  2. Temporal light artefacts - Wikipedia

    en.wikipedia.org/wiki/Temporal_light_artefacts

    Temporal light artefacts (TLAs) are undesired effects in the visual perception of a human observer induced by temporal light modulations. Two well-known examples of such unwanted effects are flicker and stroboscopic effect. Flicker is a directly visible light modulation at relatively low frequencies (< 80 Hz) and small intensity modulation levels.

    As users adjust to the experience, they see increasingly complex animated yantra-like patterns of color behind their closed eyelids (similar effects may be seen when travelling as a passenger in a car or bus; close your eyes as the vehicle passes through the flickering shadows cast by regularly spaced roadside trees, streetlights or tunnel ...

  4. Adobe After Effects - Wikipedia

    en.wikipedia.org/wiki/Adobe_After_Effects

    Adobe After Effects is a digital visual effects, motion graphics, and compositing application developed by Adobe Inc.; it is used for animation and in the post-production process of film making, video games and television production. Among other things, After Effects can be used for keying, tracking, compositing, and animation.

  5. Stroboscopic effect - Wikipedia

    en.wikipedia.org/wiki/Stroboscopic_effect

    If the modulation frequency is below the flicker fusion threshold and if the magnitude of the TLM exceeds a certain level, then such TLMs are perceived as flicker. Light modulations with modulation frequencies beyond the flicker fusion threshold are not directly perceived, but illusions in the form of stroboscopic effect may become visible ...

  6. Flicker fusion threshold - Wikipedia

    en.wikipedia.org/wiki/Flicker_fusion_threshold

    The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science , more specifically in the psychophysics of visual perception .

  7. Persistence of vision - Wikipedia

    en.wikipedia.org/wiki/Persistence_of_vision

    Impressions of several natural phenomena and the principles of some optical toys have been attributed to persistence of vision. In 1768, Patrick D'Arcy recognised the effect in "the luminous ring that we see by turning a torch quickly, the fire wheels in the fireworks, the flattened spindle shape we see in a vibrating cord, the continuous circle we see in a cogwheel that turns with speed". [8]

  8. Flicker (light) - Wikipedia

    en.wikipedia.org/wiki/Flicker_(light)

    In visual perception, flicker is a human-visible change in luminance of an illuminated surface or light source which can be due to fluctuations of the light source itself, or due to external causes such as due to rapid fluctuations in the voltage of the power supply (power-line flicker) or incompatibility with an external dimmer.

  9. Adobe Character Animator - Wikipedia

    en.wikipedia.org/wiki/Adobe_Character_Animator

    Adobe Character Animator is a desktop application software product that combines real-time live motion-capture with a multi-track recording system to control layered 2D puppets based on an illustration drawn in Photoshop or Illustrator.
