What is computer animation?
Computer animation is a general term for a type of visual digital display technology that simulates moving objects on the screen. Modern forms of computer animation have evolved from more primitive computer graphics in the last few decades, as great advances in computer technology have resulted in much more sophisticated imaging techniques. Modern computer animation can achieve dazzling results with three-dimensional figures that act against a three-dimensional background. As a result, it has largely revolutionized the film industry by reducing the costs associated with setting up film sets, hiring extras, and collecting props. Many of these physical objects can now be simulated using computer animation.
The simplest and earliest forms of computer animation simply moved objects on a screen in two-dimensional computer graphics animation. This type of technology is still common in animated GIF files, for example. Early 64-bit computer systems could achieve this type of animation, which gradually evolved into more sophisticated forms in which pre-drawn images were juxtaposed on moving backgrounds to simulate an elaborate animation role.
Today's computer animation, also known as computer-generated imagery (CGI) animation, uses three-dimensional processes in which digitally generated parts are placed on a conceptual 'skeleton' or other framework. CGI can refer to static or animated content, while computer animation specifically refers to the display of objects in motion.
