4.0 Charles Mirho Based on noise and turbulence theory, procedural textures in Microsoft Internet Explorer 4.0 enable realistic, natural animations by combining a single bitmap with mathematical equations. P eople like to watch things move.
Animation is the technique of creating the illusion of motion.
One approach is frame animation, in which a series of bitmaps are sequenced rapidly to provide the illusion of motion. Another technique is palette animation, in which the color palette of a single bitmap is manipulated over time to reveal interesting patterns that only become visible as the colors change. Both techniques have limitations. Furthermore, once the frames are created, the animation follows a predictable sequence from start to finish and then repeats itself. Palette animation has a similar limitation.
