KRS's Comment of 2004
Visual Perspective is broadly organized into two categories, Artistic and Scientific with numerous combinations of both. Both categories aim at achieving an illusion of three-dimensional space on a two dimensional area, i.e., a planar surface.
- This introduction does not explain what visual perspective is. It would be more helpful to know what visual perspective is, before knowing who uses it, or what categories it falls into. That kind of information should be included in the perspective (graphical) page. — Preceding unsigned comment added by YBorg13 (talk • contribs) 23:56, 11 May 2013 (UTC)
Within Artistic Perspective, artists use their intuition and artistic talent with artists’ materials to produce an illusion of three-dimensional space. Within Scientific Perspective, technically trained specialists use the principles of graphic projection and drafting materials (including computers) to produce an illusion of three-dimensional space. Further, it should be noted that computers may produce, in addition to images on a two-dimension area (computer screen), virtual space within the computer, “behind, into the screen” as it were. In the latter instance the computer operator may maneuver within this virtual, three-dimensional space at will. However, this application is separate from the subject of Scientific Perspective.
In my opinion, this should come in perspective (graphical), if there is a perspective(visual) separate from a perspective(graphical). Usually in technical drawing terminology we use the term "perspective view" or "perspective projection" to mean a representation of what the eye sees and not plain "perspective". If this is the case, then there is no need to call the perspective (graphical) page as that at all, it can be renamed as "perspective projection". KRS 19:57, 21 Feb 2004 (UTC)
- I concur. Author seems to confuse distinction between foreshortening and perspective projection........... Suggest discontinuing the page... Pat Kelso 09:10, Mar 22, 2004 (UTC)
Just checking on a bit of disambiguation cleanup - is the link to "Perspective" under "see also" of any real use, or can I either delete the link or make it a "for other uses of the term perspective..." type link. If I get no comments in the next few days I'll delete the link LeeG 23:05, 31 May 2006 (UTC)
The horizon is not at eye level all the time. If I climb a nearby mountain and look out over the sea it's significantly lower if I hold my head level. Where is the explanation for any of this?
- There is indeed much overlap. #KRS's comment of 2004 seems to be related to this, and may have been intended to motivate this distinction, but it appears that his distinction has not been carried through in the current articles. Interestingly, just when KBS and Pat Kelso were discussing this, Pat moved a large chunk to Graphical projection, which now provides another overlap. — Sebastian 22:13, 8 March 2013 (UTC)
- I think the subjects are sufficiently distinct to merit separate articles. Visual perspective describes a phenomenon that exists in the eye of an observer when looking at objects in space; it includes the apparently diminished size of distant objects (linear perspective) as well as aerial perspective. Graphical perspective is a set of conventions by which artists and designers represent this, typically on a two-dimensional surface. The trickery involved is comparable to that required when rendering the curved surface of the earth on a flat map. Despite overlap, the subjects probably should be developed separately, as cartography and map projection are. Ewulp (talk) 08:58, 9 March 2013 (UTC)
