The central cylindrical projection is a perspective cylindrical map projection. It corresponds to projecting the Earth's surface onto a cylinder tangent to the equator as if from a light source at Earth's center. The cylinder is then cut along one of the projected meridians and unrolled into a flat map. [1]
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 ...
Cylindrical perspective is a form of distortion caused by fisheye and panoramic lenses which reproduce straight horizontal lines above and below the lens axis level as curved while reproducing straight horizontal lines on lens axis level as straight.
It is a perspective projection if the point of projection is allowed to vary with longitude: the point of projection being on the equator on the opposite side of the earth from the point being mapped and with the projective surface being a cylinder secant to the sphere at 45°N and 45°S. [2]
The point is then mapped to a plane by finding the point of intersection of that plane and the line. This produces an accurate representation of how a three-dimensional object appears to the eye. In the simplest situation, the center of projection is the origin and points are mapped to the plane z = 1 {\displaystyle z=1} , working for the ...

The term cabinet projection (sometimes cabinet perspective) stems from its use in illustrations by the furniture industry. [citation needed] Like cavalier perspective, one face of the projected object is parallel to the viewing plane, and the third axis is projected as going off in an angle (typically 30° or 45° or arctan(2) = 63.4°). Unlike ...
Another elongated grid is placed on the sidewalk based on a specific perspective, and visual elements of one are transcribed into the other, one grid square at a time. In 2016, the street artist JR completed a massive temporary anamorphic illusion over the Louvre 's pyramid, making the modern structure disappear and the original building appear ...
