Computer MultimediaComputers have come a long way very fast since there start in the 1940s. Inthe commence they were mainly social occasiond for keeping financial records by banks andinsurance companies, and for mathematical computations by engineers and the U.S.Military.However, exciting new acts have developed rapidly in the survive few years.Two of these areas is Computer Graphics and sound.Computer graphics is the ability of the computer to display, store and transmitvisual information in the form of pictures. soon there are two main usesfor this new ability. One is in the creation of Movies and the other inComputer Games. Computer visual information is similarly increasingly being used inother computer applications, such as photographic storage, and the Internet.Computers female genital organ 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 support device) usethis method. The other method is by bit mapped graphics. Here the computeractually keeps track of every point in the picture and its description. Paintprograms use this technique. Drawing programs are usually vector mappedprograms and paint programs are usually bit mapped.Computer sound is handled in two different ways. The sound can be describeddigitally and stored as an image (wave format) of the actual sound or it can betranslated in to what is called midi format. This is chiefly for music. In apiano, for instance, the information for what key to hit, for how long ad atwhat intensity is stored and retrieved. This is kind of like the way and oldplayer piano worked.Computer graphic applications in the beginning were developed on large-mouthed computes.The computer hardware and software were developed by individuals and groupswo rking independently.These projects were very expensive and carried on by large companies andinvestment groups. Applications which only a few years ago would have costmillions of dollars, can now be run on a desk top of the inning computer with programs costingunder $100.It is the purpose of this paper to research and examine several areas ofcomputer multimedia by using a typical application programs in that related area.These areas arePaint Programs - Photo Finish -Zsoft3d Rendering Programs - 3d f/x - AsymetrixAnimation Programs - Video Artist - fall uponMorphing Programs - Video Artist - RevealSound Recording Programs - MCS music rack - LogitechMidi Recording Programs - Midisoft recording Session - Logitech
