Struct emath::Rot2[−][src]

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[src]

pub const IDENTITY: Self[src]

The identity rotation: nothing rotates

pub fn identity() -> Self[src]

👎 Deprecated:

Use Rot2::IDENTITY

pub fn from_angle(angle: f32) -> Self[src]

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

pub fn angle(self) -> f32[src]

pub fn length(self) -> f32[src]

The factor by which vectors will be scaled.

pub fn length_squared(self) -> f32[src]

pub fn is_finite(self) -> bool[src]

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

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