralph Baer designed a game console called the Brown Box. Magnavox licensed the system and marketed it to the general public in 1972 as The Odyssey. The Odyssey connected to a user's television and manipulated points of light on the screen. Plastic overlays were used as backgrounds for the games as advanced graphics manipulation was not yet available. [2]
Around the same time that video games were being invented, other computer scientists were working on generating more advanced graphical capabilities for computers. At Cornell in 1965, Professor Donald Greenberg worked with a number of architecture students to develop a computer animated movie about how Cornell was built. Greenberg went on to start the Program of Computer Graphics at Cornell and work on photorealistic rendering. He is considered to be one of the forerunners in the field. [3]
At the University of Utah, Ivan Sutherland, who previously created Sketchpad, joined the Computer Science department and began teaching computer graphics. One of his student, Ed Catmull, would go on to become a pioneer in computer graphics, developing some of the most common graphical techniques used today.
In the early 1970's, a number of animation studios were formed. Among these were Information International Inc. (Triple I) and Lucasfilm. One of the primary purposes of these new studios was to use computers along with traditional motion picture film. While most of these new studios quickly went out of business, a few, such as Lucasfilm, were quite successful and continue to be innovative today. [4]
In 1973, the movie Westworld was released. This movie marked the first use of Computer Generated Imagery, CGI, in a major motion picture. Technicians at Triple I used digital processing techniques to pixelate a portion of the movie, providing the movie watcher a unique view of one of the main characters, an android. This movie was to be the first of a wave of movies employing computer generated imagery. [5]
Futureworld, the sequel to Westworld, was released in 1976. A scene in Futureworld used a 3D model of a human hand, a model designed and built by Dr. Edwin Catmull while he was a graduate student at the University of Utah. [6] After graduation, he joined the New York Institute of Technology Computer Graphics Lab. Catmull and other researchers at the CGL helped to develop many of the advanced graphics techniques used in todays movies. In 1979, the group started working on the first feature length computer animated movie, The Works. The group worked for 3 years before releasing the first trailer at SIGGRAPH, the Association for Computing Machinery Special Interest Group in Computer Graphics, in 1982. Unfortunately, due to both technical and financial limitations, work on the movie was halted in 1986 and the film was never finished. [7]
George Lucas, a film director and producer, created a new computer graphics division at Lucasfilm in 1979. Dr. Catmull, along with other researchers from NYIT, were among the initial hires. The computer graphics group concentrated on 3D graphics, eventually developing a computer system for Disney and Industrial Light and Magic (ILM) called the Pixar Image Computer. In 1986, Steve Jobs, CEO of Apple Inc., purchased the computer graphics department from Lucasfilm. Pixar used their computer to develop a number of movie shorts to show off the capabilities of the system. Ultimately, however, Pixar stopped selling the computer due to slow sales.
Despite problems selling their Image Computer, Pixar was able to generate revenue by creating animated commercials for various companies. Pixar decided that animation was their strong suit and began pursuing an avenue for producing full-length animated films. Their earlier business dealings with Disney allowed them to sign a deal wherein Pixar would create a full-length film and Disney would market and distribute it. Pixar and Disney released the world's first full-length computer animated movie, Toy Story, in 1995. [8]
While Pixar was developing technology for cartoon rendering, other companies such as Triple I and ILM were developing technologies that could be used in traditional live-action movies. Perhaps one of the most famous “computer” movies, Tron, was released in 1982. Triple I helped to create approximately 15 minutes of computer animation that was used in the movie. [9] In the same year, ILM used fractals, a mathematical technique, to generate a landscaping sequence for the movie Star Trek II: The Wrath of Khan. [10]
ILM created the digital effects for Terminator 2 in 1991. Several of the sequences in the movie featured a liquid metal humanoid form transforming into several different characters. ILM had to create new techniques for creating realistic humanoid actions such as walking and running. [11]
At the turn of the century, computer graphics has reached a point where so-called hyper-realism is achievable. In 2001, Square Pictures, the computer-animated film division of the Square entertainment company, released Final Fantasy: The Sprits Within. The film featured a lead character, Aki Ross, who was entirely computer generated. Some of the special effects in the film included realistic modeling and animation of hair and facial features. [12]
Computer generated actors and models have been used in recent years for movies, commercials, and even print ads. These realistic characters are used in place of traditional actors for a variety of reasons. While it can take a tremendous amount of time to create a new “actor,” the benefits can easily outweigh the work. CGI actors are predictable and don't throw tantrums or have trouble remembering lines. Once the major design work has been completed, using a CGI actor is arguably as easy as posing an action figure. [13]
As technology progresses, it is inevitable that we will be able to create even more realistic characters, completely blurring the lines between real and imaginary. One can argue that we have already hit that point with movies such as Avatar, which feature entirely new species and civilizations created entirely out of pixels. But as brilliant as Avatar is, it still relies on human actors to serve as motion capture targets. Even the facial expressions used in Avatar are based on motion captured data from live actors. [14]
It seems, however, that we are quickly approaching a time when even real actors won't be necessary to create the latest movies and television shows. A time when technology will edge out high paid actors, replacing them with a hard drive full of bits. Bits that can be molded to any role, instantly, without the need to eat or sleep. It means we will have actors who can do all of their own stunts without fear of getting injured or requiring body doubles. In short, it means we can fulfill roles we have never been able to fill before, with relatively inexpensive labor.
Does this mean we will see a shift in the industry as actors move to fill new roles as voices, or even as writers or directors? Or will we see a battle between the real and the imaginary? As was seen in the automotive industry as robots took over human jobs, fear was everywhere. Will the movie industry see this as a negative move, or will they take a queue from workers who shifted from manual labor to technical jobs, in charge of the very robots that threatened to make them obsolete? Either way, technology is changing the way movies are made.
