Abstract: In this report, we present an O(n^2) algorithm for finding the exact shortest paths from a fixed source point to all other points on a triangulated convex polyhedral surface in three-dimensional space using the concept of funnels.  Because of special shape of the funnels, the algorithm does not use planar unfolding technique that almost known exact algorithms rely on.
