  Perspective (graphical) - Wikipedia, the free encyclopedia
Table of Perspective, 1728 Cyclopaedia Figure 1, with rays of light travelling from the viewer's eye, through the picture plane, and to the object, is the basis for graphical perspective.
Perspective (French: perspective from Latin perspicere, to see clearly) in the graphic arts, such as drawing, is an approximate representation on a flat surface (such as paper) of an image as it is perceived by the eye.
Perspectives consisting of many parallel lines are observed most often when drawing architecture (architecture frequently uses lines parallel to the x, y, and z axes).

 Talk:Perspective (graphical) - Wikipedia, the free encyclopedia
Reverse Perspective is often the term used to describe the condition wherein the station-point is located between the picture plane and the object of projection.
Perspective can be drawn in an instinctive way (as in the visual fine arts such as painting, sketching, etching, etc.) as well as in a quantified, technical way (technical graphics using drafting instruments).
It is widely held that perspective as a means of graphic representation was discovered by Brunelleschi during the Renaissance period.

This display would combine graphical objects, such as a model of the telerobot, and real objects which are visible in a video display, such that they appear to the observer to exist in the same three dimensional space.
The judgement of relative depth between a computer graphic object and a real object when they are combined in a single display would require that the various depth cues remain consistent across the graphics portion of the display and the video portion of the display (real display).
The SG is composed of two different graphic images of the same graphical model taken from different viewpoints, which are meant to be viewed correspondingly by the left eye and the right eye of the viewer.

In perspective the horizon line refers to the line where the sky and earth seem to meet; it is on this line that the vanishing point is located.
The scientific principles of perspective were first laid down, using mathematics and close observation, during the Renaissance period.
The rules of perspective were first applied to art by the 15th-century Italian painter Masaccio, who used slanted lines to make objects appear to extend back into space in his paintings; the technique was initially discovered by a contemporary, the architect Filippo Brunelleschi.

 Perspective (graphical) -   (Site not responding. Last check: 2007-10-08)
Perspective works by representing the light that passes from an object, through an imaginary rectangle (the painting), and to the viewer's eye.
Each painted object is a flat, scaled down version of the object on the other side of the window, but because it lies on a straight line from the viewer's eye to the object, there is no way (sans depth perception) to tell the difference.
Since perspective is strictly observed most often only when drawing architecture, and architecture typically uses lines parallel to the x, y, and z axes, it is rare to see more than three vanishing points.

By exploiting the binocular, perspective, and size constancy depth cues, the graphical model of the telerobot is positioned interactively by the operator, relative to the objects visible in the stereovideo image.
It was observed that to reduce bias in depth, the graphical gripper fingers should be drawn as fully rendered polygon whose hue, saturation, and brightness matches those of the object with which it is to be aligned.
A wireframe model was used for graphical rendering because it was observed to diminish the effect of incorrect graphical interposition cues and to provide a higher visibility of task space.

 Oh What a Tangled Web We Weave: Metaphor and Mapping in Graphical Interfaces
Graphical interfaces are typically thought to be effective because they use metaphors to everyday objects in order to suggest their functionality.
True graphical metaphors (such as the family tree in Figure 1) are used only rarely for perceptual mappings, and when they are they usually take the form of metonymy, in which parts are used to stand for wholes (e.g., when the letter "A" is used to stand for a text-writing tool in graphics programs).
Graphical expressions of novel structures (e.g., windows) may not be able to convey all the functionality being offered or to provide it with a unified identity.

This step requires additional work on the user's part and is, in fact, not even a practical solution in the case of a three-dimensional perspective graphical display, where changing the viewpoint causes large changes in the spatial relationship of the displayed graphical objects.
In an interactive computer graphics environment, the three main differences are that; (1) the labeled objects change position with time, (2) little time is available for computing the label positions (a fraction of a second), and, (3) a human user observes the labels as they move around the display.
An apparatus for positioning labels among graphical elements on a computer graphics display, comprising: means for identifying at least a first cluster of overlapping labels; means for calculating new display coordinates for at least one label in said cluster; and means for moving said label in accordance with said new display coordinates.

 Introduction
With a more realistic perspective display, the indication of ascending, descending, or steady flight is integrated directly and naturally into the aircraft representation while more precise information may still be obtained from text readouts.
Bemis, Leeds, and Winer (1988) which investigated the utility of a perspective naval tactical display, and one by Burnett and Barfield (1991) that analyzed the use of a perspective display for air traffic control.
Using either the plan-view or perspective display, the task was to identify any potentially hostile aircraft that appeared in the display and to assign an interceptor to each identified threat.

In short, topic maps can provide a graphical interface for building, validating and navigating a topic space which may be more intuitive than other information retrieval systems.
Though most of the theoretical background stems from a logical perspective, it would at least be interesting to investigate whether the topic map formalism can be extended and improved by introducting probabilities.

Pictorials show an image of an object as viewed from a skew direction in order to reveal all three directions (axes) of space in one picture.
Orthographic pictorial, rote, instrument drawings are often used to approximate Graphical Perspective projections, but there is attendant distortion in the approximation.
Because pictorial projections innately have this distortion, in the rote, instrument drawing of Pictorials, great liberties may then be taken for economy of effort and best effect.

 User Perspective
This is largely attributable to the computer’s origin as a mathematical machine, or “number cruncher”: it was assumed that people with the knowledge necessary to understand the mathematical problems the computers were solving were capable of working with cryptic interfaces.
In contrast, graphical user interfaces, have made it possible to use information technology without learning cryptic commands or even having a any understanding of how computers work.
In fact, the computer industry has introduced the term “end user” to refer to the typical computer user, because this person is at the end of the process of producing information technology, uninvolved in its design, and typically oblivious of how these technologies operate beyond and “beneath” the graphical user interface that is presented.
