Animation – The illusion of movement.
Animation is the art by which two-dimensional drawings or inanimate objects are turned into moving visual representations of two-dimensional (2D) or three-dimensional (3D) life. Computer animation uses computer hardware and software to make the animation process easier and faster. Although there used to be clear divisions among cartoon and feature film animation, visual effects, gaming software, 3-D animation, and GIF animation, these related forms of animation now often overlap.
Animation can be described as the creation of the illusion of motion through a rapid sequence of still images. Although the quality of the original images is important, equally important is the quality of the sequence through which action, character, and story development are portrayed. There must be a coherent pattern to the action. A common story structure introduces characters, a source of conflict, the development of this conflict, a climax, and finally a resolution. But an animated story can also be more fluid, including the creation of forms or simple images, some interaction of them, and then a transformation or transmutation , such as a smiley face turning into a frown or dissolving into the background.
