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:
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);
Fast versions of inversion for matrices
GLSL style swizzles:
let xy = v3.xy() let xz = v3.xz() ....
- Macros to easily create vectors:
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)
- NumVec (Vector of any number type)
