View source for Descriptive geometry

'''Descriptive geometry''' is the branch of [[geometry]] which allows the representation of three-dimensional objects in two dimensions, by using a specific set of procedures (see also [[Algorithm]]).

The resulting techniques are important for [[engineering]], [[architecture]], [[design]] and in [[art]].

The theoretical basis for descriptive geometry is provided by [[Planar geometric projection|planar geometric projections]]. [[Gaspard Monge]] is usually considered the "father of descriptive geometry". He first developed his techniques to solve geometric problems in 1765 while working as a draftsman for military fortifications, and later published his findings.

Monge's protocols allow an imaginary object to be drawn in such a way that it may be 3-D modeled. All geometric aspects of the imaginary object are accounted for in true size/to-scale and shape, and can be imaged as seen from any position in space. All images are represented on a two-dimensional surface.

Descriptive geometry uses the image-creating technique of imaginary, parallel projectors emanating from an imaginary object and intersecting an imaginary plane of projection at right angles. The cumulative points of intersections create the desired image.
