Monocular Cues

Monocular cues deal with items that can be process with one eye. Relative size, texture gradient, aerial perspective, and linear perspective are the main components that make up monocular cues. In relative sizing, if two objects are roughly the same size, to object that looks the largest will be judged as being the closest to the observer. In texture gradient, when one is looking at an object that extends into the distance, the texture becomes less and less apparent the farther it goes into the distance. In aerial perspective, objects that are farther away seem to be blurred or slightly hazy due to atmosphere. Lastly, linear perspective incorporates the idea that parallel lines appear to meet as they travel into the distance. For example, the outer edges of a road seem to grow closer and closer until they appear to meet. The closer together the two lines are, the greater the distance will seem.
