Curvilinear barrel distortion Curvilinear pincushion distortion. Curvilinear perspective, also five-point perspective, is a graphical projection used to draw 3D objects on 2D surfaces, for which (straight) lines on the 3D object are projected to curves on the 2D surface that are typically not straight (hence the qualifier "curvilinear" [citation needed]).
Microsoft Visio (/ ˈ v ɪ z. i. oʊ /, VIZ-ee-oh), formerly Microsoft Office Visio, is a diagramming and vector graphics application and is part of the Microsoft 365 Business. The product was first introduced in 1992 by former American software company Visio Corporation , and its latest version is Visio 2021.
To complete the drawing to a straight-line combinatorially isomorphic re-embedding of G, v should be placed in the polygon and joined by straight lines to the vertices of the polygon. By the art gallery theorem , there exists a point interior to P at which v can be placed so that the edges from v to the vertices of P do not cross any other ...
Given parallel straight lines l and m in Euclidean space, the following properties are equivalent: Every point on line m is located at exactly the same (minimum) distance from line l (equidistant lines). Line m is in the same plane as line l but does not intersect l (recall that lines extend to infinity in either direction).
Except in the case of a line or circle, the parallel curves have a more complicated mathematical structure than the progenitor curve. [1] For example, even if the progenitor curve is smooth, its offsets may not be so; this property is illustrated in the top figure, using a sine curve as progenitor curve. [2]

However, parallel (non-crossing) pairs of lines are less restricted in hyperbolic line arrangements than in the Euclidean plane: in particular, the relation of being parallel is an equivalence relation for Euclidean lines but not for hyperbolic lines. [51] The intersection graph of the lines in a hyperbolic arrangement can be an arbitrary ...
