Fantasy, fiction, and horror would not be capable of coming to life without the aid of animation. That is, they wouldn't be as greatly enhanced as they are today. Animation has helped narrow the gulf between trivial artistic images and mathematics on the big screen. The techniques needed in order to use this type of imagery are rendering in comparison to past generations.
The Matrix, a recently popular series, solely survives on the use of computer animation to make the fictional images become more realistic. These images appeal to the audience as something fascinating and new. This is true because their brains are easily deceived by a lifetime of exposure to reality.
The block of color going off in a film immediately causes an identical block nearby to switch on resulting in the appearance of motion. Art and Math are linked to this in the way that artists who use computers for design have come to appreciate the mathematical equations that describe geometric shapes in each step.
Computer animated images are in the eye of the beholder. Nothing on the movie screen ever really moves; it is just dots changing color. Until recently, computers weren't capable of displaying pictures on the screen rapidly enough to stimulate this motion. Although it can be accomplished, the best results require special hardware.
Overall, animation can greatly improve the appearance of a film, and the types of critiques it can set. Particular movies in the fantasy, sci-fi, and horror realm would simply be ineffective without the use of animation. As the audience watches in contempt, the heroine slashes the emperor's head to signal the end of the film. Credits please!.
