I understand the line vector, but can someone please explain what the surface and edge vector parameters are for? I would expect to see one or the other but not both. I don't know what each one is for...
Green fields are the vector of the surface. Imagine that you have a line on your roof, pointing straight north. If your roof has no pitch, the green fields would be 0,0,1. If your roof has a 1:1 pitch the green fields might be 0.7071,0,0.7071.
