Editing Perspective (graphical) (section)

==Overview==
Linear or point-projection perspective works by putting an imaginary flat plane that is close to an object under observation and directly facing an observer's eyes (i.e., the observer is on a normal, or perpendicular line to the plane). Then draw straight lines from every point in the object to the observer. The area on the plane where those lines pass through the plane is a point-projection prospective image resembling what is seen by the observer.

Additionally, a central [[vanishing point]] can be used (just as with one-point perspective) to indicate frontal (foreshortened) depth.<ref>{{cite web |title=The Beginner's Guide to Perspective Drawing |url=https://www.thecuriouslycreative.com/topics/beginners-guide-drawing/perspective-drawing/ |website=The Curiously Creative |access-date=17 August 2019}}</ref>
