Hi all,

I frequently need to orient the vertices of triangles (ccw or cw). Is
there a simple way to do this? The reference point would be the inside
of a polyhedron but I can immediately think of a lot of exceptions (e.g.
concave polyhedra). Could I use an infinite point as a reference? Not
exactly sure how infinite points are defined...

Or does anybody know a good solution? Thanks for your help,

Jens
