Returns the smooth step function result. The return value is 0.0 if x <= edge0, 1.0 if x >= edge1, and performs smooth Hermite interpolation between 0.0 and 1.0 when edge0 < x < edge1.
The lower edge of the Hermite function.
The upper edge of the Hermite function.
The source value for interpolation.
Optional
Optional target options.
The smoothly interpolated value.
Returns the smooth step function result. The return value is 0.0 if x <= edge0, 1.0 if x >= edge1, and performs smooth Hermite interpolation between 0.0 and 1.0 when edge0 < x < edge1.
