Projection

Projection can be any of:

The display of an image by devices such as:

Map projection, reduces our three-dimensional planet to a flat map (Geography)
Graphical projection, the production of a two-dimensional image of a higher-dimensional object
- Orthographic projection, including:
  - Plan, or floor plan view
  - Elevation, usually a 'head-on' view of an exterior
  - Section, a cutaway view of the interior
  - Axonometric projection, including:
- Oblique projection, and
- Perspective projection

In chemistry, any one of:

Projection (mathematics), any of several different types of functions, mappings, operations, or transformations
- 3D projection
- Projection (relational algebra)
- Projection (linear algebra)
- Vector projection

This article is concerned with technical aspects of moving film projection A video projector takes a Video signal and projects the corresponding image on a Projection screen using a lens system An overhead projector (OHP is a variant of Slide projector that is used to display images to an audience A slide projector is an opto-mechanical device to view photographic slides. A map projection is any method of representing the Surface of a sphere or other shape on a plane. Graphical projection is a Protocol by which an image of an imaginary three-dimensional object is projected onto a planar surface without the aid of mathematical calculation Orthographic projection is a means of representing a three- Dimensional (3D object in two dimensions (2D A plan is an Orthographic projection of a 3-dimensional object from the position of a horizontal plane through the object A floor plan ( floorplan) in Architecture and Building engineering is a Diagram, usually to scale, of the relationships between rooms An elevation is an Orthographic projection of a 3-dimensional object from the position of a horizontal plane beside an object In Geometry, a cross section is the intersection of a body in 2-dimensional space with a line or of a body in 3-dimensional space with a plane etc Axonometric projection ("to measure along axes" is a technique used in orthographic pictorials Isometric projection is a form of Graphical projection —more specifically an Axonometric projection. Dimetric projection is a form of Axonometric projection, in which its direction of viewing is such that two of the three axes of space appear equally foreshortened of which Trimetric projection is a form of Axonometric projection, where the direction of viewing is such that all of the three axes of space appear unequally foreshortened This article discusses imaging of three-dimensional objects For an abstract mathematical discussion see Projection (linear algebra. Perspective (from Latin perspicere to see through in the graphic arts such as drawing is an approximate representation on a flat surface (such as paper of an image as it is perceived The Fischer projection, devised by Hermann Emil Fischer in 1891 is a Two-dimensional representation of a A Haworth projection is a common way of representing the cyclic structure of Monosaccharides with a simple three-dimensional perspective See also Conformational isomerism In Mathematics, a projection is any one of several different types of functions mappings operations or transformations for example the following In 3D projection is any method of mapping three-dimensional points to a two-dimensional plane Introduction In Relational algebra, a projection is a Unary operation written as \pi_{a_1. The vector resolute (also known as the vector projection) of two vectors \mathbf{a} in the direction of \mathbf{b} (also "\mathbf{a} Projective geometry is a non-Euclidean geometry that involves projective spaces. Projective geometry is a non- metrical form of Geometry, notable for its principle of duality. In another direction, projective modules and projective objects generalize free modules
Projections (Voyager episode), an episode of the television series Star Trek: Voyager
Power projection, the capacity of a state to implement policy by means of force, or the threat thereof, in an area distant from its own territory
Psychological projection, or "Freudian projection", a defense mechanism in which one attributes to others, one’s own unacceptable or unwanted thoughts or emotions
a forecasting of future developments based on current statistics and trends

In Mathematics, particularly in Abstract algebra and Homological algebra, the concept of projective module over a ring R is a more flexible generalisation In Category theory, the notion of a projective object generalizes the notion of Free module. " Projections " is the 19th episode of Star Trek Voyager, the third episode in the second season In Psychology, psychological projection (or projection bias) is a Defense mechanism in which one attributes one’s own unacceptable or unwanted thoughts Forecasting is the process of Estimation in unknown situations

a forecast or prognosis obtained by extrapolation
(psychology) an assumption that others have similar thoughts as oneself
(photography) the image that a translucent object casts onto another object
(geometry) something like a shadow, that an object casts onto another object.
(mathematics) transformations of one thing into something else, e.g. applications of functions.
