{{short description|Simulation of light in computer graphics}}

'''Computer graphics lighting''' isencompasses the collectionrange of techniques used to simulate light inwithin [[computer graphics]] scenes. WhileThese methods vary in [[lightingcomputational complexity]], techniquesoffering offerartists flexibility in theboth level ofvisual detail and functionality available, they also operate at different levels of computational demand and [[Computational complexity|complexity]]performance. Graphics artistsprofessionals can chooseselect from a varietywide array of [[light sourcessource]]s, models[[lighting model]]s, [[shading]] techniques, and effects to suitmeet the needsspecific requirements of each applicationproject.

===HDRI===

HDRI stands for High dynamic range image and is a 360° image that is wrapped around a [[3D modeling|3D model]] as an outdoor setting and uses the sun typically as a light source in the sky. The [[Texture mapping|textures]] from the model can reflect the direct and [[Shading#Ambient lighting|ambient light]] and colors from the HDRI.<ref>{{cite web | url=https://visao.ca/what-is-hdri/#:~:text=High%20dynamic%20range%20images%20are,look%20cartoonish%20and%20less%20professional. | title=What are HDRI images? | date=13 January 2021 }}</ref>
