pillow-sphere

This is an experiment to generate rounded 3D shapes from 2D shapes by insetting their SDF according to the radius of a sphere. The goal is similar to pillow_medial, but the results do not look nearly as compelling. Also see pillow_sphere. The main difference from pillow_sphere is that we instead use the maximum of the SDF instead of 1, potentially preventing odd behavior for asymmetrical shapes.
