I need a (simple), immutable, 2D vector library for Java or Scala

Question

I've been searching for a whole day. I've tried Simplex3D Scala library. But it's poorly documented and I don't even manage to get a vector normalized after downloading an older release because the current one doesn't run.

javax.vecmath is not immutable so it not nice to use in Scala.

commons-math is more into the scientific math direction with no convenience for 2D (or 3D) use.

Answer 1

I couldn't find one when I needed one. So I built one, and I've always been intending to release it. I'm too busy to do anything with it now, but I could probably make it available next week if a better answer is not forthcoming.

Answer 2

I've just done some more research. Slick2D seems to contain a Vector2f class that has immutable methods. Though that's not very much and can be done by hand in maybe an hour.
