What is the role of shadow in three-dimensional art?

The role of shadow in three-dimensional art significantly contributes to creating the illusion of depth and volume. Shadows are essential in defining the contours and forms of objects, helping viewers perceive the three-dimensionality of the artwork. By casting shadows, artists simulate how light interacts with surfaces, which provides a sense of realism and spatial relationships within the piece.

Without shadows, objects could appear flat and two-dimensional, lacking the necessary cues that indicate their position in space. Thus, skillful use of shadow enhances the dimensionality of the artwork, drawing the viewer's eye and guiding their understanding of the forms being represented.

Although color, detail highlighting, and simplifying shapes can also play vital roles in art, they don't primarily focus on the critical function that shadows serve in establishing depth and volume in three-dimensional work.
