Low bandwidth animations transmitted via the internet (e.g. The frames may also be rendered in real-time as they are presented to the end-user audience. For pre-recorded presentations, the rendered frames are transferred to a different format or medium, like digital video. įor 3D animations, all frames must be rendered after the modeling is complete. The differences in appearance between key frames are automatically calculated by the computer in a process known as tweening or morphing. of the figure are moved by the animator on key frames. Then the limbs, eyes, mouth, clothes, etc. This technique is identical to how the illusion of movement is achieved with television and motion pictures.įor 3D animations, objects (models) are built on the computer monitor (modeled) and 3D figures are rigged with a virtual skeleton. To create the illusion of movement, an image is displayed on the computer monitor and repeatedly replaced by a new image that is similar to it but advanced slightly in time (usually at a rate of 24, 25, or 30 frames/second). Computer-generated animations can also allow a single graphic artist to produce such content without the use of actors, expensive set pieces, or props.
The target of the animation is sometimes the computer itself, while other times it is film.Ĭomputer animation is essentially a digital successor to stop motion techniques, but using 3D models, and traditional animation techniques using frame-by-frame animation of 2D illustrations.
Modern computer animation usually uses 3D computer graphics to generate a three-dimensional picture. The more general term computer-generated imagery (CGI) encompasses both static scenes ( still images) and dynamic images ( moving images), while computer animation only refers to moving images.
