1D, 2D, 3D and 4D vectors

Vectorz has special support for 1D, 2D, 3D and 4D vectors. These have the following properties:

• The elements are stored in public fields (x,y,z and t)
• They have specialised, efficient functions that operate on and return vectors of the same size / type
• They require less memory than regular Vector values of the same size, improving efficiency
• They still extend AVector, so you get all the standard Vectorz functionality as usual

These small fixed-size vectors are very useful in many circumstances, e.g.

• 2D and 3D graphics
• Representing RGB and ARGB colours (as 3D and 4D vectors)
• Physical modelling
• Complex numbers (as 2D vectors)
• Quaternions (as 4D vectors)

Examples

// create a new 3D vector
Vector3 v=Vector3.of(1,2,3);

// directly access the x-coordinate of a 3D vector
double x = v.x;

// add to a 3D vector (uses optimised 3D addition)
v.add(Vector3.of(2,3,4));
