Planar Minkowski Sums
Reference Manual

Introduction

This package consist of functions for computing the Minkowksi sum of two polygons in the plane. Namely, given two polygons $$P,Q ² it computes $$P Q = { p + q  |  p P, q Q }.

In addition, the package also includes functions for offsetting a polygon, namely computing its Minkowski sum with a disc of a given radius, and for insetting a polygon (namely computing its inner offset). It is possible to compute the exact representation of the offset (or the inset), or to approximate it with guaranteed error bounds, in order to speed up the computation time.
