In Java palance, the 'void' return means the result comes back in 'this'
(the object on which the method was called).

So would I, give or take a few parentheses:
Point3f resultPoint = new
Point3f(firstPoint3f.sub(secondPoint3f).scale(3.5));
This looks ok to me. Never mind that Point3f - Point3f should be Vector3f,
but that belongs in my other rant.

You're fighting a lost battle in the lost war on operator overloading in
Java. It just ain't gonna happen. If we can't get overloading for Complex,
we ain't gonna get it for anything else. Deal with it. :-)
