This paper proposes a new algorithm for querying the shortest path between two pointssandtin a simple polygonPbased on Voronoi diagram(VD). Based on the polygon’s VD, we first find the Voronoi skeleton pathS(s,t) from pointstot, and then along which we compute the shortest pathSP(s,t) by visibility computing simultaneously.SP(s,t) can be reported in timeO(n). It can be used in our 3D virtual museum system, in which the polygon’s VD is used as a data structure for path planning, visibility computing, collision detection, and so on.
