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 Algorithm).

Description
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.
The resulting techniques are important for engineering, architecture, design and in art.
The theoretical basis for descriptive geometry is provided by planar geometric projections.
History
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.
