history of perspective drawing by Patricia Moore on Prezi
This peephole or "peep show" tracing method does not make clear that linear perspective is really created by straight lines passing through a vertical plane. For that, the perspective "machine" (diagram, above) by the German artist Albrecht Dürer (1471-1528) is a better example. By looping a weighted string through an eye ring in the wall, one artist could hold the opposite end along the contours of a lute; a second artist could measure the height and horizontal position of the string where it passed through a rectangular frame, then transfer this point to a paper or canvas (shown as a hinged panel). By repeating the measurements dozens or hundreds of times, a "connect the dots" perspective view of the three dimensional lute could be constructed on a two dimensional surface. Through similar empirical methods, Renaissance artists worked out the geometric fundamentals of perspective technique.
Transcript of history of perspective drawing
. Everything in perspective arises from four perspective facts the straight line path of light, a fixed viewpoint, the visual cone centered on the direction of view, and the image cross section through the visual cone.
The graticulate frame was used to assist in the creation of correct perspective, while mirrors with reducing convex mirrors or concave lenses were also used (especially in the 17th and 18th centuries) as drawing aids as was the camera obscura.

To him, the presence of identical fossil species alongthe coastal parts of Africa and South America was the most compelling evidencethat the two continents were once joined.
In Wegener's mind, the drifting of continents after the break-up of Pangaeaexplained not only the matching fossil occurrences but also the evidenceof dramatic climate changes on some continents.
The principles of perspective drawing were elucidated by …
(2) Greater realism and consequent attention to detail, as reflected in the development of linear perspective and the increasing realism of human faces and bodies; this new approach helps to explain why classical sculpture was so revered, and why Byzantine art fell out of fashion.

. The step by step method for constructing a three dimensional rectangular solid using 1PP or central perspective projection methods, with emphasis on the artistic decisions that are part of the process.

Despite the numerical superiority of the Arab armies, Israel defended itself each time and won. After each war Israeli army withdrew from most of the areas it captured (). This is unprecedented in World history and shows Israel's willingness to reach peace even at the risk of fighting for its very existence each time anew.
Perspective (graphical) - Wikipedia
What we have just created through the division of a given space, is the grid. We have made a vertical grid, but we can also make a horizontal grid for ceilings and floors. The grid is fundamental in creating an accurate representation of three-dimensional space and for the accurate placement of figures in that created space. Consider the overlapping of objects that were studied in lesson 2. There it was pointed out that the two figures standing alongside Otto III were occupying the same space. You can see this by examining the placement of their feet. A true perspective space was not created for the rear figure to stand in, so his feet are awkwardly entangled with those of the front figure. If the artist had been able to project a grid into his painting, much like a chessboard, then the rear figure could be accurately placed on a different tile than the front figure.
