What is the Difference Between Shading and Lighting in Computer Graphics?
In computer graphics, shading and lighting are two related but distinct concepts. Lighting refers to the way that light interacts with objects in a scene, while shading refers to the way that the light is rendered on the object’s surface. In other words, lighting determines how much light is present in a scene, while shading determines how that light is distributed across the object’s surface. Shading takes into account factors such as the object’s material properties, texture, and geometry, as well as the direction and intensity of the light sources.
The difference between shading and lighting is important, as it allows computer graphics artists to control the visual appearance of their scenes with greater precision. By adjusting the lighting, artists can create a range of moods and atmospheres, from bright and cheerful to dark and ominous. By adjusting the shading, artists can create a range of detailed and realistic surface effects, from smooth and reflective to rough and textured.
