- padded boundary of convex hull 4 answers
I would like to represent the ɛ-neighborhood of a convex polygon, which is the Minkowski sum of the polygon and a disk of radius ɛ. The polygon is given by its vertices, from which of course I could calculate a drawing, but I hope that there is a simpler solution using TikZ (though I'm equally happy with any other solution). Here is an example, the ɛ-neighborhood of a triangle.
