Per-Pixel Lighting

Per-pixel lighting is a technique used in computer graphics to determine how light interacts with surfaces on a pixel-by-pixel basis, rather than just averaging light across a larger area. This method allows for more realistic images by considering each pixel's position, texture, and surface properties when calculating how light reflects or refracts. As a result, it produces detailed highlights and shadows, enhancing the depth and clarity of 3D graphics in video games and animations, making them look more lifelike and visually appealing.
