Struct emath::Rot2

pub struct Rot2 { /* fields omitted */ }

Represents a rotation in the 2D plane. A rotation of 𝞃/4 = 90° rotates the X axis to the Y axis. Normally a Rot2 is normalized (unit-length). If not, it will also scale vectors.

Implementations

impl Rot2

pub fn identity() -> Self

pub fn from_angle(angle: f32) -> Self

A 𝞃/4 = 90° rotation means rotating the X axis to the Y axis.

pub fn angle(self) -> f32

pub fn length(self) -> f32

The factor by which vectors will be scaled.

pub fn length_squared(self) -> f32

pub fn is_finite(self) -> bool

#[must_use]pub fn inverse(self) -> Rot2

#[must_use]pub fn normalized(self) -> Self
