Matt Juntunen commented on GEOMETRY-154:
----------------------------------------
[~dimitrios.efthymiou], I'm not sold on the idea of adding this method based on
these use cases. For the graphics use case, there is already the
{{EuclideanVector.lerp}} method, which linearly interpolates between two
vectors. For the other use cases, one can compute the desired length ratios and
then use scalar multiplication to get the desired vectors. The computation of
the length ratios will depend on what the caller is trying to do and so should
not be part of this library, IMHO.
Ex:
{code:java}
// point between other points
Vector3D a = Vector3D.of(1, 2, 3);
Vector3D b = Vector3D.of(4, 5, 6);
Vector3D midPoint = a.lerp(b, 0.5);
// split the vector into two parts; in this case, we'll just do a simple 1/4,
3/4 split
Vector3D oneQuarter = a.multiply(0.25);
Vector3D threeQuarters = a.multiply(0.75);
{code}

> It takes a vector, say, u = (10) and divides it with ratio, say 1/2. That
> will return a pair of vectors v = (3.33) and w = (6.66). Regardless of
> dimensions, both vectors start at the point of origin
