Tóm tắt: In this report, we present Chen and Han's algorithm introduced in 1990 for determining the shortest path between two arbitrary points on the surface of a convex polyhedron or a non-convex polyhedron. The algorithm uses a "Continuous Dijkstra" technique based on the key observation “one angle one split” with O(n2) complexity. In addition, Kavena and O'Rourke's implementation in 2000 is presented (cont.).
