Description: Light sources in computer graphics are crucial elements that simulate lighting in a three-dimensional environment. These sources are mainly classified into three types: point lights, directional lights, and spotlights. Point lights emit light in all directions from a single point, like a light bulb, and are ideal for simulating localized light sources. Directional lights, on the other hand, emit light in a specific direction, similar to sunlight, providing uniform illumination across a scene. Lastly, spotlights project a beam of light onto a specific area, creating a more dramatic and controlled lighting effect, like that of a projector. Each type of light source has unique characteristics that affect how objects in the scene are illuminated and how their colors and shadows are perceived. In graphics programming environments, these light sources are implemented through various functions and parameters, allowing developers to adjust the intensity, color, and position of the light to achieve realistic visual effects. Proper use of these light sources is essential for creating immersive and engaging environments in video games and graphic applications.
