Determine which MeshFace is on the left side of the MeshEdge


I have similar question as I asked before but this time for Mesh.
I have ON_Mesh object and I need to determine which face is on left side and which face is on right side of each MeshEdge (except boundary edges) according to edge direction.


Hi Biljana,

Mesh faces are oriented counter-clockwise with respect to the face normal. Does this help?
