Half-Plane Intersection
Half-plane intersection (HPI) computes the common region that satisfies many linear side-of-line constraints in the plane.

Minkowski Sum
The Minkowski sum A ⊕ B adds every point of set A to every point of set B, and for convex polygons it can be computed in O(n + m) by merging edge directions.
