Struct InOutSmoother 

Source 
pub struct InOutSmoother;
Expand description

The InOutSmoother Curve (standard smootherstep).

Ken Perlin’s smootherstep: 6t⁵ - 15t⁴ + 10t³

Has zero first AND second derivatives at endpoints for extra smoothness. Starts slow, speeds up in the middle, slows down at the end.

§examples.
use eazy::Curve;
use eazy::interpolation::polynomial::smootherstep::InOutSmoother;

let p = InOutSmoother.y(0.5);
assert_eq!(p, 0.5);
