na

na is a wrapper around nalgebra to make it easier and mostly less verbose to work with the most used types in vector math for graphics.

na shortens the most common types Vector*, Point*, Quaternion... to Vec*, Pnt*, Quat... and defaults the generic parameters to f32 so you can write:

struct Pos(Vec3);

It also inlcudes some other functionalities not yet present in nalgebra:

Fast versions of multiplication of matrices (including matrices with vectors) that can be used by calling:

let m4: Mat4 = ...;
let v4: Vec4 = ...;
let v4_2 = m4.fast_mul(&v4);

let xy = v3.xy()
let xz = v3.xz()
....

let one = vec3!(1.); //sets all components to 1
let composed = vec3!(v2, z); // creates a Vector3 from a Vector2 and a float
...
