C# routing application for calculating a set of shortest paths from a series of predefined start and end locations. Each start node can be assigned an integer load value which accumulates on its corresponding end node. In order to compile this code, download and reference NetTopologySuite, an open source spatial analysis library, and QuickGraph,…

Pseudo-code for a medial axis transform algorithm based on Voronoi diagram.
//Get point cloud S from polygon P
//by running a densify operation
var S = P.Densify ();
//Create Voronoi diagram V for
//point cloud S
var V = Voronoi (S);
//Get intersection C of Voronoi diagram V
