The value of parallel coordinates is that certain geometrical properties in high dimensions transform into easily seen 2D patterns. For example, a set of points on a line in n-space transforms to a set of polylines in parallel coordinates all intersecting at n − 1 points.
The distance between two parallel lines in the plane is the minimum distance between any two points. ... to get the coordinates of the intersection points. The ...
The coordinate y is related to the coordinate x through the relation y 1 = r cos x / r and y 2 = r sin x / r . This gives ∂y 1 / ∂x = −sin x / r and ∂y 2 / ∂x = cos x / r In this case the metric is a scalar and is given by g = cos 2 x / r + sin 2 x / r = 1. The interval is ...
Rational Bézier curve – polynomial curve defined in homogeneous coordinates (blue) and its projection on plane – rational curve (red) In mathematics, homogeneous coordinates or projective coordinates, introduced by August Ferdinand Möbius in his 1827 work Der barycentrische Calcul, [1] [2] [3] are a system of coordinates used in projective geometry, just as Cartesian coordinates are used ...
2.1 Coordinate systems. 2.2 Embedding in three-dimensional space. 2.3 Polytopes. ... It is an affine space, which includes in particular the concept of parallel lines.
In geometry, a point is an abstract idealization of an exact position, without size, in physical space, [1] or its generalization to other kinds of mathematical spaces.As zero-dimensional objects, points are usually taken to be the fundamental indivisible elements comprising the space, of which one-dimensional curves, two-dimensional surfaces, and higher-dimensional objects consist; conversely ...
Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.

Let the forces on the system be F j (j = 1, 2, …, m) be applied to points with Cartesian coordinates r j (j = 1, 2, …, m), then the virtual work generated by a virtual displacement from the equilibrium position is given by = =.
