Computes the centroid or "center of gravity" of a triangle. The vectors can be 2D, 3D or n-dimensional.
var centroid = require('triangle-centroid') var tri = [ [10, 0, -4], [20, 2, 24], [30, 1, 4] ] centroid(tri) // -> [20, 1, 8]
centroid = triangleCentroid(triangle)
For the given
triangle, an array of 3 vectors, computes the centroid or "center of gravity".
Returns a new vector with the same dimension as the first point in
