What is modeling technique in art?

Modeling technique in art refers to the method of creating the illusion of three-dimensional form on a two-dimensional surface through the use of light and shadow. Artists achieve this by manipulating values and tones to suggest depth and volume, often employing techniques like chiaroscuro, which emphasizes contrasts between light and dark. This technique can be applied in various mediums, including painting, drawing, and sculpture, to enhance the realism and dimensionality of the artwork.
