Struct Rot2 

pub struct Rot2 { /* private fields */ }

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 const IDENTITY: Self

The identity rotation: nothing rotates

pub fn from_angle(angle: f32) -> Self

Angle is clockwise in radians. 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

pub fn inverse(self) -> Self

pub fn normalized(self) -> Self
