Computer animation is the art of making pictures move through the use of computers.
This is a subfield computer graphics and animation.

The more that is created by 3D computer graphics, although 2D computer graphics are still widely used for low bandwidth and faster real-time rendering needs.

Occasionally the target is a computer animation itself, but sometimes other media target, like a movie.

This is also concerned to as CGI (Computer-generated imagery or computer-generated imaging), especially when used in the movie. To create the illusion of movement, an image displayed on the computer screen then quickly replaced with a new image similar to the previous image, but shifted slightly.

This method is identical to how the illusion of movement is achieved by television and film. Computer animation is essentially a digital successor to the art of stop motion animation of 3D models and frame-by-frame animation 2D illustration.

For 3D animations, objects (models) are rested on the computer monitor (model) and the characters who put 3D virtual frame.

2D animation for images, objects that are separated (illustrations) and separate transparent layers are used, with or without a virtual skeleton.

Then the hands and feet, eyes, mouth, clothes, etc.

from the image driven by the key animator on the frame.

The difference of opinion in visual aspect between key frames are automatically calculated by the computer in a process known as Tweening or morphing.

Eventually, animation is provided. For 3D animation, every frame must be given after the model completed.

2D vector animation, skeleton key delivery process illustration process, while the frame tweened translated as required.

Pre-recorded presentations, the frame will be transferred to a different format or medium, like film or digital video.

Frames can also be provided in real time as delivered to end-user audience.

Low bandwidth animations transmitted through the Internet (eg

2D Flash, X3D) often use software on the computer end-users to create real-time as an alternative to streaming or pre-loaded high bandwidth animations ..
