Revision 3888565 of "Perspective (viewpoint)" on enwiki

'''Perspective''' is a broad term that has the following disinctive, albeit closely related meanings.

*[[Perspective (visual)]] is an aspect of [[visual perception]] of space and objects that depends on the point of view from which they are perceived. For example, the parallel lines of a railway track are perceived by the eye as meeting at a distant point. 

*[[Perspective (graphical)]] as [[graphics|graphic]] [[representation]] of objects perceived by the eye denotes a technique of representing three-dimensional objects on a planar surface with the aim of retaining the illusion of three-dimensional space, i.e., a way to imitate the [[Perspective (visual)|visual perspective]]. 

*[[Perspective (cognitive)]] in theory of [[cognition]] is the choice of a [[context]] or a [[reference]] (or the result of this choice) from which to sense, categorize, measure or codify experience, typically for comparing with another. One may further recognize a number of subtly distinctive meanings, close to those of [[Point of view]], [[Weltanschauung]], [[paradigm]].

The key idea that unifies all these types of perspective is that the human experience is tied closely with the [[point of view]] from which the perceiving occurs.
