Function quat::nlerp

pub fn nlerp<'out, T, F>(
    out: &'out mut [T; 4], 
    a: &[T; 4], 
    b: &[T; 4], 
    t: &F
) -> &'out mut [T; 4] where
    T: Real + Cast<F>,
    F: Clone + Cast<T>,
    T: AddAssign<&'a T>,
    F: MulAssign<&'a F>,
    &'a T: Sub<&'b T, Output = T> + Mul<&'b T, Output = T> + Div<&'b T, Output = T>, 

Example

use std::f32::consts::FRAC_2_PI;
let mut q = quat::new_one::<f32>();

let a = quat::new_identity();
let mut b = quat::new_identity();
quat::rotate_z_mut(&mut b, &FRAC_2_PI);

quat::nlerp(&mut q, &a, &b, &0.5_f32);
assert_eq!(q, [0.4829259, 0.4829259, 0.55849457, 0.47079617]);
