Struct siege_math::matrix::Mat2
[−]
[src]
#[repr(C)]pub struct Mat2<F> { pub x: Vec2<F>, pub y: Vec2<F>, }
A 2x2 matrix.
This matrix is internally stored column-major (as that is better for GPU compatibility and possibly other reasons), but the API (e.g. the order of function parameters to the new() function) is row-major, since that is how people write matrices on paper.
Fields
x: Vec2<F>
y: Vec2<F>

impl<F: FullFloat> ApproxEq for Mat2<F>
[src]
type Flt = F
fn approx_eq(
&self,
