Not sure. My goal here was to find the orientation of a Planar Quad Mesh.
Lorenz Lachauer gave me this link to the diploma thesis of Alexander Schiftner: http://www.dmg.tuwien.ac.at/geom/aschiftner/doc/diplomarbeit.pdf

Could this approach be used to deduce surface rulings, as I assume they would always be perpendicular to principle curvature?
