The FLIP BOOK
The flip book is the manual way
you can create the illusion of animation. It is the foundation of
animation in motion pictures, computer generated gif animations, and
flash animations
The flip book consists of a
series of pages bound together which contain pictures. each picture
has a subtle differnce from the previous. As the user flips through
the book at a fast rate, the users eye catches the change and brain
interprets it as motion. If you go through the flip book slowly, the
subtle changes in the image my be nearly unperceivable.
The Motion Picture Movie is a
series of slides with slight differences per frame, and are played
through a projector at a fast enough rate so the user percieves
motion. The giff animation is similar in that it is a series of
images arranged into a sequence that is played at a set rate, to
simulate motion.
The Sprite: A sprite is a
simple graphic that moves over a larger non moving image. Using a
simple "sprite" animation, you can set up the sequential images side
by side. Here you can see the image going up and down through the
animation sequence..

<=
If you were to flip through them as in the old flip book you would
hold the book so that you could flip the pages fast.
If
you speed up the flip book you will perceive a more continuous
motion. =>
Hence you can see that an
animation is a series of images with very slight differences to
result in a perception of motion when viewed in fast succession.
