What is one technique that Velazquez uses to create the illusion of dept In La's meninas?

In "Las Meninas," Velázquez employs linear perspective to create the illusion of depth. The placement of the figures and the converging lines of the room's architecture draw the viewer's eye into the space, leading to the background where the open doorway adds further depth. Additionally, the use of light and shadow enhances the three-dimensionality of the figures, contributing to the overall sense of depth in the composition.
