Anotations

Scope note:

Refers to a technique for representing three-dimensional objects in two dimensions by using parallel projecting lines that are perpendicular to the plane of projection or picture surface. Principal surfaces of objects are parallel to the picture plane. It does not include foreshortening, shifts in scale and proportion, or other distortions that would be caused by employing linear perspective. It is often used for technical and architectural drawings, including plans, sections, and elevations. It is also used to create azimuthal projections of the Earth or another heavenly body as seen from space.
