What is Perspective (graphical)?
[[File:Lamentación sobre Cristo muerto, por Andrea Mantegna.jpg|thumb|''The Lamentation over the Dead Christ'' by [[Andrea Mantegna]]. The perspective in this painting is from an [[angle]] over the subject, towards his head as he is laying horizontally. The artist uses upward foreshortening to create the correct [[dimension]]s to match the angle.]] In [[graphic arts]], '''perspective''' is the representation of how an [[image]] is seen by the [[eye]]. It was first invented by [[Filippo Brunelleschi]]. It is about how the [[angle]] and [[distance]] of a [[3D|three-dimensional]] object is represented on a [[2D|flat]] [[surface]]. To create a real scene, objects are drawn smaller to show that they are farther away from the person looking at the artwork. The [[dimension]]s of an object are also drawn differently depending where the line of sight is. The size of an object's dimensions along the line of sight are usually drawn shorter than dimensions across the line of sight. This is called foreshortening, and is used to create the appearance of three dimensions on a flat [[surface]]. [[Landscape]] paintings have a horizon line. This line represents objects that are infinitely far away. They have shrunk, in the distance, like objects on the Earth's [[horizon]]. Changing the height of the [[horizon]] level changes the view point for the picture. A person lying on the ground and looking up would have a different view to a person on a ladder looking down.<ref>{{cite web |url=http://www.creativeglossary.com/art-perspective/eye-level.html |title=Eye Level Definition - Creative Glossary |first= |last= |work=creativeglossary.com |year=2011 |accessdate=1 May 2011 |archive-date=29 October 2010 |archive-url=https://web.archive.org/web/20101029030934/http://www.creativeglossary.com/art-perspective/eye-level.html |url-status=dead }}</ref> ==Basic concept== [[File:The importance of knowing perspective - Satire on False Perspective, by William Hogarth (1753).jpg|right|thumb|Satire on false perspective by [[William Hogarth|Hogarth]
