Function: smoothstep()
function smoothstep(min: number, max: number, x: number): number
The function interpolates smoothly between two input values based on a third one that should be between the first two. The returned value is clamped between 0 and 1.
The slope (i.e. derivative) of the smoothstep function starts at 0 and ends at 0. This makes it easy to create a sequence of transitions using smoothstep to interpolate each segment rather than using a more sophisticated or expensive interpolation technique.
See https://en.wikipedia.org/wiki/Smoothstep for more details.
Parameters
min
number
The lower bound of the interpolation range.
max

The value to interpolate.
Returns
number
The smoothly interpolated value clamped between zero and one.
