What convention that Italian High Renaissance painters often used to create the illusion of depth?

Italian High Renaissance painters commonly used the technique of linear perspective to create the illusion of depth in their artworks. This method involves the use of a vanishing point on the horizon line, where parallel lines converge, drawing the viewer's eye into the composition. Additionally, they employed techniques such as chiaroscuro and atmospheric perspective, which further enhanced the three-dimensionality by manipulating light and color to suggest distance. These conventions collectively contributed to the realistic portrayal of space in their paintings.
