Squircle & Astroid

This node allows to draw up to 3 different transitions from a square, rounding the corners or bending the sides in different ways.

You can morph from a square to a circle in two different ways, using “Lp Spaces” functions:

1. Rounding the corners in very organic way (like the so called “squircle”), a much natural and continuous curvature than using circle arcs.
2. Bending the sides to convey finally a circle.

And you can also morph from a square to an “astroid”, a particular type of roulette curve.

Interesting variations can be obtained using the Ratio & Switch Ratio controls, and also enabling gradient outputs, instead of pure black & white shapes.
