ShuffyIosys (talk | contribs) Removed the table of GPUs that support HDR rendering for the following reasons: 1. It hasn't been updated in years. 2. It'll only keep growing now that GPUs are unlikely to not support HDR. 3. Which GPUs that support HDR rendering can be tied together given the information regarding which API introduced/supports it. |

'''High-dynamic-range rendering''' ('''HDRR''' or '''HDR rendering'''), also known as '''high-dynamic-range lighting''', is the [[Rendering (computer graphics)|rendering]] of [[computer graphics]] scenes by using [[computer graphics lighting|lighting]] calculations done in [[high dynamic range]] (HDR). This allows preservation of details that may be lost due to limiting [[

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 lightprobe data to provide realistic lighting solutions.
