Basically the formulation of the problem I'd like to solve is very simple. Given 2 simple polygons (without self-intersections) report all intersecting edge pairs in O(n+k) time, where n - is a total number of edges, k - number of intersections between two polygons. It is very important to stay within mentioned time hardness. What does surprise me, that I could hardly find information on this subject. Polygon intersections seems to be so natural and important problem. Anyway at the moment I don...
Answer:
The $\mathcal{O}(n+k)$ algorithms seem to be limited to convex polygons. The fastest algorithms that...
