Shading is a technique used in visual arts and computer graphics to add depth and realism by manipulating light and shadow. In traditional art forms like drawing and painting, shading involves varying the intensity and direction of light sources to create shadows and highlights, giving the illusion of three-dimensionality. In digital art and graphics, shading is crucial for rendering realistic images, achieved through algorithms simulating light interaction with surfaces. Different shading techniques are employed to calculate pixel illumination, enhancing visual fidelity and realism in animations, video games, architectural renderings, and product designs. Mastering shading techniques allows artists and designers to imbue their work with depth, mood, and visual impact, enriching the viewer’s experience.
