Diepteperceptie en ruimtelijk zicht

Depth perception enables the perception of objects in three dimensions. It uses both binocular and monocular cues to create a sense of depth.

Binocular cues, which include convergence and binocular disparity, use slightly different images captured by each eye due to their positions to help perceive the world in three dimensions.

Convergence is the inward rotation of the eyes to focus on a single object, like a pencil, as it is brought closer to the eye.

As a pencil moves closer to the nose, the differences in images seen by each eye increase, a concept called Binocular disparity. Greater differences between images indicate a closer object, while almost identical images suggest a distant object.

Monocular cues, or pictorial depth cues, like linear perspective and texture gradient, create the illusion of depth in two-dimensional works.

Linear perspective makes distant objects appear smaller, making them seem farther away. Texture gradient shows the texture of surfaces, such as fields becoming denser and finer with distance.
