It was made by means of computer animation computers were used to create moving (animated) objects. There are two types of computer animation: 2D computer animation (two-dimensional), used with the use of computers with low hardware bandwidth, 3D computer animation (three-dimensional). Computer animation is sometimes also called, especially in the film industry, CGI (Computer Generated Imagery. The motion created on the computer consists in generating the image one by one, with each subsequent image slightly different in position from the previous one. Computer animation is derived from the traditional animation of stationary 3D objects, such as puppets, or stationary 2D objects, such as flat illustrations.
The computer animator first creates a three-dimensional model of the object, which then receives a virtual skeleton. Moving parts such as lips or eyes are animated by creating consecutive frames of animation. Any differences between these image manipulation service frames are computed by a computer that uses morphing and tweeting for the process. The final step in creating a computer animation is rendering. In 3D animation, only keyframes are rendered, and intermediate frames only as needed. It is also possible to render in real time. An example can be any Flash animations which, thanks to the use of software installed on the computer, render the animations in real time using a low bandwidth link.

How is it that the human eye perceives the animation of an object? For this to work, the animation frames must appear one after another with a frequency of at least 12 times per second. Above 70 times per second, the human brain will not pick up any changes - the animation will be just as fluid. Below 12 frames per second makes the animation choppy and unnatural. Computer animation is widely used in the film industry. The most famous example is "Toy Story", where, for example, to animate the main character, cowboy Woody, it was created thanks to 700 variable animations, 100 of them concerned his face.
