    Quaternion::new(0.5, 0.0, 0.0, 0.5),
    Quaternion::new(0.5, 0.0, 0.5, 0.0)
));

    DualQuaternion::from_real_and_dual(
        Quaternion::new(0.5, 0.0, 0.4, 0.1),
        Quaternion::new(0.1, 0.4, 0.1, 0.4)
    )
), epsilon = 1.0e-6);

pub fn sclerp(&self, other: &Self, t: T) -> Selfwhere
    T: RealField,

Screw linear interpolation between two unit quaternions. This creates a smooth arc from one dual-quaternion to another.

Panics if the angle between both quaternion is 180 degrees (in which case the interpolation is not well-defined). Use .try_sclerp instead to avoid the panic.

Example

let dq1 = UnitDualQuaternion::from_parts(
    Vector3::new(0.0, 3.0, 0.0).into(),
    UnitQuaternion::from_euler_angles(std::f32::consts::FRAC_PI_4, 0.0, 0.0),
);

let dq2 = UnitDualQuaternion::from_parts(
    Vector3::new(0.0, 0.0, 3.0).into(),
    UnitQuaternion::from_euler_angles(-std::f32::consts::PI, 0.0, 0.0),
);

let dq = dq1.sclerp(&dq2, 1.0 / 3.0);

assert_relative_eq!(
    dq.rotation().euler_angles().0, std::f32::consts::FRAC_PI_2, epsilon = 1.0e-6
);
assert_relative_eq!(dq.translation().vector.y, 3.0, epsilon = 1.0e-6);

pub fn try_sclerp(&self, other: &Self, t: T, epsilon: T) -> Option<Self>where
    T: RealField,

Computes the screw-linear interpolation between two unit quaternions or returns None if both quaternions are approximately 180 degrees apart (in which case the interpolation is not well-defined).

Arguments
