This can be used in mass points. http://mathworld.wolfram.com/BarycentricCoordinates.html This article is a stub. Help us out by expanding it.
Barycentric coordinates are triples of numbers 
corresponding to masses placed at the vertices of a reference triangle 
. These masses then determine a point 
, which is the geometric centroid of the three masses and is identified with coordinates . The vertices of the triangle are given by 
, 
, and 
. Barycentric coordinates were discovered by Möbius in 1827 (Coxeter 1969, p. 217; Fauvel et al. 1993).
