Struct comfy_wgpu::epaint::emath::Rot2

#[repr(C)]
pub struct Rot2 { /* private fields */ }
Expand description

Represents a rotation in the 2D plane. A rotation of ๐žƒ/4 = 90ยฐ rotates the X axis to the Y axis. Normally a Rot2 is normalized (unit-length). If not, it will also scale vectors.

Implementationsยง

ยง

impl Rot2

pub const IDENTITY: Rot2 = _

The identity rotation: nothing rotates

pub fn from_angle(angle: f32) -> Rot2

Angle is clockwise in radians. A ๐žƒ/4 = 90ยฐ 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) -> Rot2

pub fn normalized(self) -> Rot2
