What are monocular and binocular depth cues?

Binocular depth cues require both eyes. Retinal disparity is the slight difference between images each eye receives because of their different positions, which the brain uses to judge distance. Convergence is the inward turning of eyes for near objects. Monocular depth cues work with one eye. Relative size assumes smaller images are farther away. Interposition or overlap means a closer object blocks a farther one. Linear perspective shows parallel lines converging in the distance. Texture gradient shows finer texture at greater distances.
