It's an ordering thing with polygon nodes, Greg:-
For each face
For each node in face
If ( vertex pointed to by node hasn't been visited )
Strand index ++
If that makes sense.
I'm at the airport right now (groan) but I've some code that I can dig out
when I'm back in the UK. Sometime over the weekend.
