Point lights are a type of light source that emits light uniformly in all directions from a single point. They are often used in various applications, such as in 3D graphics and theater lighting, to create a specific ambiance or highlight certain areas. Point lights can simulate natural light sources, like light bulbs or candles, providing a realistic effect in visual environments. In computer graphics, point lights are defined by their position and intensity. They do not have a specific direction, which means they illuminate objects around them equally. This characteristic makes them ideal for creating soft shadows and enhancing the overall visual appeal of a scene.
