text: More generally, if an arbitrary origin is chosen where the Cartesian coordinates of the vertices are known and represented by the vectors A , B and C and if the point P has trilinear coordinates x : y : z, then the Cartesian coordinates of P are the weighted average of the Cartesian coordinates of these vertices using the barycentric coordinates ax, by and cz as the weights.
