public static float SmoothStep (float from, float to, float t);


MinMax の間で制限したスムージングで補間します。

This function interpolates between min and max in a similar way to Lerp. However, the interpolation will gradually speed up from the start and slow down toward the end. This is useful for creating natural-looking animation, fading and other transitions.
