Animation traditionally is done by hand-drawing or painting successive frame of an object, each slightly different than the proceeding frame. In computer animation, although the computer may be the one to draw the different frames, in most cases the artist will draw the beginning and ending frames and the computer will produce the drawings between the first and the last drawing. This is generally referred to as computer-assisted animation, because the computer is more of a helper than an originator.
In full computer animation, complex mathematical formulas are used to produce the final sequences of pictures. These formulas operate on extensive databases of numbers that defines the objects in the pictures as they exist in mathematical space. The database consists of endpoints, and color and intensity information. Highly trained professionals are needed to produce such effects because animation that obtains high degrees of realism involves computer techniques from three-dimensional transformation, shading, and curvatures.
High-tech computer animation for film involves very expensive computer systems along with special color terminals or frame buffers. The frame buffer is nothing more than a giant image memory for viewing a single frame. It temporarily holds the image for display on the screen.
A camera can be used to film directly from the computer’s display screen, but for the highest quality images possible, expensive film recorders are used. The computer computers the positions and colors for the figures in the picture, and sends this information to the recorder, which captures it on film.
Sometimes, however, the images are stored on a large magnetic disk before being sent to the recorder. Once this process is completed, it is replaced for the next frame. When the entire sequence has been recorded on the film, the film must be developed before the animation can be viewed. If the entire sequence does not seem right, the motions must be corrected, recomputed, redisplayed, and rerecorded. This approach can be very expensive and time – consuming. Often, computer-animation companies first do motion tests with simple computer-generated line drawings before selling their computers to the task of calculating the high-resolution, realistic-looking images.

Why do people like to chew gum? Some people say they like the taste.(31)________say they can think better if they chew gum. Some people chew it when they have some boring work to do. Others chew gum when they are nervous.
Gum is a mixture of things. For many years gum companies made gum from chicle. Chicle is a natural gum from a tree in Mexico and Central America. Now companies use plastic and rubber made from petroleum (32)________of chicle.
Gum must be soft so that you can chew it. A softener keeps it soft. The gum company makes the softener from vegetable oil. A sweetener makes the gum sweet. The sweetener is usually sugar. Then the company (33)________the flavor.
Thomas Adams made the first gum from chicle in 1836. However , chewing gum was not new. The Greeks chewed gum from a tree (34)________2,000 years ago. Mayan Indians in Mexico chewed chicle. Indians in the Northeastern United States taught Europeans to chew gum from a tree there. People first made bubble gum in 1928. Children like to (35)________bubble with bubble gum. Some university students do too.
