Phong shading

Phong shading is a computer graphics technique used to make 3D objects look more realistic by simulating how light interacts with their surfaces. It calculates the color at each point on an object's surface based on light sources, surface material properties, and the viewer's position. By smoothly blending these calculations across the surface, Phong shading produces realistic highlights and subtle shading, giving a sense of depth and three-dimensionality. This method enhances visual detail without requiring excessive computational power, making objects in digital images appear more natural and visually appealing.
