  2. Barycentric coordinate system - Wikipedia

    en.wikipedia.org/wiki/Barycentric_coordinate_system

    Barycentric coordinates are strongly related to Cartesian coordinates and, more generally, affine coordinates.For a space of dimension n, these coordinate systems are defined relative to a point O, the origin, whose coordinates are zero, and n points , …,, whose coordinates are zero except that of index i that equals one.

  3. Barycenter (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Barycenter_(astronomy)

    In astronomy, barycentric coordinates are non-rotating coordinates with the origin at the barycenter of two or more bodies. The International Celestial Reference System (ICRS) is a barycentric coordinate system centered on the Solar System 's barycenter.

  4. Barycentric - Wikipedia

    en.wikipedia.org/wiki/Barycentric

    Barycentric subdivision, a way of dividing a simplicial complex; Barycentric coordinates (mathematics), coordinates defined by the vertices of a simplex; In numerical analysis, Barycentric interpolation formula, a way of interpolating a polynomial through a set of given data points using barycentric weights.

  5. Affine space - Wikipedia

    en.wikipedia.org/wiki/Affine_space

    The barycentric coordinates allows easy characterization of the elements of the triangle that do not involve angles or distances: The vertices are the points of barycentric coordinates (1, 0, 0), (0, 1, 0) and (0, 0, 1). The lines supporting the edges are the points that have a zero coordinate. The edges themselves are the points that have one ...

  6. Center of mass - Wikipedia

    en.wikipedia.org/wiki/Center_of_mass

    The coordinates R of the center of mass of a two-particle system, P 1 and P 2, with masses m 1 and m 2 is given by = + +. Let the percentage of the total mass divided between these two particles vary from 100% P 1 and 0% P 2 through 50% P 1 and 50% P 2 to 0% P 1 and 100% P 2 , then the center of mass R moves along the line from P 1 to P 2 .

  7. Barycentric and geocentric celestial reference systems

    en.wikipedia.org/wiki/Barycentric_and_geocentric...

    The barycentric celestial reference system (BCRS) is a coordinate system used in astrometry to specify the location and motions of astronomical objects. It was created in 2000 by the International Astronomical Union (IAU) to be the global standard reference system for objects located outside the gravitational vicinity of Earth: [1] planets, moons, and other Solar System bodies, stars and other ...

  8. Homogeneous coordinates - Wikipedia

    en.wikipedia.org/wiki/Homogeneous_coordinates

    Homogeneous coordinates are not uniquely determined by a point, so a function defined on the coordinates, say (,,), does not determine a function defined on points as with Cartesian coordinates. But a condition f ( x , y , z ) = 0 {\displaystyle f(x,y,z)=0} defined on the coordinates, as might be used to describe a curve, determines a condition ...

    The barycentric coordinates of N 2: ⁡ (): ⁡ (): ⁡ Two points closely related to the Napoleon points are the Fermat-Torricelli points (ETC's X(13) and X(14)). If instead of constructing lines joining the equilateral triangles' centroids to the respective vertices one now constructs lines joining the equilateral triangles' apices to the ...
