  3. Computer Graphics: In computer graphics, shading is the process of adding color and darkness to a 3D model to simulate the way light interacts with the surface of an object. This is typically done using algorithms and lighting models to calculate the color at each point on the surface of the object.

  7. Welding: In welding, shading refers to the use of a welding helmet or other protective eyewear to shield the eyes from the intense light emitted during the welding process.
