What is the meaning of modeling in art?

Modeling in art refers to the technique of creating the illusion of three-dimensional form on a two-dimensional surface through the use of light and shadow. It involves manipulating tones and colors to give depth and volume to shapes, making objects appear more lifelike. This technique is commonly used in drawing, painting, and sculpture to enhance realism and convey texture. Ultimately, modeling helps artists portray the physical presence and dimensionality of their subjects.
