parallel coordinates
1Parallel coordinates — is a common way of visualizing high dimensional geometry and analyzing multivariate data. To show a set of points in an n dimensional space, a backdrop is drawn consisting of n parallel lines, typically vertical and equally spaced. A point in n… …
2Parallel 36°30′ north — 36.5° 36.5th parallel north …
3Parallel (geometry) — Parallelism is a term in geometry and in everyday life that refers to a property in Euclidean space of two or more lines or planes, or a combination of these. The assumed existence and properties of parallel lines are the basis of Euclid s… …
449th parallel north — This article is about the circle of latitude in the northern hemisphere. For other uses, see 49th parallel (disambiguation). 49° 49th parallel north …
5Plücker coordinates — In geometry, Plücker coordinates, introduced by Julius Plücker in the 19th century, are a way to assign six homogenous coordinates to each line in projective 3 space, P 3. Because they satisfy a quadratic constraint, they establish a one to one… …
6Curvilinear coordinates — Curvilinear, affine, and Cartesian coordinates in two dimensional space Curvilinear coordinates are a coordinate system for Euclidean space in which the coordinate lines may be curved. These coordinates may be derived from a set of Cartesian… …
7Bipolar cylindrical coordinates — are a three dimensional orthogonal coordinate system that results from projecting the two dimensional bipolar coordinate system in theperpendicular z direction. The two lines of foci F {1} and F {2} of the projected Apollonian circles are… …
8Gullstrand-Painlevé coordinates — GullStrand Painlevé (GP) coordinates were proposed by Paul Painlevé [Paul Painlevé, “La mécanique classique et la théorie de la relativité”, C. R. Acad. Sci. (Paris) 173, 677–680 (1921). ] and Allvar Gullstrand [Allvar Gullstrand, “Allgemeine… …
9Bipolar coordinates — are a two dimensional orthogonal coordinate system. There are two commonly defined types of bipolar coordinates. [http://bbs.sachina.pku.edu.cn/Stat/Math World/math/b/b233.htm Eric W. Weisstein, Concise Encyclopedia of Mathematics CD ROM, Bipolar …
10Toroidal coordinates — are a three dimensional orthogonal coordinate system that results from rotating the two dimensional bipolar coordinate system about the axis that separates its two foci. Thus, the two foci F {1} and F {2} in bipolar coordinates become a ring of… …
