I tried again, with a bit more time, and: * I can compute shortest paths with the two algs * I cannot get meaningful convex hullsfor the two service area algs. I'm probably not understanting how the area algs work. Alex, could you please give a quick explanation, or point to an existing one, and/or share a sample project and params?
