Struct emath::Rot2 [−][src]
Represents a rotation in the 2D plane.
A rotation of π/4 = 90Β° 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]

π Deprecated:
Use Rot2::IDENTITY
pub fn from_angle(angle: f32) -> Self
[src]
A π/4 = 90Β° 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
