Barycentric coordinates
Encyclopedia
Barycentric can refer to:

In astronomy,
  • Barycentric coordinates (astronomy)
    Barycentric coordinates (astronomy)
    In astronomy, barycentric coordinates are non-rotating coordinates with origin at the center of mass of two or more bodies.The barycenter is the point between two objects where they balance each other. For example, it is the center of mass where two or more celestial bodies orbit each other...

    , coordinates defined by the common center of mass of two or more bodies
  • Barycentric Dynamical Time
    Barycentric Dynamical Time
    Barycentric Dynamical Time is a relativistic coordinate time scale, intended for astronomical use as a time standard to take account of time dilation when calculating orbits and astronomical ephemerides of planets, asteroids, comets and interplanetary spacecraft in the Solar system...

    , a former time standard in the Solar system
  • Barycentric Coordinate Time
    Barycentric Coordinate Time
    Barycentric Coordinate Time is a coordinate time standard intended to be used as the independent variable of time for all calculations pertaining to orbits of planets, asteroids, comets, and interplanetary spacecraft in the Solar system...

    , a coordinate time standard in the Solar system
  • barycentre, the point between two objects where they balance each other


In geometry,
  • barycentric subdivision
    Barycentric subdivision
    In geometry, the barycentric subdivision is a standard way of dividing an arbitrary convex polygon into triangles, a convex polyhedron into tetrahedra, or, in general, a convex polytope into simplices with the same dimension, by connecting the barycenters of their faces in a specific way.The name...

    , a way of dividing a simplicial complex
    Simplicial complex
    In mathematics, a simplicial complex is a topological space of a certain kind, constructed by "gluing together" points, line segments, triangles, and their n-dimensional counterparts...

  • Barycentric coordinates (mathematics)
    Barycentric coordinates (mathematics)
    In geometry, the barycentric coordinate system is a coordinate system in which the location of a point is specified as the center of mass, or barycenter, of masses placed at the vertices of a simplex . Barycentric coordinates are a form of homogeneous coordinates...

    , coordinates defined by the vertices of a simplex
    Simplex
    In geometry, a simplex is a generalization of the notion of a triangle or tetrahedron to arbitrary dimension. Specifically, an n-simplex is an n-dimensional polytope which is the convex hull of its n + 1 vertices. For example, a 2-simplex is a triangle, a 3-simplex is a tetrahedron,...
