The evolution of CGI led to the emergence of virtual cinematography in the 1990s, where the vision of the simulated camera is not constrained by the laws of physics. Advances in algorithms and electronics in flight simulator visual systems and CGI in the 1970s and 1980s influenced many technologies still used in modern CGI adding the ability to superimpose texture over the surfaces as well as transition imagery from one level of detail to the next one in a smooth manner. Early CGI systems could depict only objects consisting of planar polygons. Combined with the need to pair virtual synthesis with military level training requirements, CGI technologies applied in flight simulation were often years ahead of what would have been available in commercial computing or even in high budget film. Much of this reproduction had to do with believable visual synthesis that mimicked reality. Namely because the object of flight simulation was to reproduce on the ground the behavior of an aircraft in flight. Visual systems developed in flight simulators were also an important precursor to three dimensional computer graphics and Computer Generated Imagery (CGI) systems today. Prior to CGI being prevalent in film, virtual reality, personal computing and gaming, one of the early practical applications of CGI was for aviation and military training namely, the flight simulator. The first music video to use CGI was Dire Straits's award-winning " Money for Nothing" (1985), whose success was instrumental in giving the process mainstream exposure. Other early films that incorporated CGI include Star Wars: Episode IV (1977), Tron (1982), Golgo 13: The Professional (1983), The Last Starfighter (1984), Young Sherlock Holmes (1985) and Toy Story (1995). The first feature film to make use of CGI with live action in the storyline of the film was the 1973 film Westworld. The first feature film to use CGI as well as the composition of live-action film with CGI was Vertigo (1958), which used CGI in the opening credits of the film. ![]()
