Tuples

Tuples are set of 2 to 4 values of either float or double. They are implemented by the classes: PointXY, VectorXY, where X is the dimension (2 to 4) and Y is the type (d, or f).

Math operator

Tuple + Tuple
Tuple += Tuple
Tuple * Number
Number * Tuple
Tuple *= Number
- Tuple
Tuple / Number
Tuple - Tuple
Tuple -= Tuple

This operators work for tuples of the same dimension. E.g. Point2f and Vector2f or Point2d and Point2f.

Vector3f a = new Vector3f(0,1,2);
Vector3f b = new Vector3f(0,2,3);
 
println(a + b); //(0.0, 3.0, 5.0)
println(a + a + b); //(0.0, 4.0, 7.0)
println(a - b); //(0.0, -1.0, -1.0)
println(a - a - b); //(0.0, -2.0, -3.0)
println(a * 3); //(0.0, 3.0, 6.0)
println(a /2); //(0.0, 0.5, 1.0)
println(a /1.3); //(0.0, 0.7692308, 1.5384616)
