Talk:Vanishing point

Images
The image at right strikes me as a better illustration: it shows the people-mover at Frankfurt International Airport. I thought there might be too much investment in the current image to attempt to replace it. What do people think? --Wetman 23:59, 2 August 2007 (UTC)


 * I don't want to toot my own horn here, since I took the airport photo, but the current image really doesn't illustrate this visual phenomenon too well. I'm sure we can find much sharper images than the one I took, but until someone does, I'm going to be a bit bold and include it the article.

A five vanishing point perspective illustration is needed. Barnabas Szabolcs —Preceding unsigned comment added by 152.66.83.7 (talk) 15:52, 26 March 2009 (UTC)

Driving
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:
 * Vanishing points can also refer to the point in the distance where the edges of the roadway appear to converge. Movement of the vanishing point can help assess the upcoming curves in the road. If the vanishing point moves towards you or to your sides, the curve radius is reducing, so speed should be reduced. If the vanishing point moves away from you or comes to center, the curve is straightening.

This Talk space is available for anyone that might want to discuss application of the Vanishing point concept to driving.Rgdboer (talk) 22:03, 6 July 2013 (UTC)

Vanishing Lines
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. — Preceding unsigned comment added by 128.86.177.160 (talk) 09:39, 8 June 2017 (UTC)

Development and history?
Might be useful to add a section on the development of the concept (e.g. Alberti's De Pictura), to put it in a historical context. Bookgrrl holler/ lookee here 14:01, 7 October 2017 (UTC)
