Is there a function or script that allows you to soften a geometry (a kind of inscribed smoothing that follows the contour of the geometry)

at the moment, I don't have much of an idea (a priori a buffer doesn't work, the minimum oriented footprints are rectangular, the convex envelopes are too big)...

    Is this about symbology, or the actual geometry?

Use the native:smoothgeometry algorithm in QGIS.


Have you tried the QGIS simplify tool?

I finish with WhiteBox Tools / smoothVectors enter image description here
