Computers have come a long way very fast since there start in the 1940's.  In
the beginning they were mainly used for keeping financial records by  banks and
insurance companies, and for mathematical computations by engineers and the U.S.
Military.

However, exciting new applications have developed rapidly in the last few years.
Two of these areas is Computer Graphics and sound.

Computer graphics is the ability of the computer to display, store and transmit
visual information in the form of pictures.  Currently there are two main uses
for this new ability.  One is in the creation  of Movies and the other in
Computer Games.  Computer visual information is also increasingly being used in
other  computer applications, such as photographic storage, and the Internet.

Computers can also store, transmit and play back sound.

When a picture or a sound is stored on a computer it said to be digitized.
There are two main ways of digitizing a picture.  One is by vector graphics.
Here the information in the picture is stored as mathematical equations.
Engineering drawing applications such as CAD (computer assisted device)  use
this method.  The other method is by bit mapped graphics. Here the computer
actually keeps track of every point in the picture and its description.  Paint
programs use this technique.  Drawing programs are usually vector mapped
programs and paint programs are usually bit mapped.

Computer sound is handled in two different ways.  The sound can  be described
digitally and stored as an image (wave format) of the actual sound or it can be
translated in to what is called midi format.  This is chiefly for music. In a
piano, for instance,  the information for what key to  hit, for how long ad at
what intensity is stored and retrieved.  This is kind of like the way and old
player piano worked.

Computer graphic applications in the beginning were developed on large computes.
The computer hardware and software were developed by  individuals and groups
working independently.

These projects were very expensive and carried on by large companies and
investment groups.  Applications which only a few years ago would have cost
millions of dollars, can now be run on a desk top computer with programs costing
under $100.

It is the purpose of this paper to research and examine several areas of
computer multimedia by using a typical application programs in that related area.

These areas are:
