perspective 

One of the cues to perception of the third dimension induced by a graphic representation on a plane, as in a drawing, or as a monocular cue, such as aerial perspective or linear perspective. (Fig. P8). See depth perception.
aerial perspective Perspective influenced by the state of clarity of the atmosphere. Far away objects appear less distinct and desaturated in colour due to the diffusion of light by the air in between the object and the eye. However, a very pure atmosphere may lead to underestimation of the distance of objects as they retain their distinctness and colour in this case. Aerial perspective is used by artists who soften and blur the colour and outlines of objects that they wish to appear as far away. See shadow.
geometrical perspective See linear perspective.
linear perspective Perspective conveyed by drawing images in different sizes. For example, parallel lines receding into the distance are made to converge. (Fig. P8) Syn. geometrical perspective.
