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:

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
