Animation is a type of optical illusion. It involves the appearance of motion caused by displaying still images one after another. Often, animation is used for entertainment purposes. In addition to its use for entertainment, animation is considered a form of art. It is often displayed and celebrated in film festivals throughout the world. Also used for educational purposes, animation has a place in learning and instructional applications as well. Cartoon animation is often considered to be animation in its classic form. The animated cartoon made its debut in the early part of the 20th century and calls for the use of 24 different drawings per second. In traditional animated cartoons, frames are hand drawn.

There are four basic techniques to be used in animation. These are: • Drawn animation • Cut-out animation • Model animation or stop motion animation • Computer animation or computer generated imagery (CGI) (1) Drawn animation-- Drawn animation, also termed as traditional animation and classical animation, is the oldest and historically the most prevalent form of animation. In a traditionally-animated cartoon, each frame is drawn by hand. This encloses any form, where one drawing is put back by another in a progression. Each drawing is somewhat unusual from the one which is placed before. Animated films are made up of thousands of drawings, depicted on screen very rapidly one after the other. It works in the same manner as the flip book does.
