I developed a Jetpack Compose smooth corners (G² continuity) library. The corner smoothing is superior to that in androidx.graphics.shapes.

You can control the smoothness in two ways: one is the proportion of the circular section, and the other is the distance from which the corner smoothing starts.

Awesome work! More libraries are always great to see.
AndroidX already has a graphics‑shapes library (by Chet Haase) — it includes a wide variety of shapes and smoothing/rounding corner functions (so you can do things like squircles, thanks to the smoothing capabilities). 🙂

Maybe your library uses different smoothing formulas.

Yes, but I investigated the smoothness of androidx, it is not actually G² continuous. I don't know why. If do G² for arbitrary Bezier curves we need to solve a quartic function, but it is a special quartic function which can be solved easier.
