# na
na is a wrapper around [nalgebra](http://nalgebra.org/) 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:
```rust
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:
```rust
let m4: Mat4 = ...;
let v4: Vec4 = ...;
let v4_2 = m4.fast_mul(&v4);
```
- Fast versions of inversion for matrices
- GLSL style swizzles:
```rust
let xy = v3.xy()
let xz = v3.xz()
....
```
- Macros to easily create vectors:
```rust
let one = vec3!(1.); //sets all components to 1
let composed = vec3!(v2, z); // creates a Vector3 from a Vector2 and a float
...
```
- Easy to use traits for the most common types:
- BaseNum (Integers and reals)
- BaseInt
- BaseFloat
- NumVec (Vector of any number type)
- FloatVec
- NumPnt
- FloatPnt
