Using the most advanced film technology to expand the influence of the animation industry in Hollywood is the basic feature that Pixar has insisted on since its debut 11 years ago, "Toy Story". Of course, this tradition will continue to be carried forward in "Cars."
In 2005, when Pixar was absent, the starlight of the animation industry was dim, forming a situation where stop-motion animation dominated the country. Now that Pixar has joined hands with Disney to make a grand appearance with the new work, it is the beginning of CG animation to take over control again. I don’t know if things are going to be reversed. Today, when computer technology can show even the finest hairs, 3D animations have been resurged, and they have begun to pay attention to the lives of the "iron sheet" characters whose painting techniques are a little rough, such as this film and last year's Blue Sky Studio. "The Adventures of Robots". However, the situation is by no means as simple as what we laymen have seen. The lighting debugging of this kind of all-metal character film is an important point. The absence of light means that the character will lack the texture of metal. Therefore, with the release of "Cars", it must be a brand new field achieved by "ray tracing" and "environmental rendering and rendering" technology. After experiencing toys, bugs, monsters, fish and superheroes, creating a world inhabited entirely by cars has become a new challenge for Pixar's skilled craftsmen. All the characters are made of metal shells, so the expressiveness of the characters can only be accurately refined through rich computer technology. It can be said that "Cars 2" is Pixar's first animation work using "ray tracing". Technology can help car characters and the environment they are in to be more authentic and credible. John Lasseter is still a master of "speaking with the truth", he requires the artist to find a way to restore all models of cars, even if it is an inconspicuous screw cap. More than 100 car roles have been mentioned. Therefore, the artists have done a lot of special tests for this purpose. In order to make the characters more realistic and at the same time enhance the entertainment of the story, they cleverly use the car tires to tell things and describe their functions to the limbs of adults, so that the car characters are not. While losing the inherent characteristics, it also possesses the corresponding humanity.
"Environmental rendering and drawing" is the most time-consuming process, which is also the root cause of Pixar's "bye" in 2005. Although in this work, John Lasseter chose the best programmers, and operated 3,000 computers at the same time to perform complex tasks-the time was more than four times faster than when rendering "The Incredibles" , But on average, the average rendering work for each frame is more than 17 hours. With such a complicated process to complete a nearly two-hour animated feature film, it feels terrifying to think about it.
