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 ...
Motion features a floating semi-transparent window ("heads-up display", or HUD) which displays the most commonly altered parameters of the object or effect currently selected. This allows the user to make quick adjustments without having to search through palettes and menus. However, exact numerical values cannot be entered in this window.
Scrolling displays built up of individual tiles can be made to 'float' over a repeating background layer by animating the individual tiles' bitmaps in order to portray the parallax effect. Color cycling can be used to animate tiles quickly on the whole screen. This software effect gives the illusion of another (hardware) layer.
Computer animation is essentially a digital successor to stop motion techniques, but using 3D models, and traditional animation techniques using frame-by-frame animation of 2D illustrations. For 2D figure animations, separate objects (illustrations) and separate transparent layers are used with or without that virtual skeleton.
The artist is drawing on a transparent easel, onto which the film projector at the right is beaming an image of a single film frame. Rotoscoping is an animation technique that animators use to trace over motion picture footage, frame by frame, to produce realistic action.
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. When frame rate is a limiting factor, one smooth scrolling technique is to blur images during movement that would otherwise appear to "jump".
Frames 2–4 are smear frames, those being elongated inbetweens. In animation, a smear frame is a frame used to simulate motion blur. Smear frames are used in between key frames. [1] This animation technique has been used since the 1940s. [1] Smear frames are used to stylistically visualize fast movement along a path of motion. [2] [3] [4]
The Ken Burns effect is a type of panning and zooming effect used in film and video production from non-consecutive still images. The name derives from extensive use of the technique by American documentarian Ken Burns .
