Feature suggestion: interpolating off-curve points in polar coordinates

Hello :slight_smile: Please forgive my poor English.

I am not sure if this really works, but how about adding a way to interpolate off-curve points in polar coordinates? The procedure is as follows:

  1. First convert the x-y coordinates of an off-curve point into angle-radius coordinates with the on-curve point being a pole,
  2. Then interpolate them (always abs(Δangle) < 180°),
  3. Then convert them back to x-y.

At least this will avoid creating kinks, I think.

I am sorry if this can not work as I expect it to, or if this topic has already been brought up and deemed to be of no use (I searched and found none).

That sounds interesting. I’ll try this.
