barycentric coordinate system

Utilizing a barycentric coordinate system, the resulting probability vector is represented as a point in an equilateral triangle (Fig.

The element provides an approximation for the exact solution of a partial differential equation which is parametrized Barycentric coordinate system (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 (a triangle, tetrahedron, etc.).
