High-dynamic-range rendering

<p>High-dynamic-range rendering (HDRR or HDR rendering), also known as high-dynamic-range lighting, is the <a href="/facts/Rendering_(computer_graphics)/YYxfnmAq">rendering</a> of <a href="/facts/Computer_graphics/lapBE8wv">computer graphics</a> scenes by using <a href="/facts/Computer_graphics_lighting/kHshvyKY">lighting</a> calculations done in <a href="/facts/High_dynamic_range/n4yFQ5tG">high dynamic range</a> (HDR). This allows preservation of details that may be lost due to limiting <a href="/facts/Contrast_ratio/PQG4mJrS">contrast ratios</a>. <a href="/facts/Video_game/vmTdNASJ">Video games</a> and <a href="/facts/Computer_animation/rPW63nm0">computer-generated movies and special effects</a> benefit from this as it creates more realistic scenes than with more simplistic lighting models. HDRR was originally required to <a href="/facts/Tone_mapping/AJU0QdzE">tone map</a> the rendered image onto <a href="/facts/Standard-dynamic-range_video/URDwL3DT">Standard Dynamic Range</a> (SDR) displays, as the first <a href="/facts/High-dynamic-range_television/jzRH1mFe">HDR capable displays</a> did not arrive until the 2010s. However if a modern HDR display is available, it is possible to instead display the HDRR with even greater contrast and realism.
</p><p>Graphics processor company <a href="/facts/Nvidia/8QfCgqbu">Nvidia</a> summarizes the motivation for HDRR in three points: bright things can be really bright, dark things can be really dark, and details can be seen in both.
