Struct cogl::Euler

pub struct Euler(_);

Implementations

impl Euler

pub fn init(&mut self, heading: f32, pitch: f32, roll: f32)

Initializes self to represent a rotation of x_angle degrees around the x axis, then y_angle degrees around the y_axis and z_angle degrees around the z axis.

heading

Angle to rotate around an object’s y axis

pitch

Angle to rotate around an object’s x axis

roll

Angle to rotate around an object’s z axis

pub fn init_from_matrix(&mut self, matrix: &Matrix)

Extracts a euler rotation from the given matrix and initializses self with the component x, y and z rotation angles.

matrix

A Matrix containing a rotation, but no scaling, mirroring or skewing.

Trait Implementations
