      @danielchooper You could get arbitrarily close with piecewise Beziers or a ~5th order polynomial. Where are you trying to use them?

      @danielchooper They appear to show the timing curves in the video; easy to trace. Crude PoC here: https://github.com/warrenm/swift-easing-functions …

      @danielchooper No sweat; I’ve always wanted to use that API. Let me know if you find a closer approximation or better technique.
