What (who) is 3D projection - definition


3D projection         
  • axonometric views]]
  • Axonometric projection of a scheme displaying the relevant elements of a vertical [[picture plane]] perspective. The standing point (P.S.) is located on the ground plane ''π'', and the point of view (P.V.) is right above it. P.P. is its projection on the picture plane ''α''. L.O. and L.T. are the horizon and the ground lines (''linea d'orizzonte'' and ''linea di terra''). The bold lines '''s''' and '''q''' lie on ''π'', and intercept ''α'' at ''Ts'' and ''Tq'' respectively. The parallel lines through P.V. (in red) intercept L.O. in the vanishing points ''Fs'' and ''Fq'': thus one can draw the projections '''s′''' and '''q′''', and hence also their intersection '''R′''' on '''R'''.
  • Parallel projection corresponds to a perspective projection with a hypothetical viewpoint; i.e. one where the camera lies an infinite distance away from the object and has an infinite focal length, or "zoom".
  • Symbols used to define whether a multiview projection is either First Angle (left) or Third Angle (right).
  • Perspective of a geometric solid using two vanishing points. In this case, the map of the solid (orthogonal projection) is drawn below the perspective, as if bending the ground plane.

METHODS IN COMPUTER GRAPHICS TO PROJECT THREE-DIMENSIONAL OBJECTS ONTO A PLANE BY MEANS OF NUMERICAL CALCULATIONS
Perspective transform; Graphical projection; Graphical Projection; Mapping 3D to 2D; 3d projection; Camera transform; Weak perspective; Projection matrix (computer graphics); Perspective transformation; 3-D projection
A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.

  • An [[Albers projection]] shows areas accurately, but distorts shapes.
  • An azimuthal equidistant projection shows distances and directions accurately from the center point, but distorts shapes and sizes elsewhere.
  • The [[Gnomonic projection]] is thought to be the oldest map projection, developed by [[Thales]] in the 6th century BC
  • The Mercator projection shows [[rhumbs]] as straight lines. A rhumb is a course of constant bearing. Bearing is the compass direction of movement.

  • A [[stereographic projection]] is conformal and perspective but not equal area or equidistant.
  • This [[transverse Mercator projection]] is mathematically the same as a standard Mercator, but oriented around a different axis.

PSYCHOLOGICAL PROJECTION; Projection (psychology); Freudian projection; Projection (Psychology); Projection psychology; Psychologically projecting; Shame dumping; Deflection (psychology)
Psychological projection is the process of misinterpreting what is "inside" as coming from "outside". It forms the basis of empathy by the projection of personal experiences to understand someone else's subjective world.
