Linear or point-projection perspective (from Latin perspicere 'to see through') is one of two types of graphical projection perspective in the graphic arts; the other is parallel projection. [ citation needed ] [ dubious – discuss ] Linear perspective is an approximate representation, generally on a flat surface, of an image as it is seen by ...
In 5-point perspective the vanishing points are mapped into a circle with 4 vanishing points at the cardinal headings N, W, S, E and one at the circle's origin. A reverse perspective is a drawing with vanishing points that are placed outside the painting with the illusion that they are "in front of" the painting.
This composition is a bijective map of the points of S 2 onto itself which preserves collinear points and is called a perspective collineation (central collineation in more modern terminology). [7] Let φ be a perspective collineation of S 2. Each point of the line of intersection of S 2 and T 2 will be fixed by φ and this line is called the ...
Two figures in a plane are perspective from a point O, called the center of perspectivity, if the lines joining corresponding points of the figures all meet at O. Dually , the figures are said to be perspective from a line if the points of intersection of corresponding lines all lie on one line.
A picture plane in perspective drawing is a type of projection plane. With perspective drawing, the lines of sight, or projection lines, between an object and a picture plane return to a vanishing point and are not parallel. With parallel projection the lines of sight from the object to the projection plane are parallel.
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. Perspective projection or perspective transformation is a projection where three-dimensional objects are projected on a picture plane. This has the effect that ...

Axonometry (cavalier perspective) of a house on checked pattern paper. In order to keep the drawing simple, one should choose simple foreshortenings, for example or . If two foreshortenings are equal, the projection is called dimetric.
