Global Illumination
Global Illumination in lighting design means using calculations to show how light bounces around a space, not only from the main light source but from every surface it touches. This helps designers see how colors and materials will look in real life, because light reflects and spreads in many directions. Using Global Illumination in digital models helps predict how daylight or artificial light will fill a room, making it easier to choose the right materials and plan where to put lights for the best effect. This method can show soft shadows and bright spots that happen when light hits different textures or shapes, helping designers make spaces feel more natural and comfortable.
