The image at right strikes me as a better illustration: it shows the people-mover atFrankfurt International Airport. I thought there might be too much investment in the current image to attempt to replace it. What do people think? --Wetman23:59, 2 August 2007 (UTC)[reply]
A five vanishing point perspective illustration is needed. Barnabas Szabolcs—Precedingunsigned comment added by152.66.83.7 (talk)15:52, 26 March 2009 (UTC)[reply]
Curves do not have vanishing points, only lines have them and they share with their parallels. The following text was removed, being unreferenced, and misleading:

In the section on vanishing lines the article states that "All vanishing lines end at the horizon line". This seems to be incorrect. According to my understanding, a vanishing line is defined as the line at which the projections of two parallel planes intersect. Thus, while any two planes that are parallel with the ground plane will intersect on the horizon line, any two parallel planes that are not also parallel with the ground plane will produce a vanishing line that is not on the horizon. To take one example, in a linear perspectival representation of a cube, the top of the cube and the bottom of the cube both sit on planes that are parallel with the ground plane, if these two planes are projected backwards they will intersect on the horizon line, however the left hand side of the cube and the right hand side of the cube sit on parallel planes that are perpendicular to the ground plane (they are vertical planes) and if these two planes are projected backwards until they intersect they will form a vanishing line that is vertical.
My understanding of the concept of the "vanishing line" comes mainly from the French wikipedia article for the "ligne de fuite":https://fr.wikipedia.org/wiki/Ligne_de_fuite
This article seems to suggest that while any two parallel lines meet at a vanishing point, or "point de fuite", any two parallel planes meet at a vanishing line, or "ligne de fuite". Just as vanishing points are normally on the horizon line but can in theory lie anywhere, vanishing lines tends to be contiguous with the horizon line, but they too can lie anywhere else.— Precedingunsigned comment added by128.86.177.160 (talk)09:39, 8 June 2017 (UTC)[reply]
Might be useful to add a section on the development of the concept (e.g. Alberti'sDe Pictura), to put it in a historical context.Bookgrrlholler/lookee here14:01, 7 October 2017 (UTC)[reply]
