code: public static boolean equal(Vector3f v1, Vector3f v2) {
          return equal(v1.x, v2.x) && equal(v1.y, v2.y) && equal(v1.z, v2.z);
      }
docs: Are these two numbers effectively equal?
  
  The same logic is applied for each of the 3 vector dimensions: see  {@link #equal}
  @param v1
  @param v2
