Function smoothstep_between 

Source 
pub fn smoothstep_between<T: Real>(edge0: T, edge1: T, x: T) -> T
Expand description

Parameterized smoothstep: C1 interpolation between edge0 and edge1.

Returns 0 when x <= edge0, 1 when x >= edge1, and a smooth Hermite interpolation between them otherwise. Formula: t = clamp((x - edge0) / (edge1 - edge0), 0, 1), result: t^2 * (3 - 2t).
