Projective geometry

explains how an eye perceives the "real world"

Terraced perspective

a technique of drawing people at the back of a group higher up than those in the front

Vertical perspective

An artist would draw pairs of parallel lines place symmetrically on either side of the scene by lines that meet on the center line of the picture

Focused perspective

A cross section can give the same impression as the original item due to the corresponding points followed by light rays

Mathematical perspective

all lines through a given point in R^3

Diagonal vanishing point of the perspectivity

The point in which the images of all lines in a plane in some direction vanish

Deargues theorem

A 3D figure has properties that allow the points where the image meets the figure to be collinear

Projective point

A line in R^3 that passes through the origin
