4. Computer graphics lighting - Wikipedia

   en.wikipedia.org/wiki/Computer_graphics_lighting

   Without lighting models, replicating lighting effects as they occur in the natural world would require more processing power than is practical for computer graphics. [14] This lighting, or illumination model's purpose is to compute the color of every pixel or the amount of light reflected for different surfaces in the scene. [15]

It became widely used in video games after an article on the technique was published by the authors of Tron 2.0 in 2004. [1]
