Creating round corner base on curves other than radius of a circle, like exponential curves?

[kaihin30]

So I have the question poped up when I saw the new xiaomi logo.

(Lets not talk about if its looking nice here :v)

If I would like to create round corner base on exponential math curves instead of circle radius,

how could I achieve this in Ai?

Unless you create a script that calculates the exact mathematical values and sets the positions and tangents of the anchor points accordingly, simply eyeball it. Each corner should not take more than three points and of course it would be useful to e.g. get Astute's mirroring plug-in to keep things symmetrical if you don't want to work with complex guides and numerical transforms...
