Toxiclibs- get boundary edges only

julia789

Hello,

I am trying to get just the boundary edges of a WETriangleMesh Plane, so the edges and vertices which make up the 2d boundingbox of a plane.

From the AABB of the boundingbox, I could get the min and max, but what I am trying to do is to check if the edge is a boundary edge of the mesh, so any edge which has 3 connections and not four, if that makes sense.

Any way to do this?
