Subject: Obtaining edge list from Delaunay triangulation From: Peter Bone Date: 13 Dec, 2010 12:16:05 Message: 1 of 7 
I'd like to get a list of unique edges from a Delaunay triangulation on a set of 2D points. The delaunay function returns the vertices of the triangles. If I extract the edges from this then most edges will be counted twice when performed for all triangles. My aim is to find the average distance of edges. I'm hoping for a simple method that doesn't require checking all previously found edges for each edge. Thanks.
