  2. Computer graphics lighting - Wikipedia

    en.wikipedia.org/wiki/Computer_graphics_lighting

    Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity.

    60 fps typically, some can do 120 fps; internally, display refreshed at e.g. 480 or 600 fps [20] 60 fps typically. Up to 480 fps. [21] Flicker: Perceptible on lower refresh rates (60 fps and below) [22] Depends; in 2013 most LCDs used PWM to dim the backlight [23] However, since then many flicker free LCD computer monitors were introduced. [24]

  4. Bloom (shader effect) - Wikipedia

    en.wikipedia.org/wiki/Bloom_(shader_effect)

    Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...

  5. Flicker (screen) - Wikipedia

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

    Flicker is necessary for a film-based movie projector to block the light as the film is moved from one frame to the next. The standard framerate of 24 fps produces very obvious flicker, so even very early movie projectors [example needed] added additional vanes to the rotating shutter to block light even when the film was not moving. Most ...

  6. Refresh rate - Wikipedia

    en.wikipedia.org/wiki/Refresh_rate

    In the case of filmed material, as 120 is an even multiple of 24, it is possible to present a 24 fps sequence without judder on a well-designed 120 Hz display (i.e., so-called 5-5 pulldown). If the 120 Hz rate is produced by frame-doubling a 60 fps 3:2 pulldown signal, the uneven motion could still be visible (i.e., so-called 6-4 pulldown).

  7. Dolby Vision - Wikipedia

    en.wikipedia.org/wiki/Dolby_Vision

    Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. [1] [2] [3] It covers content creation, distribution, and playback.[1] [4] [5] [6] It includes dynamic metadata that define the aspect ratio and adjust the picture based on a display's capabilities on a per-shot or even per-frame basis, optimizing the presentation.

  8. High-dynamic-range rendering - Wikipedia

    en.wikipedia.org/wiki/High-dynamic-range_rendering

    These two papers laid the framework for creating HDR light probes of a location, and then using this probe to light a rendered scene. HDRI and HDRL (high-dynamic-range image-based lighting ) have, ever since, been used in many situations in 3D scenes in which inserting a 3D object into a real environment requires the light probe data to provide ...

  9. Variable frame rate - Wikipedia

    en.wikipedia.org/wiki/Variable_frame_rate

    Variable frame rate (or VFR) is a term in video compression for a feature supported by some container formats which allows for the frame rate to change actively during video playback, or to drop the idea of frame rate completely and set an individual timecode for each frame.
