Unformatted text preview: nds. Hence animation files require much more storage space than graphic files involving a single image. Moreover, to play an animation clip stored in a file on a secondary storage device like hard disk, it should be possible to read the data at the required rate and transfer it through the bus to the frame buffer to display it on the monitor. Hardware Requirements for Animation Computer animation generally involves the following hardware devices: 1. Image generation tools and devices such as scanners, digital camera, and video capture board interfaced to some standard video source like video camera or video cassette recorder (VCR) are used to generate images to be used in animation. 2. Computer monitors with image display capability (described in the previous section) is the minimum requirement for outputting (displaying) animation. In addition, multimedia computer systems capable of handling animation also require a graphics accelerator board that not only controls the resolution and number of colors of display, but also speeds up the refresh rate. Refresh rate is the time taken to paint the computer screen with a new image frame replacing the previous image frame. Increased speed due to the use of graphics accelerator board smoothes out the movement (avoids flickering of animated sequences) because subsequent frames that make up the animation can be displayed more quickly. Software Requirements for Animation In addition to the above listed tools and devices, the following capabilities are highly desirable in a multimedia computer system with animation facility: 1. Animation creation software. This software allows the user to create animation sequences from scratch by using a mouse and various simple objects such as lines, circles and polygons with various supporting colors. For example, an animation sequence to illustrate bouncing of a ball can be created as follows: - select a circle object and fill it with red color; - then start the recorder of the animation creation software; - then select the colored circle and drag it around the screen using a mouse, recording several positions f...
