<P> Due to scheduling conflicts with other projects (Moore had to travel to different places such as London or New York, and Levi could only record on weekends for five hours once every six weeks), they did not necessarily record dialogue in the same order as in the final film . "(When I came in), maybe that sequence or scene had been recorded by Mandy (Moore) already, maybe it hadn't . We'd end up doing the same scene five times, depending," Levi said . After watching the finished film, Moore was disappointed because she felt that her voice sounded "shrill", while Levi thought that his performance sounded "incredibly nasally". </P> <P> The film was made using computer - generated imagery (CGI), although Tangled was modeled on the traditional look of oil paintings on canvas . The Rococo paintings of French artist Jean - Honoré Fragonard, particularly The Swing, were used as references for the film's artistic style, a style described by Keane as "romantic and lush ." To create the impression of a painting, non-photorealistic rendering was used . </P> <P> Glen Keane originally wanted the film to be animated using a traditional 2D animation process . However, Disney executives David Stainton and Dick Cook announced that they would only approve the film for production if it were created using the 3D computer graphics . In response to that demand, Glen Keane held a seminar called "The Best of Both Worlds", where he, with 50 Disney CGI artists and traditional artists, focused on the pros and cons of each style . After the meeting, it was decided that the film would be made in 3D CG animation, but in a way as to become an extension of the traditional 2D Disney "aesthetic", a term which referred to the naturalistic animation that conforms to the fundamental principles of animation as documented by Frank Thomas and Ollie Johnston in the book The Illusion of Life: Disney Animation . </P> <P> Due to limitations in computer technology, especially regarding attempts to capture the complexity of a human form, many basic principles of animation used in traditionally animated movies had been absent from earlier CGI films; but technological advancements have made it easier to blend the two, combining the strengths of each style . Keane stated repeatedly he was trying to make the computer "bend its knee to the artist" instead of having the computer dictate the artistic style and look of the film . By making the computer become as "pliable as the pencil", Keane's vision of a "three - dimensional drawing" seemed within reach, with the artist controlling the technology . Many of the techniques and tools that were required to give the film the quality Keane demanded did not exist when the project was started, and Walt Disney Animation Studios had to create them on their own . Keane said, "There's no photoreal hair . I want luscious hair, and we are inventing new ways of doing that . I want to bring the warmth and intuitive feel of hand - drawn to CGI ." </P>
