Orthographic projection in the context of "Architectural plan"

In technical drawing and computer graphics, a multiview projection is a technique of illustration by which a standardized series of orthographic two-dimensional pictures are constructed to represent the form of a three-dimensional object. Up to six pictures of an object are produced (called primary views), with each projection plane parallel to one of the coordinate axes of the object. The views are positioned relative to each other according to either of two schemes: first-angle or third-angle projection. In each, the appearances of views may be thought of as being projected onto planes that form a six-sided box around the object. Although six different sides can be drawn, usually three views of a drawing give enough information to make a three-dimensional object.

These three views are known as front view (also elevation view), top view or plan view and end view (also profile view or section view).

In architecture and building engineering, a floor plan is a technical or diagrammatic drawing that illustrates the horizontal relationships of interior spaces or features to one another at one level of a structure. They are typically drawn to-scale and in orthographic projection to represent relationships without distortion. They are usually drawn approximately 4 ft (1.2 m) above the finished floor and indicate the direction of north.

The level of detail included on a floor plan is directly tied to its intended use and phase of design. For instance, a plan produced in the schematic design phase may show only major divisions of space and approximate square footages while one produced for construction may indicate the construction types of various walls. Floor plans may indicate specific dimensions or square footages for particular rooms and/or walls. They may also include details of fixtures (sinks, water heaters, furnaces, etc), notes to specify finishes, construction methods, or symbols for electrical items. They may be rendered or drafted.

In three-dimensional geometry, a parallel projection (or axonometric projection) is a projection of an object in three-dimensional space onto a fixed plane, known as the projection plane or image plane, where the rays, known as lines of sight or projection lines, are parallel to each other. It is a basic tool in descriptive geometry. The projection is called orthographic if the rays are perpendicular (orthogonal) to the image plane, and oblique or skew if they are not.

Pan-Asianism (also known as Asianism or Greater Asianism) is an ideology aimed at creating a political and economic unity among Asian peoples. Various theories and movements of Pan-Asianism have been proposed, particularly from East, South and Southeast Asia. The motive for the movement was in opposition to the values of Western imperialism and colonialism, and that Asian values were superior to European values.

The concept of Asianism in Japan and China has changed during the early 20th century from a foreign-imposed and negatively received, to a self-referential and embraced concept, according to historian Torsten Weber.

Orthographic projection in cartography has been used since antiquity. Like the stereographic projection and gnomonic projection, orthographic projection is a perspective projection in which the sphere is projected onto a tangent plane or secant plane. The point of perspective for the orthographic projection is at infinite distance. It depicts a hemisphere of the globe as it appears from outer space, where the horizon is a great circle. The shapes and areas are distorted, particularly near the edges.
