Perspectivity edit

Latest comment: 3 years ago2 comments2 people in discussion

I don't think the mathematical term should be either the primary topic for this dab, or the root that the other articles are sub-listed under. I'd consider readers would be better served with the visual perspective not being so relegated. What do others think? Widefox; talk 11:01, 10 April 2014 (UTC)Reply

I agree, and try to explain.

Question1: which disambiguation in the first position?
"Perspectivity" was introduced (10:07, 10 January 2014‎ D.Lazard) with the comment "a geometrical concept which models and explains all the topics in this section", as the reason for the top position; today 2020 substituted by "the formation of an image in a picture plane of a scene viewed from a fixed point, and its modelling in geometry" (may be too long), that don't give reason for first place. More, I think it would be nice to have the same order in the section title and in the list.

Question2: Title of the section. Two options: "Vision and mathematics", or "Vision, graphics, mathematics".
I prefer to add "graphics", because independent from the others, and because one of the disambiguation link is so named. I prefer "Vision, graphics, mathematics", no "and", 3 terms equally separated to express same relevance; instead of "Vision, graphics and mathematics" which may subtend the relation between the first two with the last one.

I suggest for the section:
Vision, graphics, mathematics

Vue d'optique or perspective view, a genre of etching popular during the second half of the 18th century and into the 19th
Perspective (graphical), representing the effects of visual perspective in graphic arts
- Aerial perspective, the effect the atmosphere has on the appearance of an object as it is viewed from a distance
- Perspective distortion (photography), the way that viewing a picture from the wrong position gives a perceived distortion
Perspective (geometry), a relation between two geometric figures, one representing the other with the perspective rules
- Perspectivity, a geometric model on a picture plane of a figure viewed from a fixed point
- Perspective transform, seen as one of the 3D projections
