Barrier-grid animation or picket-fence animation is an animation effect created by moving a striped transparent overlay across an interlaced image. The barrier-grid technique originated in the late 1890s, overlapping with the development of parallax stereography (Relièphographie) for 3D autostereograms. The technique has also been used for ...
Parallax scrolling is a technique in computer graphics where background images move past the camera more slowly than foreground images, creating an illusion of depth in a 2D scene of distance. [1] The technique grew out of the multiplane camera technique used in traditional animation [ 2 ] since the 1930s.
The two keys are primarily used to scroll up or down in documents, but the scrolling distance varies between different applications. In word processors, for instance, they may jump by an emulated physical page or by a screen view that may show only part of one page or many pages at once depending on zoom factor.
Scrolling may take place in discrete increments (perhaps one or a few lines of text at a time), or continuously (smooth scrolling). Frame rate is the speed at which an entire image is redisplayed. It is related to scrolling in that changes to text and image position can only happen as often as the image can be redisplayed.
Parallax scrolling, a scrolling technique in computer graphics, wherein background images move by the camera slower than foreground images, creating an illusion of depth; Rear projection effect, an in-camera cinematic technique in film production for combining foreground performances with pre-filmed backgrounds
Billboards and other electronic signs use apparent motion to simulate moving text by flashing lights on and off as if the text is moving.. The term illusory motion, or motion illusion or apparent motion, refers to any optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts, object shapes, and position.

Moving panoramas were achieved by taking the long, continuous painted canvas scene and rolling each end around two large spool-type mechanisms that could be turned, causing the canvas to scroll across the back of a stage, often behind a stationary scenic piece or object like a boat, horse, or vehicle, to create the illusion of movement and ...
In dynamic layout, text elements move in relation to one another. Letters and words may move away from one another on a 2D plane, or in three-dimensional space. Likewise, scrolling typography can scroll across the flat screen, or can appear to recede or advance. An iconic example is the Star Wars opening crawl inspired by the Flash Gordon serials.
