Types of Animation
Two dimensional (2D) animation software adds movement and action to static images. These programs use either vector drawn or bitmapped images as objects. The motion of animation is perceived by the viewer from a series of frames. For the motion to appear smooth a minimum of 15 frames persecond (fps) is generally required.
There are two types of 2D animation, path & cel
Cel animation is based on a series of frames or cels in which the object is redrawn in each consecutive cel to depict motion. Cel comes from the word celluloid (a transparent sheet material) which was first used to draw the images and place them on a stationary background.
Figure below shows a set of eight cels that can be used to create an animation of a magician with his magic rod. The magician is a multiple-cel actor. Playing the cels in sequence will create the illusion of the magician jumping around.
