Implementations

impl Quaternion

fn from_direction_and_angle(vector: &DirectionVector, angle: f64) -> Self

Return a quaternion from a unit direction vector and angle (unit: radian).

fn dot(&self, other: &Self) -> f64

Calculate the dot product.

fn scale(&self, factor: f64) -> Self

Return the scaled quaternion by a factor.

Trait Implementations
